The White Chapter

The White Chapter

Water in sight
Robbed of life
Sealed with unrelenting grip
Incapacitated by apathy
Unable to do anything
Unable to be

The color of dry
In stark sarcasm to its nature
Smirking at our hope for the future
Hope for a better world
How do we know?
For all that is seen
Is the wind
Blowing away the white powder
That was unable
Unable to cling to family

Extreme Winter Sports Action Footage (EWSAF)

It snowed yesterday, somewhere between 4 - 8 inches. Which, to the well-informed, means one thing and one thing only...SLEDDING!! So after lunch, while we decided to take a look at what winter wonders there were in the Japan House and Arboriteum area, we see Nina and Michael, with Nina's childhood sled, just itching to slide down the hill on Orchard Downs. The hill was crowded. Families with children hitting the slopes. The cold winter wind did not prevent them all from having fun in the white powder. And it shouldn't have, because for all the blistering frost, it is honest-to-gosh fun in the purest. Letting yourself go with the snow.

But of course, you have to have the right equipment. Michael decided to do an experiment. Using our extraordinary knowledge in physics, we know that objects at rest, tend to stay at rest, unless acted upon by another force. Michael decided to test this using his car windshield sunshade as a sled. Now, theoretically, this should work. The snow should provide enough lubrication to offset the friction. And Michael's weight should be enough for gravity to pull him down...theoretically. The movie clip below shows the outcome of this experiment. Empirical trial number one.

Go Michael Go!!

Undaunted by human limitations, we next decide to perform a stunt which has never before been attempted in human history. We decided to record sports action footage of extreme sledding. What you are about to see is the shot as seen from the video camera mounted in front of a model 3000 sledding machine, with all the latest upgrades and safety features. Hold your breath, because your eyes will now be witness to one of the most amazing sports action perspectives ever.

Extreme Sledding!!

This concludes our winter episode of sports olympics. Tune in next time when we go to Extreme Summer Sports Action Footage or ESSAF!

Crepes at Carmon's

Carmon's is a French Creperie located in downtown Champaign. This would be my fourth time there. The decor is homely, bright with a tint of sophistication, yet not too modern, nor is too old fashioned. In other words, it is just nice. Which, to the senses, can sometimes be more delightful than either extremes. For one wishes to be at the crossroads between the past and the future, totally dwelling in the present. I've tried the beef stroganoff (good with reds), pork chutney, onion soup, curry chicken chutney, ratatouille, banana foster, peach streusel, and the suzette (which the movie clip below shows part of the making process involving flaming the grand marnier, and the photo top left is the finish product). All I can say is, this is one place, which every dish on the menu is worth trying once. And it is fortunate that the menu is short enough for that to be a realistic endeavor. Every dime is well spent to fill your senses with delectables.

Flaming the Suzette

Waffles and Bacon

This is a fantastic western style breakfast. Charlene made this. Good blend of sweet and salty. Crispy and juicy. Great to wake up to.

Ingredients
Ready waffles (either pre-made, or you can make from your own mix, if available)
Sweet potatoes (cut for fries)
Bacon
Pears
Maple syrup
Salt
Pepper

Method
Prepare the waffles using a toaster and set aside.

Fry the bacon strips in a pan till crispy. Once done, remove the bacon and place between napkins to soak excess oil, but save the oil in the pan.

Cut the sweet potatoes for fries, and fry them in a pan with bacon oil till crispy. This will take a few minutes.

Peel and cube pears. Place everything on dish. Add salt and pepper to fries, and syrup to waffles. Ready to serve.

Tilapia with Capers

This is a very unique filet dish. The fish is cooked so that the meat is flaky but moist. The capers add a sweet, sour and juicy flavor. The rice adds a plain contrast to the rich sauce.

Ingredients
A filet of white fish meat (Tilapia, Cod, Bass)
White rice
Capers
Vinegar
White wine
Butter
Spring onions
Salt
Pepper

Method
First, cook some white rice in a rice cooker, then go ahead and start preparing the fish.

Bring some water to boil in a pot. Once the water is boiling, place the fish filet in. This will cool the water for a while. Let the fish cook until the water is back to boiling again (this will take a few minutes). Once the water is boiling, take the filet out, and place on a dish. Now prepare the sauce.

Melt some butter in a pan. Cook the melted butter until it changes color. Then pour the hot butter onto the filet. Next, heat some vinegar and wine in the pan, reducing it. Once the mixture is boiling, pour it also onto the filet. Sprinkle salt and pepper. Add the capers and some slivers of spring onions. Place some white rice on the side, sprinkle some dried seaweed if desired.

Ready to serve.

Thanksgiving 2007: E-Poem

It was time.

Time to do anything
Anything but work.
This Thanksgiving break
We headed to Starved Rock.

We forded the streams
We conquered our fear
We reach to the top.

We even ourselves "caught" a deer.

A few days later,
we were out again,
this time it was noisy
But all the same
We were happy


We were out late
Late into the night,
And that's when it all started
We began to see some lights.


After which, we went in
for turkey and a din.
Prepared by Nina
Nina and Mr Lin.

The feast was a great
It was a fantastic
It filled our stomachs
We were almost ballistic

After all is eaten and said
All is said and done
We each one of us
Noticed it was fun

So for each and every year
Once a time
Time and again
We remember to be thankful
To be sober
and sane.

St Louis

St Louis is a pleasant 2 1/2 hr drive south-west of Champaign. We met Sam there as he was on his way up from Nashville after a friend's weekend wedding. We arrived at the St Louis Botanical Garden in time for lunch, and sat at the nice outdoor cafe area for a simple, but delightful meal amidst the beautiful plant life. The weather was awesome, and walking in the Gardens was definitely a much wanted breather. Click here for the [photos].

We also visited the famous arch of course. There is a museum at the base of it. And you can actually go up in it, but we missed the closing time at 5pm.

Downtown St Louis itself was a little quiet. For city like St Louis, it was actually hard to find a place where we could sit down and have a satisfying meal. We walked around the riverside area, saw a few pubs, but nothing eye-catching. We decided to drive around a bit further away from downtown and ended up around Washington University area. But still nothing inviting. We ended up eating at the hotel restaurant, which was actually not bad.

So all in all, a nice day trip, but plan your restaurant locations ahead.

Chicken Rice

Once of the most standard dishes in Singapore, the famous Hainanese Chicken Rice. Easy to make, light to the taste, and adaptable for all situations.

Ingredients
Chicken
Cilantro
Cucumber
Sesame oil
Light soya sauce
Rice
Ginger
Salt

Method
Cook your rice as per normal in a rice cooker, but add your chicken meat whole as well. This saves on cooking time, but it will taste better if you cook the chicken separately, however, if you do this, you would have to use chicken stock to cook your rice. Following our original plan, add the chicken into the rice and cook it together, also add a few slices of ginger, some sesame oil, and salt. Cook the mixture. Slice the cucumbers and cilantro for garnish. Once the rice is done, take out the chicken, slice it up. Serve on plate with garnish, add some light soya sauce and chilli sauce if required.

Dobin Mushi

This is a classic Japanese soup dish that has one of the most unique tastes. There is a slight burnt flavor that comes from the dashi stock cooked in a clay pot, an earthy flavor from the mushrooms, and a sour tinge from the citrus lime that is added. Definitely worth the effort on a cold night. This soup is typically served in a small clay tea pot with a small drinking cup. The size of the pot seals the flavor in, but if you don't have a clay pot, you could use any other pot that can be used to boil soup on low heat for extended times. Also, the typical soup is cooked using Matsutake mushrooms, which are very very expensive. I've used Shiitake mushrooms as substitute here, for the the poor man's version, but of course, nothing beats the original ingredients. Try as best you can to secure the freshest matsutake.

Ingredients
1. Matsutake or shiitake mushrooms (fresh is best, but if dried, soak overnight first)
2. Fish dashi (best made using the fish flakes you see on tofu dishes, that curl and move when served)
3. Soya sauce
4. Sake or rice wine
5. Cilantro
6. Shrimp
7. Chicken
8. Lime

Method
Soak the dashi overnight. Cut the mushrooms, shrimp and chicken into small bite size pieces, you don't need too much of this, just a small portion. Bring the dashi stock to a boil for about 10-15 min. Once the dashi flavor is cooked into the stock, remove the dashi, leaving the stock. Add a spoon of soya sauce, and a spoon of sake. Add the mushrooms, shrimp and chicken into the boiling stock and cook for about 10-15 min. Add lime juice from half a small lime, garnish with cilantro, and serve.

Grilled Steak

Oo La La. Fresh off my $10 grill from Walmart. Steak seasoned in red wine and thyme, asparagus, green peas, potatoes, and oh-so-good dinner rolls from the beefhouse, all done on the grill. Nice cool weather outside 52F, and sitting beside the glowing embers.

How To Make Teh Tarik

Teh Tarik, literally, pulled tea, is actually an Indian method of making milk tea. The milk tea containing condensed milk is poured from one container to another, which cools the tea down, and at the same time, introduces air bubbles. This gives it a lighter texture, and, as with most interactions between liquid consumables (such as wine) and air, brings out more flavor. Although, the average tea drinker will probably never notice the difference, watching the process of making this tea is a treat in itself.

The name Teh Tarik, is in fact a Malaysian word. Tarik means pull in Malay. This meshing of words and cultures is a result of exchange happening in the South East Asian regions because of the multi-cultural backgrounds present.

Presenting, how to make teh tarik...

Park-O Tex-O

As part of the lab shift to Dallas, we went down to check it out in the Lone Star state. I shun bian say hello to Mei. There are several ways to get to Dallas from Champaign. Drive = 12 hrs, Direct 6am flight from CMI airport to DFW airport = 2 hrs, mid-day flights with transit from CMI-ORD-DFW = 4hrs, staying put = priceless. Anyway, we took option number 3 and, as you can see, we start out strong. The flight was pretty good, from ORD to DFW, we got personal TV units, slightly larger plane. But then at touchdown, we had to wait pretty long for luggage, because it was such a big flight. Then we wait for Mr Hebrank to come pick us up after his game of Ultimate.

The car rental place is a 7 min shuttle bus ride from the terminal itself. And once you arrive there, its a humungous air-conned art museum, with car rental outlets just lined up for you to choose. Our Ultimate man came by, we rented an SUV, and drove to our hotel, Embassy Suites at Lovefield, Dallas. We then quickly got ready for dinner with Mei and John. Which was at a nearby steakhouse.



It was nice to catch up again. And it was fun to have the lab people along too.

After which, we checked into our huge room in the Embassy Suites.

The next day, we went to the Brain Health Center, which is just a few minutes away. Very impressive building. Very artsy. Definitely a good place to work. Right now, the lab space is still under construction, but when its done, it will be awesome.










After that we went to where the scanner is at the hospital. Also another artsy building. We got some scans done, and then, for us, we had to head back to good ole Chambana.














So of course, what would flying be if there were no delays? So they introduced a little 1 1/2 hr delay for us at DFW. But otherwise, the flight was ok. Got back...showered. And bed = priceless.

Check out the rest of the pictures by clicking here.

Oh yeah...this has got to be the best introduction ever...

Models that Account for the Same Data: The God Account

In reference to my post about models that account for the same data, one possible explanation for why there are so many religions is because of the principal component function in our minds (refer to the post). Here, we have the same data. But we refer to different dimensions to explain the data. Sometimes even omitting certain dimensions. Such omissions would lead to certain biases in explaining the data. And to the extent that the bias is critical (that is, to the extent that these biases are necessary for accounting for the truth), our explanation of the data will be off from reality. To the extent that the biases are not critical, we will not be off from reality.

The most accurate model therefore, is the one that most closely matches reality. Yet how are we to know reality? This is the problem of knowledge. Can we truly ever know anything since we are limited to our senses, five in all, and perhaps a little more. We have 5 dimensional information, and perhaps a little more. What if the data were more multi-dimensioned than our senses can experience? Even if we had secondary ways of measuring data from dimensions beyond our perception, our experience is still bounded by our perceptions. Thus, it appears that to ascertain reality, we need to transcend our 5 senses. But even then, how many senses or dimensions should we transcend? In theory, infinite. Which is of course, flatly impossible.

Therefore, the question is not about empirical proof anymore. We realize empiricism, limited to 5 senses, cannot ascertain reality. Really, all empiricism does is to come up with models to account for data within the 5 senses. Which has no consequence on reality itself.

We are back to the question: How can we know what reality is?

Models that Account for the Same Data

Perhaps what our minds are doing is accounting for the data. The data is everything around us that we experience with our senses. This information is fed into our neurons, which, by virtue of their network organization, perform some sort of operation on this information. This operation can be likened to a form of model fitting (for those of you who are familiar with the modeling world). Our neurons constantly flux in an effort to represent the information we encounter in the most stable possible way, that allows us to incorporate new information as well as to maintain old information, and even to allow old information to modify new ones.

Consider the method called principal components analysis. This is nothing but redefining the data in terms of another set of dimensions. It thus appears that the same data can be understood in different ways, without changing the data one bit. Furthermore, using one set of dimensions over another set is simply dependent on one's goals or assumptions when trying to arrive at an explanation or investigation.

So then, the question is, which approach is scientific?

On The Way...

So you see ah...so busy until the blog fresquenscies is so slow lah. Anyway lah. Updache all a bits. First, Charlene birthday happened. We celebrated with homemade spaghetti: shrimp, mushrooms, marinara sauce, red wine, and these three cakes from Cake Artist Studios on Bloomington Rd, Champaign, IL. Very good! If I remember correctly, one is called black berry something, one is called cappuccino something, and the last one is called chocolate something...something.

Then I had to go to Ann Arbor, MI to give a talk. This was kind of a last minute thing. But then had to go lor. Drive for 5.5 hrs (acherly, Charlene drove lah, atta girl!). Then stayed over night there before giving the talk the next day to the bunch at UMich. Quite a good crowd acherly. Met Ah Yu there, he was giving a talk too. We ate at some Korean restaurant thingy. Then after the talk, we drove back (another 5.5 hrs) but via Indianapolis, to go to The Beefhouse. Note: Beefhouse is at exit 4 on I-74 heading west, just before crossing the Indiana/Illinois border. Very good meat! Mmmm...can go back again...so by now, you should be able to tell, that I am somewhat broke oredi. Donations are welcome [www.gimmemahni.com].

And finally, I got my Master's in Psycho. Now, I am a certified genius, I'm sure! Certified man. got paper leh. Hopefully this paper can hepped me earn more mahni. If not, then is din deh lah. So all in all, although got many thing going on...its moving lah. Slowly but surely. For more good years!

Why is existence better than non-existence?

This is a toughie.

Formosa Formosa!

Ok ok. It may seem like I very the free, traveling everywhere. But really, you have to see me in between. I is very the busy one. Only rare chance got time to go see see things, meet meet people. So must cherish the moment. Anyway, Taiwan. Shiokanadenmatology!

I got a free ticket because I claim mileage on Singapore Airlines. SQ hwaaa! Is good man. So much better than all the other airplanes. Acherly, I think any Asian airline is much better than any US airline. Ok back to the story...

Touchdown at Taipei airport and went to Bei Pu to have lei cha. This is where you use the stick and grind the tea leaves into powder. And eat muah chee. And grind and grind and grind until your chiu sng already. Then the tea become oily oily. Then ask the lady add water. Then and only then, can you drink your tea. Maybe is because you work so hard. The tea taste great. Then, after tea, we head to Changhua. Spend the night there, get pampered. Wake up to lots of fruits! Very healthy breakfast. And then, its off back to Taipei.


Went to eat xiao long bao at the original Ding Tai Feng with Zhimao. The bao is so juicy. I say, better than the Ding Tai Feng in Singapore. Very good. Can go again. There were a lot of people waiting in line. For some weird reason, they were mostly nihon-jin. Don't ask me why. So we eat eat eat. Then we walk walk around Taipei. Go to the 101 building. Their MRT exactly the same as Singapore one man! They also got the LOVE sign.

Then during dinner, we also meet Charlene's lab people to eat eat eat again at some Japanese teppanyaki style thing. Then we went to her small sister's place to spend the night. Next morning, we got up, went to get tau hway and Taiwan mian sian for breakfast and watched Transformers movie. Then its off to Hualien!

Hualien is beautiful. The place where mountains run into the ocean. The Pacific ocean to the east, the mountain ranges, Taroko Gorge to the west. Cliffs that hit the ground at ninety degrees. Water as blue as the sky. The sky as blue as the water. Rocks with lines and holes and rivers. All the color and texture coming together to make you feel that you are at home in the earth. We spent the night first at Bright Moon home stay in Hualien, which is a very cool and quaint place where you stay in a family like situation. We check out the ye shi there also. Eat and eat some more. The famous niu pai of course! And guan cai ban. And bbq sticks. I miss ye shis. And then we spent the next night at Taroko Gorge, Formosa Hotel.

Then we came back to Taipei and had dinner with the sisters at this cool yakiniku place. Very nice food and a fun time. Spent the night at Yuan Shan hotel (check out Ghost in the Shell, SAC 2nd Gig). Next day had niu rou main. Then fly fly away back to sg. Going back there again soon!

Nihon Nihon!

Some of you may or may not be aware (what kind of stupid statement is that anyway?), that I went to Japan for holiday. Shiokanaden! Subarashi! Hontoni hontoni! The food is good. The service is great. The people are gentle, and ...interesting. The sights and sounds are captivating. And did I mention the food is good? I never bluff.

The first day, we arrived at Narita. Took the Kensei line to Ueno, transferred to Ginza line to go to Asakusa. This took all about 2 hrs or so. But it was a pleasant ride. The most impressive thing about it was the train itself. Absolutely quiet! Acherly its going very fast lah. But then you don't feel it at all. How do they do it? Some weird nihon-o technology must be.

Then we arrived in Asakusa. This is where the Kamenarimon is. The Thunder Gate! Mon= men2 = door, by the way. We stayed at Ryokan Shigetsu. Very decent priced, very nice experience. Sleep on tatami floor and all that. There was also an onsen on the roof. I soaked in it. You are supposed to do it with other people naked. Separate for guys and gals lah, of course. Koki, a friend we met at a conference in New York, brought us around there with his girlfriend.

After Asakusa, we went to Hakone. Dai kirei da! This is near Fuji-san and lake Ashi. Take the romance car, the odakyu-sen, to Hakone-Yumoto. Then take a bus to Hakone-machi. We stayed at Ryokan Yugiriso. The whole package man! One night. Dinner and breakfast. Sushi lah, hot pot lah, pickled stuff lah, and a lot of other things dunno what it is. And of course, got onsen. Sleep on tatami. Can cry ah. Then after that, can see see the area. Very nice scenery in front of the lake. And also can go shopping at Hakone-Yumoto, very nice rustic charm.

Next is back to Tokyo, Shinjuku. We toured Akihabara where there weird people acting out anime and singing on the streets. We also met Niwako who brought us around the Meiji Shrine and also dinner at a sushi place in Shinjuku station. I tell you, so many cool things...can die already.

I took so long to put all these down because it seems that words cannot describe lor. Anyway, next time coming again. Check out the pictures [click here].

Reverse Engineering Brain Networks: Testing the Brain like One would Test a Neural Network

Typical steps in a neural network modeling study are the definition of a particular cognitive phenomenon, the creation and definition of the network model by specifying the neural architecture, activation functions and the learning rules. One then sets out to test
how well the network model matches up with the phenomenon, and to the extent that it does and is parsimonious, and has neural plausibility, it is a good model.

It is then not difficult to imagine how we can do the same thing with the brain by treating it as a neural model that's already built, and we're just trying to discover its architecture, its activation functions and its learning rules. Thus, we run the brain through simulations, observe the input and resulting output, and hypothesize the parameters that led to the observation.

We can then reverse engineer these parameters into the model (which is what we do anyway), and again, test how good the model is.

HBM Conference 2007 Chicago

Went to Human Brain Mapping Conference last week. Stayed at Sheraton Hotel. We ate at several places during that time, so hungry...because always using brain, so all the sugar used up. But it was fun. First night we arrived, there were fireworks and the Blues Fest was on in Grant Park. Anyway, no photos because too busy working. Check out what was cool at the conference [click here].

Here are the eatery reviews:
Happy Chef Chinatown
Always my standard place to eat...we had dim sum there, although usually for dinner, you can do a set meal for very cheap (works out usually to be ~$8), and it comes with free lobster or crab.

Oysy
Japanese sushi place. Not bad...but probably Sai Cafe is better but more expensive. Anyway, its one of those modern sushi places. There's two outlets, one on Grand, and one one Michigan. Average cost ~$20-$30, depending on what you order.

Dao Thai Restaurant
Good food and cheap prices (~$6). Has some pretty authentic Thai dishes, and the restaurant has nice Thai looking decor where you sit on floors with wells in them so that you are the same height as the table...get it?

Gino's East
Took a while to get our pizzas, but that's because they were making it fresh, as any good pizza should be. The pizza is pretty good. Nice and thick. We had a mix of supremo and vege. The sauce was not too sweet or rich, so its good. ~$15. Giordano's near the Water Tower still has my vote.

John Hancock, the Signature Room on 95th Floor
What would a trip to downtown Chicago be without a brunch at the Signature Room? $20. Best view with food combination. Menu changes. Brunch is from 11.30am to 2.30pm. This is the same view you get as when you go to the observatory, for which you must pay ~$15. So go do the math...

Andy's Jazz Pub
In my opinion, this is the heart of Chicago, and the most worthwhile place to hang out for good music. Don't come here to have deep conversation. Come here to listen to the depths of music. Cover $5-$20. Drinks are decent, not too wide ranged, but enough, serves dinner too. Historically, several notable musicians have jammed here. I like the way you can sit right in front of the band, and also the jam nights...informal, naughty, crazy, eclectic, and it all gets into your ears. Trumpets, guitars, drums, piano, bass, the whole shebang.

House of Blues
Significant venue where many musicians have performed including Louis Armstrong. Its a theatre set up inside. Cover is more expensive, concert based. You'll have to check online to get tickets in advance. Serves food. I think its worthwhile to visit once.

Red Fish
Cajun style. Food is pretty good. ~$20. They have a live band. Plays rock.

Some Tapas bar somewhere...

Cool Studies at HBM 2007 Chicago

Day 1
Cultural Neuroscience
Thinking of culture using a top-down versus bottom-up framework. Trey Hedden (MIT) and Angela Gutchess (Harvard University)...notable speaker presentations.

Visual Field Maps, Plasticity, Reading
Discovery of retinotopic visual representation in visual cortical areas other than V1. Apparently, V2, V3, even V4 and MT have some retinotopy. Speaker session by Brian Wandell (Stanford University).

Day 2
Brain Noise
Didn't attend this one, but it seems that people are looking into neural noise as a predictor of subsequent brain activity and behavior. McIntosh was one of the speakers.

Manipulative Neuroscience
Awesome talk by Mitsuo Kawato (ATR, Kyoto). He is the brainchild of DB, humanoid robot that is able to mimic human movements by visual observation, eg drumming, juggling, dancing. The talk covered latest research about controlling robot movements through brain-computer interface as well as visual and tactile feedback.

Perceptual Decision Making
Great talks relevant to the visual discrimination project. Generally, I got ideas about how to proceed with the project in terms of possible analyses, and also the fact that others have done this before. The main question is, how does the brain make perceptual discriminations of visual information? What are the mechanisms and neural correlates? Most notable speaker for me here was Paul Sajda.

Day 3
Dual Brain Systems
Control vs Representation systems in the brain. Typically showing that the control network resides in frontal, parietal regions, and representations in the primary and secondary unimodal areas. Check out www.walterschneider.net.

Repetition and the Brain
Another notable symposium of talks. Kalanit Grill-Spector hosted this one. The topic is self-explanatory, but there were some main novel directions. There is distinction between repetition suppression for immediately repeated stimuli vs stimuli repeated over interspersed trials (Grill-Spector). There is an interesting finding that for interspersed trial repetition of object naming tasks, pre-op patients for removal of lateral anterior temporal poles showed normal repetition suppression of repeated objects was observed in the ventral visual areas. But after operation with temporal poles removed, suppression disappeared even in lower perceptual areas suggesting that suppression has a top-down source in this case (Rik Henson). Another contention was Grill-Spector's testing of the fatigue vs facilitation models of adaptation effects. She found evidence for fatigue rather than facilitation, but note that her design involved immediate repetition.

Day 4
Representation and Processes
Didn't attend all, but most notable for me was John-Dylan Haynes' talk on reading hidden intentions in the human brain. They used classifier algorithms on clusters of voxels in the whole brain to identify brain areas that would reliably discriminate between stimuli. This could be applied to the visual discrimination project.

HBM: Ideas: Visual Discrimination Project: General Questions

1. Is there poorer behavioral perceptual discrimination with age?
2. If so, what are the neural correlates? Is it a perceptual representation problem (ventral visual dedifferentiation)? Or is it a selection/decision-making/control process problem (noise, non-selectivity in frontal cortex)?
3. Is this the same across all types of stimuli (eg faces, patterns, random shapes)?
4. Is there a constant in terms of brain activation pattern across all individuals which is necessary for discrimination?
5. Which parts of the brain are predictive of whether the individual is able to discriminate visual stimuli (classifier algorithms on whole brain)?
6. What leads to individual differences in performance? And if all individuals are equated at some level of performance, do the individual differences disappear?

John 3:22-26

"After these things..." refer to the Passover and Nicodemus's visit. It is important to note that Jesus was gathering quite a crowd here, and that there was quite a religious sentiment going on in the Judean region, especially in Jerusalem. Also note that Jesus' disciples were baptizing. Referring back to the section in the John posts on baptizing we see that it was quite a common practice, however, its origins are not clear, and what Jesus' disciples were baptizing the people for is also not mentioned. It might be that while they were baptizing, Jesus was also teaching, since it is mentioned that He Himself did not baptize. This also tells us that Jesus' disciples at this time might have some religious status and recognition, being associated with a popular teacher, Jesus.

In any case, there arose a debate. How often, when there is a large crowd of believers, even religious leaders, there will also be a debate. And note that it was a purification, a debate about rituals probably between John's disciples and the Jews (probably the Pharisees), a dispute about who is doing what and who is right about it. Perhaps we can get the sense here that while the Pharisees were in legal religious authority, there were bands of teachers who might have disagreed with them, and there was constant voicing of religious ideas. Can we map this on to the way churches and religious organizations behave now?

But note even more surprising is that while the dispute was about purification, what John's disciples asked John about was nothing about purification but they were concerned about Jesus having more followers than John! Perhaps they were not really concerned about purification after all, perhaps it was bothering them that this thing was happening, and the unrest made them choose a topic just to vent? Again, do we do that ourselves? This is a call to re-examine our motives, no matter how admirable, we may have the best of intentions to dispute about religious motives and practices, but is that really our concern, and even more important, is that really what matters? Did we miss the point about what Jesus is doing?

Examine John's response deeply, because it seems in contrast to his disciples' and perhaps may be what John the author is putting as an example for us to follow in response to the Christ.

"He must increase, but I must decrease".

We are but witnesses to a more glorious Light. Always remember that. Be humble. Especially in the presence of One who comes from above and testifies to that which He has seen and heard. This statement constitute another testimony from John the Baptist as quoted by John the author, another testimony about the Christ. And Christ's testimony, through His actions, about Himself.

CNS 2007: New York City

New York, New York. The greatest city on earth...lah. We walk here walk there, walk everywhere. This photo show the city from the New Jersey side. A dense fog is covering the midtown area. Very thick, very mystery one.

Anyway, someone may is being asking me, why you go there ah? So I have to tell you, is not for fun one ok! Is for work. We is actuallying doing work lah. Conference. CNS Conference. Stand for Cognitive Neuroscience Society lah. Is for people who do my kind of work one, neuroscience. About the brain lah. Anyway, as you can see, we are very busy. So cannot talk very long. We are constantly finding out new, and interesting and important things, so also have to keep ourselves fit in order to maximize productivity. This next photo is showing Wenjing eating the duck bones, then Blair is eating the fish bone. See we very poor, eat only bones.

So we think this one is asking us "Kua Si Mi?" That's means is got very stylo right? Because got attitude. Then you know this one is for when you dunno what jiu this is, you ask the store owner, he will recommend and say "Simi jiu you want?" Then of course you say "yes!"

Then not say I say what lah, but there is a very good sushi place called Yuka in the Upper East Side, this is in the upper side, in the east. That side. Is eat all you can one, anytime. Most New York eat all you can is only on certain days only and at some times only. This one is everyday, anytime also can. Only about $20. Is cheap already lah for New York. Only thing is you must not over order. So if you order, then never eat, then must pay the full price for ala carte. Remember ah, don't order too much, then no more siao mei mei price.

Why did Jesus Christ have to die?

There are many aspects to this question, but I would first deal with the most direct one and leave the rest for later comments and feedback.

Christ died because of our sin. Therefore, first we have to know what sin is. Sin is not just doing "bad" things like stealing, lying, or even killing. The core of sin is not knowing God as God. We all have sinned in that we all are born into this world not immediately knowing who God is, and not immediately acknowledging Him. All of us, at one point in our lives, were separate from God. This is a result of the original sin from Adam. But the sin also lies on us as well.

The result of our sin, is our death. Not just physical death, but death as separation. That is, once we are separated from God, we remain always separated. The problem is that God does not have sin, and therefore there is separation. On the other hand, God does not think that this separation is totally good. It is better for us to be with Him. So He worked out a way for us to be with Him again, even though we have sinned. The answer is Jesus.

Jesus Christ is God. Although He is God, He took on our sin, and died. This at once forms a bridge. It is both shocking as well as beautiful all at once, because God who cannot even have a hint of sin, took on our sin. And God, in whom is life itself, died. This might sound impossible, or ridiculous, or contradictory at first. But consider that there is a lot about God we don't fully understand. Furthermore, what is impossible to man, is possible to God. To live and die at the same time, to be pure but tainted at the same time. This is a radical concept, that perhaps we can slightly identify with in the form of our own emotions. How we can feel so completely elated but hollow, sad and happy, worried but at peace, angry yet in love, hate but respectful. How we can be many persons yet the same person at one time. Is it any more impossible for God to have this characteristic too but in infinite terms?

In any case, once Christ died, we see that the separation is made null, because God crossed over to our side, and in doing so, brought us back to Him. There is identification and acknowledgment. There is also a form of payment, as it were. A ransom for the price of sin. Sin meant death for us, but in our stead, Christ died. Ironically, it is Christ/God that defined that sin means death. So in essence, He was both fulfilling His own law as well as abolishing Himself and His law.

The story doesn't end there of course, because Christ also rose again from the dead.

Parko Cho-O

No, this isn't a tribal dance. No, this isn't us burning the house. It is us saying goodbye to a dear friend. Parting is never easy. Which is why we do it with some partying. Parko Cho-O was held at Hessel Park, 6pm. BBQ, good food, good company. At first, the weather forecast threatened to thunderstorm, but, I quote someone, "60% chance for thunderstorm means, 40% chance". It all turned out well. People gathering wood, people burning marshmellows. Everyone just being plain crazy. We wish you all safe journey, and a better road ahead.

Check out the awesome pyro fest [movie].
