Increasing neurogenesis might prevent drug addiction and relapse
"Researchers hope they have begun paving a new pathway in the fight against drug dependence."

This makes computational sense. Adding new neurons creates the possibility of forming new inhibitory connections, as well as de-potentiating the strength, or contribution, of existing ones. Such predifferentiated neurons serve as fresh unwritten computational space for which new behaviors and cognitions can be learned. In addition, old pathways which have been entrained and which are hard to change (because of prolonged experience or intensity) can have their effects counterbalanced.
