The research, published by Cell Press in the May 28 issue of the journal Neuron, provides intriguing insight into the mechanisms that help the human brain rise to the formidable challenge of adaptive decision making in the real world.img src=”http://feeds2.feedburner.com/~r/BrainMysteries/~4/JunXQZ3WTZM” height=”1″ width=”1″/

Mutations of genes that produce a critical cell-adhesion molecule involved in the work were previously linked to autism.img src=”http://feeds2.feedburner.com/~r/BrainMysteries/~4/vNTIO3hkUTs” height=”1″ width=”1″/
