The Anatomical Substrate for Telencephalic Function. Questo articolo non è disponibile.The Anatomical Substrate for Telencephalic Function

This study is based on the thesis that the purpose of the telencephalon is to enable an animal to make decisions in new situations. The authors propose a model for the performance of this function based on the combination of a selection system with a sens
