Abstract:
Recent neurochemical and anatomical findings delineating two compartments, the patches and the matrix, in the mammalian striatum, are described. Anatomical and neurochemical aspects of manipulations affecting behaviors related to S-R memory and reward correspond in certain respects to the features of these striatal compartments. These coincidences lead to an hypothesis concerning the function of the striatal compartments and their participation in neural systems controlling both immediate and learned behaviors.
