Patch matrix compartments cortical inputs

Fig. 26. The relationship between the laminar organization of the cortex and the striatal patch-matrix compartments is diagrammed showing inputs from the prelimbic (A) and cingulate (D) cortices to the striatum. Corticostriatal neurons located in the deeper part of layer 5 (black cells in A and B) in each cortical area provide inputs directed to the patch compartment (black stippling in B,C, E and F), whereas corticostriatal neurons located in the superficial part of layer 5 (white cells in A and D) provide inputs directed to the matrix compartment (white stippling in B,C, E and F). Inputs from these cortical areas are somewhat greater to the patch compartment as compared to their inputs to the matrix compartment. The prelimbic and cingulate cortical areas provide inputs to a topographically related region in the striatum which overlaps to some extent for these two corticostriatal projections.
