Fig. 5.

An interdigitating pattern of convergent, patchy corticostriatal terminals. Dual anterograde tracers were placed in anterior temporal cortex (blue) and prefrontal-cingulate cortex (red). The predominant uptake zone for the ‘red’ tracer was located in posterior orbitofrontal and anterior cingulate cortex; importantly, both regions were later shown to be a source of afferents to the striosome compartment of striatum (Eblen and Graybiel 1995). The ‘blue’ afferents may be inferred to have invaded the matrix compartment, potentially explaining the predominant interdigitating pattern.
