Abstract

Radioactive proteins seen in autoradiographs of the rat striatum after injection of radioactive leucine into the substantia nigra are not evenly distributed. Areas of more intense labelling are regularly spaced in the nucleus in rows parallel to the edge of the striatum.

The pattern is reminiscent of the innervation in young animals where ‘intensely fluorescent islands’ are seen. It is suggested that the areas of higher activity may correspond to the areas of dense labelling reported by others in sections of the striatum stained for acetylcholinesterase.

    The patch/striosome and matrix also differ in their cortical innervation. The prelimbic cortex preferentially innervates striosomes [13], whereas other prefrontal, motor, and sensory cortical areas provide inputs to the striatal matrix [25,26]. The orbitofrontal cortex has been shown to project to both striosomes and matrix [27,28].
