title: A mosaic-like distribution of dopamine receptors in rat neostriatum and its relationship to striosomes.
abstract: The distribution of dopamine receptors in rat neostriatum was determined by means of light microscopic autoradiography of in vivo labeled binding sites for [3H]N-n-propylnorapomorphine and compared with the distribution of acetylcholinesterase histochemical staining. The distribution of dopamine receptors was non-homogeneous and patches of low receptor density were in register with acetylcholinesterase-poor striosomes. This suggests that the distribution pattern of dopamine receptors is specifically related to various input systems.
