Subdivisions of the primate substantia nigra pars compacta detected by acetylcholinesterase histochemisty.
Acetylcholinesterase-poor and acetylcholinesterase-rich compartments have been identified histochemically in the substantia nigra pars compacta of the squirrel monkey. Some of these compartments have clear correspondents in sections immunostained for tyrosine hydroxylase and in sections stained for Nissl substance. Clustering patterns of neurons retrogradely labeled after tracer injections either in the caudate nucleus or in the putamen were found to be related to these histochemical and cytoarchitectonic specializations of the substantia nigra pars compacta.
