A correlated light- and electron microscopic double-immunolabeling study combining choline acetyltransferase immunocytochemistry with anterograde tracing of Phaseolus vulgaris leucoagglutinin (PHA-L) revealed that axons of the nucleus accumbens terminate on cholinergic neurons of the ventral pallidum. These findings are discussed with respect to the possibility that these cholinergic neurons may be part of parallel circuits, providing feedback to the same cortical and amygdaloid areas which innervate the nucleus accumbens.
