title: The ventral striatopallidothalamic projection. III. Striatal cells of the olfactory tubercle establish direct synaptic contact with ventral pallidal cells projecting to mediodorsal thalamus.
abstract: After injection of HRP in the thalamic mediodorsal nucleus (MD) of the rat on one side followed by a superficial laminar heat lesion of the olfactory tubercle (Tu) on the same side, electron microscopic examination of DAB-reacted sections through the Tu revealed degenerating terminals contacting HRP-labeled neurons, confirming that a monosynaptic, two-neuron link extends, via a relay in ventral pallidum, between the superficial dense cell layer of the Tu and the MD.
