The goal of the present study was to determine if the medial agranular cortex (AGm) that is thought to contain the supplementary motor area in the rat receives the pallidothalamocortical pathway. A double labeling paradigm was employed whereby injections of the anterograde tracer Phaseolus vulgaris-leucoagglutinin (PHA-L) into the entopeduncular nucleus (EN) were combined with injections of the retrograde tracer cholera toxin subunit B into either the rostral or caudal part AGm in the rat. We found that the pallidothalamic projections occupied a crescent shaped arc within the thalamic ventral anterior-ventral lateral nuclear complex (VAL) and ventral medial nucleus (VM). Additional efferents projected to LD/LP, MD, Pf and CL. Dense projections were also found to LHb. In addition, we found that a wide band of cells extending from rostral thalamus including VAL and VM through caudal thalamus including MD, Po, LD/LP, Pf and CL projected to either the rostral or caudal parts of the AGm. The greatest coincidence of the pallidothalamic efferents and AGm thalamocortical cells was found in VAL and VM where numerous PHA-L varicosities were found in close apposition to CTB labeled cells. Synaptic contacts between VAL thalamocortical neurons and pallidal terminals were verified in the electron microscope. These results demonstrate for the first time the pallidothalamocortical pathway by way of VAL to the AGm in the rat.
