the present autoradiographic study has produced evidence that this dichotomy in the striatopallidal projection is to a large extent continued beyond the globus pallidus : whereas the efferents of dp were traced to the subthalamic nucleus and substantia nigra , those of vp were found to involve not only the subthalamic nucleus and substantia nigra but also the frontocingulate ( and adjoining medial sensorimotor ) cortex , the amygdala , lateral habenular and mediodorsal thalamic nucleus , hypothalamus , ventral tegmental area , and tegmental regions farther caudal and dorsal in the midbrain .
