Abstract
Examined the active- and passive-avoidance performance of male Long-Evans hooded rat controls and Ss with lesions in the interpeduncular nucleus, ventral tegmentum, combined interpeduncular nucleus and ventral tegmentum, and the stria medullaris-habenula (N = 65). Impaired passive-avoidance performance was noted in all groups with lesions, whereas only the groups with lesions in the interpeduncular nucleus and stria medullaris-habenular nucleus had facilitated active-avoidance performance. Results suggest that the stria medullaris tract, habenular nucleus, habenulopeduncular tract, and interpeduncular nucleus serve as significant anatomical pathways concerned with the acquisition of both active- and passive-avoidance performance, whereas pathways traveling in the ventral tegmental area dorsal to the interpeduncular nucleus are involved only in passive-avoidance responding.
