prompted by recent findings suggesting that the basal ganglia and possibly the limbic midbrain area and brainstem reticular formation may be represented within the general learning system of the rat brain , the current study was undertaken to assess the learning ability of different groups of young rats prepared with bilateral lesions to either the caudatoputamen , nucleus accumbens , ventral pallidum , ventromedial thalamus , habenula , subthalamic nucleus , pedunculopontine tegmental nucleus , dorsal raphe , ventral tegmental area , anterior pretectal nucleus , superior colliculus , inferior colliculus , or red nucleus .
