Abstract
Lesion of the midbrain ventral raphe nucleus greatly improves the avoidance learning efficiency of normal and isolated-aggressive albino Swiss mice. Since the lesion of this brain area selectively lowers the forebrain concentration of 5-hydroxytryptamine (5-HT), implications of the role of brain 5-HT in avoidance learning acquisition are discussed.
