Abstract
Rats with bilateral lesions in the septal and ventromedial hypothalamic nuclei were compared for emotionality rating under two conditions. In one condition rats were handled every day, while in the other condition, they were not handled until 3 weeks after surgery. In both handled and nonhandled situations, septal-lesioned rats show attenuation of hyperemotionality, while ventromedial-lesioned rats show no such attenuation. The lack of attenuation of hyperemotionality in ventromedial-lesioned rats probably reflects an important integrative role played by this area in emotional behavior.
