Disruption of maternal behavior and appearance of cannibalism after ventral mesencephalic tegmentum lesions

Disruption of maternal behavior and appearance of cannibalism after ventral mesencephalic tegmentum lesions

Physiology & Behavior 23(2): 317-324

Maternal behavior in female multiparous rats was investigated after ventral mesencephalic tegmentum (VMT) radiofrequency lesions. Lesioned rats did not build nests before and after parturition, cannibalized pups (100%) during or shortly after parturition, and did not nurse their pups (0%). Fecundation and gestation were normal. The VMT region, limited dorsally by the nucleus ruber, ventrally by the interpeduncular nucleus and laterally by the substantia nigra, is an essential part of the Limbic Midbrain Area (LMA). A behavioral disorganization can be explained in terms of LMA-limbic forebrain relationships. The possible role of aminergic systems, as the dopaminergic A10 group, is discussed.
