Abstract

Ovariectomized female hamsters were selected for agrressiveness of non-aggressiveness toward a drug-treated target hamster. Animals in the aggressive group were found to have significantly higher levels of GABA binding in their brain 'midregions' (including limbic, striatal and diencephalic structures). There were no between-group GABA binding differences in cortex or pons/medulla and no differences in dihydroalprenolol (DHA) binding in any of these three regions. The groups did not differ on a variety of other behavioral tests including measures of activity, emotionality, feeding, and hormonally primed sexual behavior. The differences in 'midregion' GABA binding therefore may relate to levels of aggressiveness specifically.
