A study was made of the effect of a two-week administration of chlorimipramine, zimelidine and a morpholine derivative on benzodiazepine receptors of the mouse brain. The animals which received antidepressants demonstrated a significant increase in the binding sites of 3H-flunitrazepam without any changes in the dissociation constant as compared to control. The data on the evoked aggressiveness and latency of tonic corasole convulsions in the antidepressant-treated animals support the functional importance of the discovered changes in benzodiazepine receptors.
