Serotonin-mimetic and antidepressant drugs on passive avoidance learning by olfactory bulbectomised rats.


Olfactory bulbectomised rats were treated with drugs and their rate of acquisition of a passive avoidance task was measured. The acquisition-rate, which is disturbed by the bilateral ablations, was completely restored by acute administration of fenfluramine or fluoxetine. Partial restoration was found with quipazine. Clonidine was without effect. Repeated treatments with imipramine and mianserine improved passive avoidance of bulbectomised rats. Metergoline blocked these effects of imipramine and mianserin. These results indicate a serotonergic mechanism in the effect of antidepressants on olfactory bulbectomised rats.
