Chronic treatment with clomipramine and desipramine induces deficit in long-term visuo-spatial memory of rats.

Although the effects of antidepressants in brain neurochemistry have been extensively studied, there are scarce and inconsistent data on the effect of these drugs in learning and memory. The authors studied the effect of daily administration of a single dose of either clomipramine or desipramine, two monoamine-reuptake-inhibitors with preferential serotonergic and noradrenergic profiles, respectively, during 15 days, on the visuo-spatial memory of adults rats measured through their performance in an eight-arm radial maze. Rats receiving 10 mg/kg i.
