Abstract: | We studied the effect of repeated intraperitoneal treatment with dehydroepiandrosterone in doses of 0.1 and 0.7 mg/kg on conditioned-response
activity and behavior of adult male rats. The effect of dehydroepiandrosterone on learning was estimated in conditioned active
and passive avoidance response paradigms. Chronic administration of dehydroepiandrosterone in low and high doses had no effect
on retention of conditioned passive avoidance response in adult male rats 24 h after learning. However, chronic administration
of dehydroepiandrosterone in low dose impaired acquisition of the conditioned active avoidance response. It should be emphasized
that chronic administration of dehydroepiandrosterone in high dose did not modulate acquisition and retention of this reaction.
