Active Avoidance Conditioning in Rats: Absence of Sex Difference and Estrous Effect
le rats in reproductive and non-reproductive behaviors have been reported in several studies. This behavioral dimorphism has been registered in running wheel activity, reactivity to footshock, intracranial self stimulation (Diaz-Veliz et al., 1989), spatial learning (Warren et al., 1990), lever-pressing (Van Haaren et al., 1990) and classical conditioning (Wood and Shors 1998). However, other w...
متن کاملEffects of acute intra-hippocompal injection of bupropion on active avoidance learning in rats
Introduction: Learning and memory deficits in some diseases are new subjects of research. Bupropion, as dopamine and noradrenaline reuptake inhibitor and an antidepressant agent, has been previously shown to affect learning and memory processes. This study was designed to test the effect of intra-hippocompal bupropion injection on active avoidance learning task in rats. Methods: Adult male ...
متن کاملThe role of nucleus accumbens and dorsolateral striatal D2 receptors in active avoidance conditioning
The role of dopamine (DA) in rewarding motivated actions is well established but its role in learning how to avoid aversive events is still controversial. Here we tested the role of D2-like DA receptors in the nucleus accumbens (NAc) and the dorsolateral striatum (DLS) of rats in the learning and performance of conditioned avoidance responses (CAR). Adult male Wistar rats received systemic, int...
متن کاملEffects of stress and of amphetamine on passive avoidance conditioning in rats.
This study examined the effects of immobilization stress combined with water immersion (ICS) and/or amphetamine (AM) on different memory phases in the passive avoidance task in rats. The performance of rats was evaluated in the retention tests 24 and 48 h after a single acquisition trial. ICS exposure lasting 1 h impaired retention of the learned avoidance response if applied 2 to 4 h before or...
متن کاملHippocampus and two-way active avoidance conditioning: Contrasting effects of cytotoxic lesion and temporary inactivation.
Hippocampal lesions tend to facilitate two-way active avoidance (2WAA) conditioning, where rats learn to cross to the opposite side of a conditioning chamber to avoid a tone-signaled footshock. This classical finding has been suggested to reflect that hippocampus-dependent place/context memory inhibits 2WAA (a crossing response to the opposite side is inhibited by the memory that this is the pl...
