Inhibitory Avoidance with a Two-way Shuttle-box
so called passive avoidance), the animal precludes the aversive stimulus by not showing a behavior regularly shown in a particular environment. Inhibitory avoidance is acquired in only one trial, where the subject is punished for doing something such as entering a new compartment (test). Then, in a second session (retest), behavioral inhibition, for example not entering the compartment, is meas...
متن کاملElectrical stimulation of the hippocampus and acquisition of the conditioned avoidance response in shuttle-box in cats.
The effects of electrical stimulation and electrolytic lesions of the posterior part of the hippocampus on acquisition of the active avoidance response (AAR) in shuttle-box were studied in 35 cats. Both weak or strong hippocampal stimulation applied simultaneously with conditioned stimulus (CS) facilitated the acquisition of AAR. After discontinuation of stimulation the level of AAR performance...
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 کاملImprovement of shuttle avoidance by handling during the intertrial interval.
Rats handled between trials during shuttle avoidance training were superior to those not handled on several measures of avoidance learning; handled rats were nonetheless inferior to those receiving one-way training. A second experiment clearly demonstrated that differences between shuttle and one-way avoidance could not be attributed to differences in handling. Furthermore, hypotheses which exp...
متن کاملeffects of intermittent aerobic training on passive avoidance test (shuttle box) and stress markers in the dorsal hippocampus of wistar rats exposed to administration of homocysteine
objective: elevated amino acid homocysteine (hcy) levels and insufficient physical activity are the risk factors in alzheimer disease (ad) development. the effect of intermittent aerobic training on memory retention test and thiobarbituric acid reactive substances (tbars) and superoxide dismutase (sod) levels in the dorsal hippocampus of rats which were stimulated with hcy is investigated. meth...
