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 کاملEffects of morphine, buprenorphine, pentazocine and nalorphine on acquisition and extinction of active avoidance responses in rats.
The effects of subcutaneous administration of morphine, buprenorphine, pentazocine and nalorphine were studied at two dose levels in rats (low dose x 10 and high dose x 20 of equivalent human dose) on the performance of active avoidance responses using a shuttle box. Pretraining injections of both doses of pentazocine and low dose nalorphine impaired acquisition on day 1 and day 2. Morphine and...

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...

متن کاملDoes supplementary reinforcement of stereotypy facilitate extinction?
Results of several studies suggest that delivery of supplemental (social) reinforcement for stereotypy might facilitate its subsequent extinction. We examined this possibility with 9 subjects who engaged in stereotypy by including methodological refinements to ensure that (a) subjects' stereotypy was maintained in the absence of social consequences, (b) supplementary reinforcers were highly pre...
