To ascertain whether behavioral effects of benzodiazepines are altered by exposure to microwave radiation, we compared the performance of male, Swiss CD1 mice in the staircase test 30 min after pretreatment with chlordiazepoxide (8, 16, and 32 mg/kg, IP) and immediately following a 5-min exposure to microwave radiation (4, 12, and 36 W/kg, continuous wave,(More)
We previously demonstrated that behaviorally equivalent heat and cold stressors interacted with d-amphetamine (AMPH) treatment to produce different effects in rats responding for food on a fixed ratio 15 (FR15) schedule of reinforcement [25]. The present study was carried out to determine if these stressors differentially affect the disposition of AMPH to(More)
The interaction of two qualitatively different but behaviorally equivalent stressors with the behavioral toxicity induced by d-amphetamine (AMPH) was examined in rats. Stress, administered by immersing the rats in either hot or cold water, suppressed fixed ratio 15 (FR15) operant responding 50% and disrupted thermoregulation. AMPH (1, 2 and 3 mg/kg)(More)
Rats were immersed in 20 cm of cold (15 or 20 degrees C) water for 1, 2.5 or 5 min and were tested 15 min later on fixed ratio 15 (FR15) operant behavior for 30 min. Linear regression analyses predicted that 4 min exposure to 20 degrees C would suppress FR15 behavior 50%. Subsequent exposure to 20 degrees C water for this time period resulted in 53%(More)
An experiment was undertaken to determine the effects of pentobarbital sodium on intraspecific attack behavior in male Siamese fighting fish in an attempt to extend earlier findings with chlordiazepoxide and secobarbital sodium. Pairs of fish fought while immersed in 20 microgram/ml or 40 microgram/ml pentobarbital sodium or plain water. The 40 microgram/ml(More)
Pigeons were injected intracerebrally with either puromycin (PM) or control saline solution following training for one 12-min session on a visual discrimination. Injections were made either immediately following training, 1 hr later or 24 hr later. Retention testing 3 days after training showed that PM produced marked amnesia in the first two groups, but(More)
