Developmental exposure to methylmercury alters behavioral sensitivity to D-amphetamine and pentobarbital in adult rats.
Female rats were exposed to 0, 0.5, or 6.4 ppm methylmercury in their drinking water before mating, and throughout gestation and lactation. When the female offspring were 4-6 months old, they were trained to respond under a multiple differential reinforcement of high rate (DRH) 9:4-- Extinction schedule of reinforcement. No differences among exposure groups were apparent in steady-state behavio...
متن کاملInteracting effects of handling and d-amphetamine on avoidance learning.
Rats were injected with either saline or 2 mg/kg of d-amphetamine 10 min prior to 50 trials of training with either the one-way, shuttle or shuttle-with-handling procedure. One-way training yielded more avoidances and shorter avoidance latencies than did either variant of shuttle training; it was not affected by the drug. The frequency of avoidances under shuttle training, on the other hand, wa...
