Stimulus control was established in a group of nine rats using a dose of EGb 761 of 10 mg/kg, administered i.p., 15 min before training. A two-lever operant task using a fixed-ratio 10 schedule of sweetened milk reinforcement was used.

The results of studies on mice indicate that the antinociceptive effects of kappa-opioid agonists are due, in part, to activation of the 5-HT2 type of serotonin receptor. One objective of this study was to determine if the discriminative effects of
Experiments were designed to distinguish between central and peripheral effects on temperature preference and body temperature of drugs injected intraperitoneally (IP) in infant mice ranging in age from 3 to 10 days postpartum. These compared a drug restricted to the
Several studies have demonstrated a paradoxical form of antinociception induced by the repeated administration of opioid antagonists accompanied by exposure to a painful stimulus. The underlying mechanism of this naloxone-induced antinociception (NIA) is still unknown, but the results of several
The kappa opioid, U50,488, was examined alone and in combination with the 5HT2 antagonists, ketanserin, pirenperone and LY 53857. Squirrel monkeys responded under a shock titration procedure in which shock intensity increased every 15 s from 0.01 to 2.0 mA
