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

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 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

Action potential duration (APD) lengthening is believed to underlie the cardiac arrhythmogenicity of ketanserin, a serotonin (5-HT)2A/2C receptor antagonist. We wished to determine (a) whether this activity involves blockade of 5-HT2A/2C receptors and (b) the precise mechanism of ketanserin-induced APD

The mouse defense test battery (MDTB) has been designed to investigate defensive reactions in Swiss-Webster mice to situations associated with a natural predator, the rat, such as flight, avoidance, defensive threat, defensive attack, and risk assessment activities. The present study
