Rats tested for 1 h in the Behavioral Pattern Monitor (BPM) after injection of the mixed serotonergic agonist d-lysergic acid diethylamide (LSD) exhibit a behavioral profile similar to that produced by various hallucinogenic 5HT-2 agonists. The characteristic effects of the hallucinogens include suppression of locomotor and exploratory behavior and a preferential decrease in entries into the...
Behavioral profiles composed of both locomotor activity and investigatory behavior were established for the 5HT-1A agonists 8OHDPAT, buspirone, gepirone, and ipsapirone using rats tested in a Behavioral Pattern Monitor. Typically these compounds dose-relatedly decreased horizontal locomotion and investigatory activity during the first half of the 1-h test session. Time-course studies revealed...
