Three experiments were conducted in rats to study the effects of acute and chronic LSD and 3,4-dimethoxyphenylethylamine (DMPEA) on acquisition of shuttlebox escape/avoidance and of acute DMPEA on performance in the shuttlebox of pretrained poor performers. In Experiments 1 and 2, separate groups of

β¦ Synopsis
Rats trained to avoid electrical shock in a shuttle box were given phencyclidine (0.0, 1.0, 5.0, or 10.0 mg/kg) prior to testing for 5 consecutive days. There was a dose-dependent increase in both avoidance and escape failures although animals continued to cross the barrier during intertrial intervals, indicating that they were capable of making the appropriate response. Little evidence of tolerance was found during the 5-day testing period.

Phencyclidine (PCP), haloperidol, and naloxone were administered alone and in combination to rats responding under a fixed-interval schedule for water presentation. Lower doses of PCP (0.25-2.0 mg/kg) and naloxone (0.001-0.1 mg/kg) produced increases while higher doses produced dose-dependent decrea
The effect of chlordiazepoxide on the retention of a passive avoidance response was determined in rats. Chlordiazepoxide or saline was given before testing in a two compartment passive avoidance response (PAR) apparatus or in an open field, and again after 48 and 72 h. The PAR was usually depressed
