Effects of systemic NMDA antagonists on the number of correct responses and response latencies during a short stimulus challenge.

The effect of MK801 (0.03 mg/kg, i.p.), PCP (0.3 mg/kg, i.p.), and ketamine (1.0 mg/kg, i.p.) on correct responses and response latencies in a VITI version of the 5CSRTT under an acute attentional challenge. Results are for the total population, mean ± SEM, n = 12 animals per group, within-subject,*p**p5CSRTT 5-choice serial reaction time task, Csec centiseconds, VITI variable inter-trial interval.Effects of systemic NMDA antagonists on the number of correct responses and response latencies during a short stimulus challenge.
