Table 3.

Effects of ACPC and MK-801 on omissions (total number of trials omitted during a 100-trial session), correct response latency (time from the stimulus onset to a correct response), reward latency (time from a correct response to the retrieval of food from the magazine), and perseverant responses (total number of responses emitted after a correct response has been made) in the five-choice serial reaction time task. Values represent the mean (±SEM). N = 9–12 rats per dose (ACPC study) and 7–8 rats per dose (MK-801 study)
