Mean distance traveled (±SEM) per 5-min time block during the behavioral testing session on PD 18 (these are a subset of the rats shown in Fig. 5). The male and female rats (n = 4 per group) included on this figure were injected with 0 μg NPA on the test day. On PD 17, rats were given IP injections of SCH23390/sulpiride (D1/D2 protected) or saline/saline (nonprotected) prior to EEDQ or DMSO infusions.
