Pregnant Long-Evans rats were injected daily with 40, 60, 80 or 100 mg/kg cocaine HCl (SC, 2% solution) from gestational days 7-20 (sperm positive = day 0). Daily doses were split with half given between 9:00-10:00 a.m. and half between 3:00-4:00 p.m. An ad lib-fed group as well as nutritional control groups that were pair-fed to the 80 and 100 mg/kg cocaine dams were also evaluated (N = 11-18 litters/group). The negative geotactic reaction of the offspring, evaluated from day 2-14 (birth = day 0), showed no group differences. Spontaneous alternation behavior in a T-maze showed no evidence of perseveration in any group on either day 21 or day 80. Most cocaine-treated offspring showed an altered preference in turning right versus left on day 21. Activity monitor behavior showed that the cocaine-treated and pair-fed offspring were hypoactive on day 20. Some degree of hypoactivity was still evident on day 49, but absent on day 80. The passive avoidance behavior of day 19 offspring showed no group differences in acquisition of task learning. The 100 mg/kg cocaine offspring did show significantly poorer retention of task learning 48 hr later. On day 80, no group differences were seen in passive avoidance behavior. Acquisition of an active avoidance behavior on day 80 was significantly poorer in the 100 mg/kg cocaine group.
