Abstract
Maternal cocaine abuse during pregnancy is associated to neglect, abuse, and mother-child bond disruption, which directly affects infant development; therefore, various neurobehavioral problems of children of drug-dependent parents could be attributed to inadequate maternal behavior or prenatal exposure to drugs. Thus, the aim of this research was to analyze the effects of chronic cocaine administration during pregnancy on postpartum maternal behavior. To do this, 21 CD1 pregnant female mice were randomly assigned for administration of saline solution and cocaine (25 mg/kg/day and 50 mg/kg/day), from day 8 to 21 of gestation. After delivery, for 15 minutes a day, during 20 days, the frequency of occurrence of 16 behavioral patterns of maternal behavior was individually recorded, using an ethogram. Cocaine slightly affected maternal behavior frequency, although it may have affected other parameters, such as latency, duration, and sequence of this behavior.
