title: Prenatal morphine exposure alters susceptibility to bicuculline seizures in a sex- and age-specific manner.
abstract: Bicuculline was used to investigate seizure susceptibility in pre- and peripubertal male and female rats exposed prenatally to morphine. Morphine-exposed males showed increased seizure susceptibility at prepubertal and decreased susceptibility at peripubertal ages. There was no difference in seizure susceptibility in morphine-exposed females at either age. Therefore, the present data suggest that males are more vulnerable than females to morphine-induced insults during prenatal brain development.
