Behavioral changes in 2-month-old rats following prenatal exposure to antibodies against synaptic membranes.
Two-month-old male offspring of rats injected intravenously on day 19 of gestation with antiserum to synaptic membrane fraction showed marked behavioral deficits on a DRL (differential reinforcement at low rates) training paradigm. These behavioral deficits included perseveration, slow acquisition rates, and poor retention. Offspring of pregnant rats injected with antiserum to galactocerebroside or isotonic saline did not show these behavioral effects.
