title: Effects of change of maternal environment during early postnatal development on behaviour in cataleptic rats.
abstract: Pinch-induced catalepsy was compared at an age of 2 weeks and at weaning in cataleptic GC and control Wistar rats reared by their biological mothers or subjected to reciprocal in-or cross-fostering. Besides, some open-field parameters were studied in the same groups of rats at an age of 2 months. Significant interstrain differences in all the behavioural parameters studied were found. Reciprocal cross-fostering tended to diminish interstrain differences in most parameters. It brought about a decrease of duration of pinch-induced catalepsy at 2 weeks and at weaning in GC rats, and an increase of duration of catalepsy at weaning in Wistar females. Besides, cross-fostering decreased the duration of freezing in the open-field test in GC rats at 2 months.
