Canalization of arousal in the preweanling rat: effects of amphetamine on aggregation with surrogate stimuli.

abstract：:In humans, maternal cues guide newborns to the maternal breast, and transitional cues may be present in maternal-fetal fluids. The aim of the present study was to determine the consistent presence of sensorial cues in three maternal-fetal fluids--amniotic fluid, colostrum, and milk--and test the ability of these cues ...
