Impairment of conditioned active avoidance in adult rats given corticosterone in infancy.

abstract：:The preweaning behavioral development was compared in 3 hamster species: the golden (Mesocricetus auratus), Chinese (Cricetulus griseus), and Djungarian (Phodopus sungorus). Differences in the age of appearance of action patterns could not be summarized by simply ranking species on either precocity or developmental sp...
