Puberal status and sex differences: Activity and maze behavior in rats

This study assessed sex differences in spontaneous wheel running and maze performance in relation to puberal status in rats. No sex differences were found prepuberally in either task whereas, postpuberally, females exceeded males in wheel running and males made fewer maze errors than females. Postpuberal males and females were less active than independent groups of prepuberal males and females, respectively. Although mature females made more errors than prepuberal females, no differences were found between independent groups of pre- and postpuberal males.
