Environmental enrichment in BALB/c mice: effects in classical tests of anxiety and exposure to a predatory odor (2001)

Abstract

Our results show that EC mice were more active than SC mice in the elevated plus maze and the open field. Thus, possibly as a direct consequence of frequent changes in their breeding conditions, reactivity to a novel environment was reduced in EC mice. However, the cat odor test revealed no intergroup differences for behavior, although corticosterone levels were reduced in EC mice.
