More hippocampal neurons in adult mice living in an enriched environment (1997)

Abstract

Mice reared in an environment enriched with running wheels, tunnels and toys possess more hippocampal neurons than litter mates reared in barren standard cages. It is likely that these extra neurons contribute to the enhanced performance in learning tasks showed by enriched versus non-enriched mice.
