Brain weight increases resulting from environmental enrichment: a directional dominance in mice

Science. 1970 Aug 21;169(3947):776-8. doi: 10.1126/science.169.3947.776.

Abstract

A genetic analysis of brain weights of 544 mice reared in either enriched or standard laboratory environments indicated significant directional dominance in the percentage of increase in brain weight as a result of enrichment.
