Effect of differential rearing on brain, liver and adrenal tissues.
Brain, liver, and adrenal weights were measured in rats differentially reared from 28-60 days of age. Relative to the standard colony rats, enriched rats had heavier brains but lighter livers. Relative to the standard animals, impoverished rats had heavier adrenals. These results confirm differential rearing influences on organs other than the brain.
