Department of Physiology-Anatomy*, Department of Psychology**, and Laboratory of ChemiealBiodynamies***, University of California, Berkeley, California 94720 Littermate, S1, male rats were exposed to enriched or impoverished environments for varying periods of time. From photomicrographs of the occipital cortex, neuronal parikarya and neuronal nuclear measurements were taken. In the 25- to 105-day age group, the neuronal nuclear area of the enriched animal was greater than that of the impoverished by 11.7% (P
