Lifespan Changes, Sex Differences, and Hormone Effects in the Primary Visual Cortex of the Rat and the Associated Area of the Corpus Callosum, the Splenium

Effects of aging were also investigated in Oc1 and the splenium. Examination of neuron number in aged animals (19-22 months) found that Oc1 was significantly impacted during aging, with both males and females losing neurons (18-20%) between day 90 and old age, maintaining the sex differences in neuron number. However, examination of the splenium in adult (day 120), middle age (12-13 months) and aged (18-26 months) animals showed no age-related deterioration. Instead, the splenium increased in size between adulthood and old age, demonstrating the regionally-specific effects of age in the rat.
