Na, K- and Mg-ATPase activity of the cerebral cortex microsomal fraction has been studied and compared in adult and old rats. The activity of Na, K-ATPase decreases while that of Mg-ATPase increases with age. The total ATPase activity remains unchanged. The effect of acetylcholine on ATPase activity has been found to be age-dependent.
