"Isotretinoin does not reduce learning and memory and our study suggests that it may instead lead to a dose-related improvement in specific aspects of hippocampal learning and memory. Retinoic acid functions in the hippocampus as the active metabolite of vitamin A, suggesting that this may be a limiting factor in the human hippocampus and addition of exogenous retinoic acid brings levels closer to an optimal state."
