摘要：
We investigated whether increased light input can counteract the age-related decrease in vasopressin-(AVP) and vasoactive intestinal polypeptide (VIP)-expressing neurons of the suprachiasmatic nucleus (SCN) by determining the numbers of these neurons in rats of different ages, housed under low or high intensities of light. The significant age-related decrease for AVP was prevented in old animals after high light housing. For VIP, no effects were found.
