| Research Abstract |
Mammalian species living in temperate zones exhibit seasonal fluctuations in stress responses, affective status, and metabolism. This study clarified that photoperiod regulates hypothalamic-pituitary-adrenal axis via adrenal sensitivity in rats and mice. This study also clarified a potential animal model for seasonal affective disorder, a model that exhibits photoperiodic responses of mood-related behaviors. This study further clarified the interaction between photoperiod and nutrition in rats.
