pineal

基本解释

However, as your query intimates, there is more to the “winter blues” than the seasonal variation of light to the pineal gland.
但，正如你的问题提到的那样，“冬季忧郁”不仅仅只来自于光照的季节性变化对松果腺的影响。
In normal circumstances, however, the SCN reacts to the lengthening nights by instructing the brain's pineal gland to secrete more of the hormone called melatonin.
然而，在正常情况下，SCN对夜晚延长的反应是，它会指示大脑的松果腺增加褪黑激素的分泌。
The pineal gland, a small endocrine gland in the centre of the brain, is stimulated by dim light or the dark – when it will start to release melatonin – and inhibited by light.
人脑部中心松果腺(一种小的内分泌腺)受暗淡气氛或黑夜刺激，褪黑激素开始分泌便产生睡意，光却有阻止作用。
