The genes that control the body clock are most active in parts of the brain called the suprachiasmatic nucleus的復(fù)數(shù)形式）" target="_blank">nuclei. 控制生物鐘的基因在腦部的視交叉上核的細(xì)胞內(nèi)最為活躍。

Initial theories suggested a pathway from the retina to the suprachiasmatic nucleus. 初步理論表明視網(wǎng)膜至視交叉上核間有一通道。
