光刺激以多种方式影响动物的功能和行为。根据Wurtman(1)的分析，光信息在哺乳动物中至少有三种功能：1)作为复杂视觉现象的刺激，2)调节视自主反射，3)控制某些“神经植物功能”，如性腺成熟和某些内分泌节律。环境光周期参与大鼠性发育的调控(2)。昼夜和季节的光变化可以同步，甚至产生内分泌功能的节律，如生殖激素周期。节律的起源和持续在许多情况下依赖于反馈机制，包括性腺激素和下丘脑和垂体血管连接。脑下垂体和性腺激素是否与光感受器——眼睛有直接的反馈作用，目前尚不清楚。
Photic stimuli influence the function and behavior of animals in a number of ways. As analyzed by Wurtman (1), photic information serves at least three functions in mammals: 1) it acts as a stimulus for the complex phenomenon of vision, 2) it regulates optic autonomic reflexes, and 3) it controls certain “neurovegetative functions”, such as gonadal maturation and some endocrine rhythms. Environmental photoperiodicity participates in the regulation of sexual development of the rat (2). Diurnal and seasonal photic changes can synchronize, or even generate, rhythms in endocrine function, such as reproductive hormone cycles. The origin and continuation of the rhythms are dependent in many instances on feedback mechanisms involving gonadal hormones and hypothalamic and pituitary vascular connections. Whether pituitary glands and gonadal hormones have feedback functions directly with the photoreceptor organ, the eye, is unknown at this time.
