In blinded Japanese quail (Coturnix coturnix japonica) encephalic photoreception of the stimulus from long photoperiods is sufficient to induce and maintain normal gonadal function in females (egg laying) and in males (enlargement of the cloacal gland). However, the termination of sexual activity by short days is dependent on these birds having experienced long days at the time of blinding.
在经过致盲处理的日本鹌鹑（ Coturnix coturnix japonica ）中，长光照周期刺激的脑部感光作用足以诱导和维持雌性（产卵）和雄性（泄殖腔腺增大）的正常性腺功能。然而，短日照时期终止性活动取决于这些鸟类在致盲时经历过长时间的光照。
