将松果体组织移植到眼睛前房，可以迅速恢复节律性松果体切除麻雀的节律性，并将供体鸟节律的相位转移到宿主身上。因此，移植的松果体不仅允许表达节律性，而且还传递了一种控制昼夜节律系统剩余部分的振荡，并恢复了自我维持节律性的能力。在长期的记录中，麻雀暴露在不同的光照条件下，显示出正常鸟类和接受松果体移植的鸟类的昼夜节律非常相似。
Transplantation of pineal tissue into the anterior chamber of the eye rapidly reestablishes rhythmicity in arhythmic pinealectomized sparrows and also transfers the phase of the donor bird's rhythm to the host. Thus, the transplanted pineal does not merely permit rhythmicity to be expressed but rather transfers an oscillation that controls the remainder of the circadian system and restores the capacity for self-sustained rhythmicity. Long-term recordings, during which sparrosw were exposed to various lighting conditions, demonstrate a remarkable similarity between the circadian system in normal birds and that in birds bearing pineal transplants.
