- ... The avian pineal gland, like that of mammals, displays a striking circadian rhythm in the synthesis and release of the hormone melatonin. However, the pineal gland plays a more prominent role in avian circadian organization and differs from that in mammals in several ways. One important difference is that the pineal gland in birds is relatively autonomous. In addition to making melatonin, the avia ...

- ... The suprachiasmatic nucleus (SCN) contains a biological clock that generates timing signals that drive daily rhythms in behaviors and homeostatic functions. In addition to this pacemaker function, the SCN gates its own sensitivity to incoming signals, which permits appropriate temporal adjustment to achieve synchrony with environmental and organismic states. A series of time-domains, in which the ...
