Which of the following centers are involved in maintaining the circadian rhythm?
The entrainment process in most cases is dependent on the suprachiasmatic nuclei (SCN) located bilaterally above the optic chiasma. Efferents from the SCN initiate neural and hormonal signals that enteain a wide variety of well known circadian rhythms including the sleep wake cycle and the secretion of the pineal hormone melatonin.
Supraoptic nuclei
Posterolateral nuclei
Ventrolateral nuclei
