Explain the process by which light acts on the suprachiasmatic nucleus (SCN) to control the circadian rhythm
What will be an ideal response?
Answer: The SCN receives afferent signals from the retina (melanopsin in ganglion cells) that provide the capacity of light signals to reset the SCN clock (zeitgeber function). Glutamate is the transmitter between retinal cells and the SCN. The output of the SCN is to three nearby brain regions that in turn interact with neural circuits that induce wakefulness or promote sleep.
