Melatonin is a hormone substance that lightens the color of skin pigments at levels that vary with time of day. A third type of photoreceptor cell, the very rare "retinal specialized photoreceptor ganglion cells" (iprgcs), exists on the retina of mammals where ganglion cells can directly sense light. It contains a newly discovered photoprotein, the nigra, which produces a series of chemical reactions to light, causing the iPRGC cells to discharge under light. This cell does not form vision, but is directly transmitted to the suprachiasmatic nucleus (SCN) of the Hypothalamus (hypothioanalus) via the optic nerve, and is involved in regulating the circadian rhythm. Photoreceptors are linked to the biological clock in the human brain, and their light reception suppresses melatonin secretion from the pineal gland. Melatonin is also called sleep hormone, when the amount of melatonin in a human body reaches a certain amount, the human body feels tired and sleepy, and the melatonin is secreted to prolong the deep sleep stage and improve the sleep quality.
