watch According to researchers, a new group of cells in the retina that directly affect the biological clock by sending signals to a region of the brain which regulates our daily (circadian) rhythms, thereby opening a new therapeutic possibilities to manipulate the retina’s signals and alter the body’s responses to light changes.
source site The suprachiasmatic nucleus (SCN) is a region of the brain, which co-ordinates the circadian rhythm using many different signalling molecules, including the neurohormone vasopressin.
