Dr. Satchidananda (Satchin) Panda is a professor in the Regulatory Biology Laboratory at the Salk Institute for Biological Studies. In this video we discuss... The fascinating history of experimentation that ultimately elucidated the location for the region of the brain necessary for a properly timed sleep-wake cycles. The relationship between our body's "master clock" and it's many peripheral clocks. Why infants sleep so intermittently, instead of resting for a longer, sustained duration like healthy young adults... and why this sustained rest also goes haywire in the elderly. The fascinating work Dr. Panda took part in that lead to the discovery of a specialized light receptor in the eye that sets circadian rhythms and is known as melanopsin. The important relationship between the relatively light insensitive melanopsin, which requires around 1,000 lux of light to be fully activated, and its control of the circadian clock by means of activation of the suprachiasmatic nucleus and suppression of melatonin.
