The Importance of Melanopsin Ganglion Cells for Sleep and Overall Health
23:31 - 34:24 (10:53)
Melanopsin ganglion cells present in the retina are responsible for setting the circadian clock, responding to blue and yellow light, and communicating with the brain about the qualities of light present in the environment. Lack of exposure to sunlight during early morning and early evening can severely disrupt sleep rhythms, mood, hormones, metabolism, pain threshold, and the ability to learn and remember information.

Our eyes have a blind spot where the wires of our retinal ganglion cells exit the back of the eye, which is filled in by the positioning of our eyes in our head.

Summary
Our eyes have a blind spot where the wires of our retinal ganglion cells exit the back of the eye, which is filled in by the positioning of our eyes in our head. This part of our vision has the highest acuity and is responsible for our central vision.

The brain can repurpose areas that process one sense to process another sense, an ability known as sensory substitution, which can be used to improve both conscious and subconscious aspects of vision, as well as other senses for those with impairments.

Summary
Melanopsin ganglion cells in the human retina are responsible for setting the circadian clock and responding to blue and yellow light. By not getting sunlight exposure in the early morning and evening, it can severely disrupt multiple factors including sleep, mood, hormones, and more.
