The Science of Light And Perception
1:32:12 - 1:40:55 (08:42)
A discussion of the different types of neurons in our eyes and how they respond to light, particularly blue and green light, and how this can affect our perception of our surroundings.

Summary
This episode talks about how aura and photophobia occur and also a well-established way to offset photophobia, which can be experienced with or without an intense headache. People will see a kind of halo of light, or they'll feel that the light around them is surrounding their body or some other object they're looking at when aura and photophobia occur.

Bright blue and green light activates intrinsically photosensitive ganglion cells in the eye which then activate the lateral posterior neurons, including those in the central circadian clock which sets our sleep and wake rhythms.

Summary
Bright blue and green light activates intrinsically photosensitive ganglion cells in the eye which then activate the lateral posterior neurons, including those in the central circadian clock which sets our sleep and wake rhythms. These cells respond most robustly to bright blue or green light, whether it's from sunlight or artificial sources.
