How the Brain Fills In the Blind Spot

The blind spot is a gap in vision created by the retina and optic nerve. The retina contains light-sensitive cells that detect light and send signals to the brain through the optic nerve, a bundle of neural fibers. In each retina, there is one area in the periphery where these outputs collect and the optic nerve exits. That ...

To understand how the brain creates a perceptual experience?a representation of a person?s surroundings that involve sights?researchers may study an area in the visual field called the blind spot.

Normally, light reflected off of objects enters the eye, and is focused on the retina?a piece of neural tissue positioned at the back?where phot...
