Neuroscientists discover new factors behind better vision

London, Jun 13 (Prensa Latina) Neuroscientists from New York University have found new factors behind better vision between brain structure and behavior, the British journal Nature Communications reported on Monday.

The size of our primary visual cortex and the amount of brain tissue we have dedicated to processing visual information at certain locations of visual space can predict how well we can see, a team of neuroscientists said.

“By showing that individual variation in the structure of the human visual brain is linked to variation in visual functioning, we can better understand what underlies differences in how people perceive and interact with their visual environment.”

As with fingerprints, the bumps and grooves on each person´s brain surface are unique. However, the significance of these differences is not fully understood, especially when it comes to their impact on behavior, such as distinctions in our ability to see.

This is because V1 has more tissue dedicated to the center of our field of view. Likewise, V1 also enlarges locations to the left and right of where our eyes are fixating relative to locations above or below, again because of differences in the arrangement of cortical tissue.

The primary cortical region of the brain that receives, integrates, and processes visual information transmitted from the retinas is known as the visual cortex. It is located in the occipital lobe of the primary cerebral cortex, which is in the most posterior region of the brain. The visual cortex divides into five different areas (V1 to V5) based on function and structure, with V1 being the primary visual cortex.
