How is night vision maintained during retinal disease?

September 24, 2020

New research from the University of Utah provides insight on how people with retinal degenerative disease can maintain their night vision for a relatively long period of time.

The columns are formed by stacking images taken at 5-micron increments through a millimeter of depth in each of the regions. Credit: Sur Lab/MIT Picower Institute

Live imaging method brings structural information to mapping of brain function

Real neurons are noisy. Can a retinal prosthetic figure that out?

September 16, 2020

The brain’s visual centers must be adept at filtering out noise from retinal cells to get to the true signal, and those filters have to constantly adapt. Prosthetic retinas are going to need this same filtering to succeed, NEI-funded research shows.
