Scientists Uncover How Decisions About What We See are Relayed Back Through the Brain

Researchers at the National Institutes of Health and the University of Maryland have discovered that decisions based on visual information, which involve a complex stream of data flowing forward and backwards along the brain’s visual pathways, is broadcast widely to neurons in the visual system, including to those that are not being used to make the decision. Feedback—such as information about a decision traveling back to neurons detecting visual features like color or shape—is thought to help the brain focus on visual information that is relevant to decision-making. The study, including Biology Associate Daniel Butts, was published in Nature Communications
