The visual system as economist: Neural resource allocation in visual adaptation

(Medical Xpress)—It has long been held that in a new environment, visual adaptation should improve visual performance. However, evidence has contradicted this expectation: Adaptation sometimes not only ...

Reward linked to image is enough to activate brain's visual cortex

Once rhesus monkeys learn to associate a picture with a reward, the reward by itself becomes enough to alter the activity in the monkeys' visual cortex. This finding was made by neurophysiologists Wim Vanduffel and John Arsenault ...

Seeing is as seeing does: Spatially-structured retinal input in early development of cortical maps

(Medical Xpress) -- Remarkably, cortical maps show that neurons in the primary visual cortex have specific preferences for the location and orientation of a given visual field stimulus – but how these ...

Human attention to a particular portion of an image alters the way the brain processes visual cortex responses to that i

Our ability to ignore some, but not other stimuli, allows us to focus our attention and improve our performance on a specific task. The ability to respond to visual stimuli during a visual task hinges on altered ...

Neural balls and strikes: Where categories live in the brain

Hundreds of times during a baseball game, the home plate umpire must instantaneously categorize a fast-moving pitch as a ball or a strike. In new research from the University of Chicago, scientists have pinpointed an area ...
