Recent Examples of visual cortex from the Web
As three women spent hours viewing hundreds of short videos, a functional MRI machine measured signals of activity in the visual cortex and elsewhere.
Thinking visually In the visual cortex, different groups of neurons recognize features like edges and surfaces (and others identify motions, which aren't really relevant here).
Because the oscillations are induced visually, the plaque reduction seen by the study is limited to the visual cortex of the brain, and seems to wear off in about a day.
Other theories that have been put forth to explain the perception of motion, include the idea that tiny rapid eye movements cause so many slightly different images to be passed to the visual cortex at once that the brain gets confused.
To test out the device, the team implanted the tiny PRIMA panels in rats, then exposed them to flashes of light, measuring their response by electrodes implanted over the visual cortex—the part of the brain that processes imagery.
The nanowires generate electrical signals that stimulate the undamaged nerve cells adjacent, which send impulses to the visual cortex.
