visual cortex

AREA 25 - This region is particularly implicated in the normal processing of sadness.

The visual dorsal stream (green) and ventral stream (purple) are shown. The ventral stream is responsible for color perception.

Psychologists Link Emotion to Vividness of Perception and Creation of Vivid Memories - Psychologists overlaid images with visual noise to measure perception. After accounting for other features of images that contribute to perceptual vividness, such as contrast, color, and scene complexity, they found emotionally arousing images to be perceived more vividly, and thus contributing partly to more vivid memories of certain images later.

Module 4. "Types of anopsias (visual field defects) and corresponding anatomical insults." Note that anything behind the chiasm gives a homonymous defect (anything along the optic tract, LGN, optic radiations, or visual cortex).

' Psychologists have designed an experiment to investigate whether human vision is more sensitive during physical activity. The researchers found that low-intensity exercise boosted activation in the visual cortex, the part of the cerebral cortex that plays an important role in processing visual information. Their results appear in the Journal of Cognitive Neuroscience.'  Your brain on exercise:

Princeton University researchers have found that the pulvinar, a mysterious region deep in the human brain, acts like a switchboard operator to make sure that separate areas of the brain are communicating about the same external information most important to our behavior at a given moment. The pulvinar uses electrical impulses to synchronize and allow more effective communication between brain cells in the visual cortex, which processes visual information.

Do our brains blink? The research says that our brains do, in fact, "blink," every time we shift our attention!  When we shift our attention from one object to another, the activity of the neurons in the visual cortex (the part of the brain that processes visual information) is temporarily disrupted. https://mybrainware.com/neuroscience-network-news/ for more info.
