What is the function of the visual cortex?
Also question is, how does the visual cortex work?
Visual perception begins as soon as the eye focuses light onto the retina, where it is absorbed by a layer of photoreceptor cells. These cells convert light into electrochemical signals, and are divided into two types, rods and cones, named for their shape.
Beside above, what happens when the visual cortex is damaged? Destruction of the primary visual cortex leads to blindness in the part of the visual field that corresponds to the damaged cortical representation. The area of blindness – known as a scotoma – is in the visual field opposite the damaged hemisphere and can vary from a small area up to the entire hemifield.
Hereof, what is the function of the visual association area?
For example, the visual association area on the lower part of the temporal lobe plays a primary role in your ability to recognize faces, dogs, cars, trees, etc., whereas the primary visual cortex is required for detecting basic features of the visual world: edges, light and dark, location, etc.
Where is the visual cortex of the brain?
Also known as the striate cortex, or simply V1, the primary visual cortex is located in the most posterior portion of the brain's occipital lobe . In fact, a large part of the primary visual cortex cannot be seen from the outside of the brain, because this cortex lies on either side of the calcarine fissure.
