Visual cortex

Print Advertisement Picture a living thing—say, a dog. Now imagine a hammer. You just activated two different areas of your visual cortex, the brain region that processes eyesight. Thinking of a dog activates an area that deals with animate objects, whereas a hammer excites one that processes inanimate things.

Now a new study shows something surprising: The finding challenges the long-held notion that the two separate processing areas exist solely as the result of learning to recognize the differences in the visual appearance between living and nonliving things, says cognitive neuroscientist Marius Peelen of Princeton University, who was not involved in the study.

That something could be connections to other brain areas, Caramazza suggests. From the visual cortex, information about living and nonliving objects is shuttled to different areas of the brain so as to trigger appropriate reactions.

The new findings suggest that the wiring system that connects different areas of the visual cortex with appropriate regions in the rest of the brain is innate—it does not have to form gradually based on visual inputs.Visual cortex. The primary visual cortex (area V1) is the first stage of visual cortical processing, where neurons are selective for simple stimulus attributes such as orientation.

Studies of the brain mechanisms of cognitive functions (attention, perception, memory, language, and intelligence).

The objective of these studies is to gain better understanding of the dysfunction of the cerebral cortex in neurological and mental illness impairing cognition. The posterior parietal cortex is a portion of the parietal lobe, which manipulates mental images, and integrates sensory and motor portions of the brain..

A majority of experiments highlights a role of human posterior parietal cortex in visual working memory and attention. We therefore have to establish a clear separation of visual memory and attention from processes related to the planning of.

The vast majority of the nerve fibres in the optic tract project to the lateral geniculate nucleus (LGN) in the dorsal part of the thalamus.

The LGN is the main relay in the pathway to the primary visual cortex.
