The visual cortex’s primary aim is to acquire, categorize, and incorporate visual information. When visual data is sent forward from the retina, it travels through the use of the optic nerve (that shortly becomes the optic tract) to the lateral geniculate nucleus of the thalamus.
The primary visual cortex (V1) is located in and around the calcarine fissure in the occipital lobe. Each hemisphere's V1 receives information directly from its ipsilateral lateral geniculate nucleus that receives signals from the contralateral visual hemifield.
The anatomy of the primate primary visual cortex has been worked out in great detail. The three basic organizing principles of primate V1 are the: 1) laminar and 2) columnar arrangement of excitatory and inhibitory neurons (an arrangement shared with other neocortical areas) and 3) the regular spacing of anatomical/functional compartments ...
The primary purpose of the visual cortex is to receive, segment, and integrate visual information. The processed information from the visual cortex is subsequently sent to other regions of the brain to be analyzed and utilized.
What is the primary visual cortex and what does it do? The primary visual cortex, often called V1, is a structure that is essential to the conscious processing of visual stimuli.
The primary visual cortex, also called visual area 1 (V1), striate cortex, or area 17, is the best-studied cortical area and so has been the primary source of knowledge of cortical neurons and circuits. As with the rest of the neocortex, the visual cortex is composed of six distinct layers.
Typically based on the function and structure, the visual cortex is divided into five areas (v1-v5). The primary visual cortex (v1, BA 17) is the first area that receives the visual information from the thalamus, and its located around the calcarine sulcus.
