The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
In terms of Brodmann areas, the extrastriate cortex comprises Brodmann area 18 and Brodmann area 19, while the striate cortex comprises Brodmann area 17. [3]In primates, the extrastriate cortex includes visual area V3, visual area V4, and visual area MT (sometimes called V5), [3] while V1 corresponds to the striate cortex, and V2 to the prestriate cortex.

The subject's task is to make a saccade to the location of the target. Neurons in area LIP have been shown to start responding with the initial presentation of the stimulus. The neurons keep responding through the delay period until the saccadic eye movement starts and the animal soon focuses on the exact location of the previously shown target.
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
The respiratory center is made up of three major respiratory groups of neurons, two in the medulla and one in the pons. In the medulla they are the dorsal respiratory group, and the ventral respiratory group. In the pons, the pontine respiratory group includes two areas known as the pneumotaxic center and the apneustic center.
GABAergic amacrine cells are usually wide field amacrine cells and are found in the ganglion cell layer (GCL) and the inner nuclear layer (INL). One type of GABAergic amacrine cell that is fairly well studied is the starburst amacrine cell.
Brodmann area 8, or BA8, is part of the frontal cortex in the human brain. Situated just anterior to the premotor cortex , it includes the frontal eye fields (so-named because they are believed to play an important role in the control of eye movements). Damage to this area, by stroke, trauma or infection, causes tonic deviation of the eyes ...
