Clay Reid, who quit a tenured job at Harvard, studies the mouse visual cortex.
FORBES: Inside Paul Allen's Quest To Reverse Engineer The Brain
Looking at faces activates a particular part of the ventral visual cortex called the fusiform face area.
The development of healthy vision, for example, is dependent on being able to see normally in order to develop the visual cortex.
It is here, in the visual cortex, that artists play their games.
The visual cortex is divided into some two dozen areas, but the most thoroughly investigated are those that handle the incoming signal first.
Specialists say out of 30 or so areas in the visual cortex, only one shows any grid-like relationship to something in the real world.
After that, the divided signal is channelled for analysis to the visual cortex, a large, convoluted region at the very back of the brain.
This is a spot which contains some of the nerve tracts that transmit information from the eyes to the visual cortex at the back of the brain.
The study results could help distinguish between normal and abnormal processes within the visual cortex and identify what parts of the brain are targets for the treatment of anxiety disorders.
Nerves from a part of the rat brain known as the basal forebrain are thought to secrete the chemical acetylcholine into the brain's main vision center, also called the primary visual cortex, reinforcing connections that were recently active.

The results suggest that these emotions are handled in the medial prefrontal cortex (the middle of the front of the frontal lobe), the left posterior superior temporal sulcus (one of the furrows towards the side of the brain) and the visual cortex (towards the back of the brain).
Whatever language a person is reading, the same area of inferotemporal cortex, the visual word form area, is activated.
By measuring relative degrees of activation in the parietal lobe, an area involved in integrating visual images, and in the prefrontal cortex, where decision making takes place, Berns says, he could determine that the group changed what the reporter perceived.
