A Brodmann area is a region in the brain cortex defined in many different species based on its cytoarchitecture. Cytoarchitecture is the organization of the cortex as observed when a tissue is stained for nerve cells. Brodmann areas were originally defined by Korbinian Brodmann and referred to by numbers from 1 to 52. Some of the original areas have been subdivided further and referred to, e.g., as "23a" and "23b". The same number in different species does not ... Including:

Visual cortex is the term applied to both the primary visual cortex (also known as striate cortex or "V1") and upstream visual cortical areas also known as extrastriate cortical areas (V2, V3, V4, V5). The primary visual cortex is anatomically equivalent to Brodmann area 17, or BA17. Brodmann areas are based on a histological map of the human brain created by Korbinian Brodmann. The visual cortex occupies about one third of the surface of the cerebral cortex in humans. It is thou ... Including:

Brodmann area 6, or BA6, is part of the frontal cortex in the human brain. Situated just anterior to the primary motor cortex (BA4), it is sometimes called premotor cortex. The medial part of BA6 is also referred to as supplementary motor area. This large area of the frontal cortex is believed to play a role in the planning of complex, coordinated movements. Brodmann area 6 is also called agranular frontal area 6 in humans because it lacks in internal granular cortical layer (layer IV). It is a subdivision of the cytoarc ...

Visual area V2 is the second major area in the visual cortex, and first region within the visual association area. It receives strong feedforward connections from V1 and sends strong connections to V3, V4, and V5. It also sends strong feedback connections to the V1. Anatomically, V2 is split into four quadrants, a dorsal and ventral representation in the left and the right hemispheres. Together these four regions provide a complete map of the visual world. Functionally, V2 has many properties in common with V1. Cells are tuned ...

Visual area V5, also known as visual area MT (middle/medial temporal), is a region in the extrastriate cortex that appears to process complex visual motion stimuli. It contains many neurons selective for the motion of complex visual features (line ends, corners). Much work has been carried out on this region as it appears to integrate local visual motion signals into the global motion of co ...

Visual area V4 is one of the visual areas in the extrastriate visual cortex of the macaque monkey. It is located anterior to V2 and posterior to visual area PIT. It comprises four separate regions (left and right V4d, left and right V4v). It is unknown what the human homologue of V4 is, and this issue is currently the subject of much scrutiny. V4 is the third cortical area in the ventral stream, receiving strong feedforward input from V2 and sending strong connections to the posterior inferotemporal cortex (PIT). It also receiv ...

The primary visual cortex is the most well-studied visual area in the brain. It is the part of the cerebral cortex that is responsible for processing visual stimuli. It is the simplest, earliest cortical visual area. It is highly specialized for processing information about static and moving objects and is excellent in pattern recognition. The functionally defined primary visual cortex is approximately equivalent to the anatomically defined striate cortex. The name "striate cortex" is derived from the stria of Gennari ...

Ancient Greeks had differing views on the function of the brain. Hippocrates believed the brain to be the seat of intelligence. Aristotle believed that the brain was a cooling mechanism for the blood while the heart was the seat of intelligence. He reasoned that humans are more rational than the beasts because they have a proportionally larger brain to cool their hot-bloodedness
