 Korbinian Brodmann - Wikipedia, the free encyclopedia
Korbinian Brodmann (November 17, 1868 - August 22, 1918) was a German neurologist who became famous for his definition of the cerebral cortex into 52 distinct regions from their cytoarchitectonic (histological) characteristics.
Some of these areas were later associated to nervous functions, such as areas 41 and 42 in the temporal lobe (related to hearing), areas 1, 2 and 3 in the postcentral gyrus of the parietal lobe (the somatosensory region), and the areas 17 and 18 in the occipital lobe (the primary visual areas).
Brodmann studied medicine in Munich, Würzburg, Berlin and Freiburg, where he received his medical diploma in 1895.

Brodmann assigned numbers to various brain regions by analyzing each area's cellular structure starting from the central sulcus [the boundary between the frontal and parietal lobes].
As you may notice, many of the areas that are involved in the same general cognitive functions are numbered sequentially (or almost).
Areas that perform the same tasks use essentially the same types of cells.

 Reasoning Errors In The Current Models of Human Cognition
In most of areas of research, it is possible to take for granted that the model space is small, but this is not true when dealing with models of human thinking.
For example, even though the size of Brodmann's area 17 (now called V1) can vary from one individual to the next by 2- to 3-fold (3, 5), area 17 (V1) is always next to area 18 (V2) and never has area 19 (V3) as a nearest neighbor.
Area 18 is around area 17 by definition, so it is stupid to wonder why it is always there.

The optic tract fibres make synapses with nerve cells in the respective layers of the lateral geniculate body, and the axons of these third-order nerve cells pass upward to the calcarine fissure (a furrow) in each occipital lobe of the cerebral cortex.
This area is called the striate area because of bands of white fibres—axons from nerve cells in the retina—that run…

Photoreceptor cells (rods and cones) act as transducers to convert the light signals into electrical signals, further processed by other neurones in the retina: bipolar cells, horizontal cells, amacrine cells, retinal ganglion cells, and interplexiform cells.
The action potentials generated are transmitted via the optic nerve (cranial nerve II) to - chiefly - the lateral geniculate nucleus (visual information), superior colliculus (somatic reflexes), and pretectal areas (autonomic reflexes).
The lateral geniculate nucleus projects to the the primary visual cortex of the occipital lobe (calcarine cortex, striate cortex, or Brodmann's area 17); the final area of neural processing of visual information.

These nuclei then send projections via the lateral lemniscus to the inferior colliculus which is located superior to the aqueduct in the midbrain.
The inferior colliculus in turn projects to the medial geniculate nucleus, which some authors consider to represent part of the thalamus, and finally to the primary auditory cortex which is located in the superior temporal cortex, also known as Brodmann area 41 and 42.
After the neurons of the lateral geniculate are stimulated they send axonal projections via the optic radiations to the primary visual cortex around the calcarine fissure in the occipital lobe, which is also known as Brodmann area 17.
