 The Human Brain
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).
For example, areas of the brain that participate in motor control send more information out to execute its commands than do areas involved in vision, which receive more information than they send out.

That is what the German anatomist Korbinian Brodmann did in the early 20th century, when he developed a map of the brain based on the differences in the cellular architecture of the various parts of the cortex.
For example, Brodmann's area 17, which receives information from a nucleus of the thalamus that is connected to the retina, turns out to correspond precisely to the primary visual cortex.
And Brodmann's area 4, from which the axons of the large pyramidal cells project to the motor neurons of the spinal cord, corresponds broadly to the motor cortex.

There are nine major somesthetic areas within the parietal lobe, such that the primary, association, and assimilation areas actually consist of numerous subareas.
Neurons in area 5 receive information already analyzed in the immediately adjacent primary somesthetic cortices, some cells in the association area (Brodmann's area 5ab) also receive input from the contrateral primary zone (via the corpus callosum) as well as from the motor association areas (area 6) in the frontal lobes (Dong et al.

 BrodmannAreas - Imaging Wiki
Brodmann (1909) classified brain regions based on their cytoarchitecture (basically, the appearance of the cortex under the light microscope).
For example, the 'stripe' of the striate cortex delineates the first main cortical area of the visual system (today this area is usually referred to as V1, Brodmann called it area 17).
However, it is important to remember that Brodmann's Areas (BAs) were identified purely based on visual appearance, which is not necessarily related to function.

Area M corresponds to the anterior projection of the prefrontal dorsolateral area, that is related to superior intelligence.
This area shows a significant difference with diminution during activation P<0.02 at the left and P<0.05 at the right and is related to emotional and neurovegetative situations and is accompanied in borderline patients with anxiety, with symptoms in the abdominal, thoracic region or in areas of visceral content.
Furthermore, this area is rich in connections with the hippocampus structure that appears to be a site of temporal memory, this temporal memory later on transfers to other areas of the cortex for permanent recording (31).
