  Brodmann x Function
Brodmann mapped the cortex according to types of neurons and their density in different cortical layers.
Further suppose that the exclusivity assumption is violated, and that the functions are implemented in overlapping brain regions: A depends on areas 1 and 2; B depends on areas 1 and 3; C depends on areas 2 and 3.
Conversely, the typical Brodmann area is differentially engaged in 40% of behavioral (cognitive, perceptual, emotive) domains.

  Brodmann area 47 - Wikipedia, the free encyclopedia
Brodmann area 47, or BA47, is part of the frontal cortex in the human brain.
It is inferior to areas BA10 and BA45, and lateral to BA11.
Cytoarchitectonically it is bounded caudally by the triangular area 45, medially by the prefrontal area 11 of Brodmann-1909, and rostrally by the frontopolar area 10 (Brodmann-1909).

 BASIC CEREBRAL CORTEX FUNCTION OTHER THAN VISION
Brodmann area 42 is the auditory association cortex which probably includes among its functions the discrimination of sequences of sound patterns.
Since virtually all sensory areas are posterior to the central sulcus, areas not devoted to primary sensation in the temporal, parietal and occipital lobes are regarded as "sensory association cortex".
Brodmann area 18 is regarded as a secondary sensory area concerned with the elaboration and synthesis of visual information.

 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).
Areas that perform the same tasks use essentially the same types of cells.

In the human brain, however, area 11 was used loosely by Brodmann to refer to the entire orbital frontal cortex (except for the orbital extension of the ventrolateral frontal cortex).
Brodmann's parcellation was adopted in the Talairach and Tournoux stereotaxic atlas (24), which is commonly used in the functional neuroimaging field.
However, the human orbital frontal cortex that Brodmann referred to globally as area 11 is not cytoarchitectonically homogeneous and has recently been subdivided into different architectonic areas that correspond to areas 13, 14, and 11 of the orbital frontal cortex of the macaque monkey (45).

In describing two areas as functionally coupled, we imply that the two regions some how work together, influence each other, or are commonly influenced by another source, without indicating the source or causality of their functional connection.
In this approach, functional connectivity is operationally defined as the extent to which activity in one area of the brain is covariant with activity in another area of the brain across subjects.
Two areas involved in reading may be correlated highly in both conditions, but if their activity is not modified proportionally by the addition of speaking aloud, they will show little between-task correlation.

 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.

While there were trends for ecstasy users to have lower FDG uptake in various areas (cingulate, Brodmann's area 11) and higher uptake in one area (Brodmann area 10), these differences were all non-significant.
Cumulative ecstasy use was unrelated to FDG uptake in cingulate, putamen, caudate, amygdala, hippocampus, Brodmann area 10 (all areas examined in correlational analyses).
While FDG uptake differed in other areas, these differences did not reach statistical significance, and there was no single brain area whose FDG uptake distinguished all ecstasy users from all controls.

Specifically, the inferofrontal cortex (Brodmann area 11) and the amygdala registered the highest interindividual variability at this dose, with the individual binding values ranging from 31 to 61% and from 20 to 52% below the placebo condition for those two regions, respectively.

This work suggested to us that bilateral removal of analogous areas from the cortex of psychotic patients might well result in specific behavior changes which would be of benefit to the patient.
No attempt was made in this series to ablate area 9 in its entirety owing to the proximity of its caudal margins to the motor and speech areas.
Richter and Hines, in discussing changes following removal of area 9, state that "the increased activity may be regarded as a result of a release phenomenon, i.e., the removal of the inhibitory influence from the higher centers may permit external stimuli to pass on freely without hindrance or interference to lower reflex centers.
