  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 all cases this was confirmed by correlation to Brodmann's areas using the stereotactic atlas of Talairach and Tournoux; allowances were made for individual variations from the idealized atlas brain, usually of the order of ± 5 mm, and for visible distortion, if any, caused by the mass of the lesion seen on MR imaging.
The anterior speech area (Broca's area) resides within the third frontal convolution in Brodmann's areas 44 and 45.[14,16] The frontal lobe beyond areas 44 and 45 is also the seat of some aspects of language.
For the concept of cortical reorganization due to the occupation by an AVM of the area in which a particular function is known to reside to be validated, a specific function must be demonstrated to reside outside of its usual Brodmann area.

Encoding: In comparison to the memory-impaired TBI group, normal memory subjects demonstrated significantly greater activation in medial frontal regions including anterior cingulate cortex (Brodmann areas 24 and 32) and medial frontal gyrus (Brodmann area 9).
Retrieval: In comparison to the memory-impaired TBI group, normal memory subjects demonstrated significantly greater activation in the inferior frontal gyrus (Brodmann area 47), the anterior cingulate cortex (Brodmann areas 24 and 32) and medial frontal gyrus (Brodmann area 9), regions that have been associated in past studies with retrieval success.
By contrast, the memory impaired TBI cohort demonstrated relatively greater reliance on a posterior activation pattern during retrieval, with significantly greater activation in the posterior cingulate gyrus (Brodmann area 31), a region that has been associated in past studies with both retrieval effort and success.

He regarded the frontal area as particularly necessary for the formulation of the intention to say things.
The investigation of inferior premotor and frontal area lesions primarily involves tasks that require the patient to reproduce a story, describe a previous experience, make up a story on a given theme, or put together a story using ready-made sentences provided by the examiner in written form.

However, this area is agranular, whereas area 44 (Broca's area) in the human brain is a dysgranular architectonic entity that lies rostral to the ventral agranular premotor cortex.
Such an area should have the following three properties: first, it should exhibit the key architectonic characteristics of area 44 of the human brain; second, it should be bounded topographically by the same architectonic areas as in the human brain; and third, it should be involved, at least, with the orofacial musculature.
Area 44 in the monkey lies rostral to the convexity of the premotor cortex where the mirror neurons were recorded (area F5c).

Broca's area is the section of the human brain (in the opercular and triangular sections of the inferior frontal gyrus of the frontal lobe of the cortex) that is involved in language processing, speech production and comprehension.
It can also be described as Brodmann's Area 44, and 45 and is connected to Wernicke's area by a neural pathway called the arcuate fasciculus.
PET and functional MRI have found decreases in activity in the Broca's area in stuttering.There is greater activation of the right hemisphere homologue of the Broca's area (area of Ross)which is believed to be a compensatory response to the hypoactivity in the Broca's area proper.

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.

These areas show the difference in frontal activation between patients with silent ischemia and those with angina pectoris and the difference in the time course of activation between the frontal areas and the thalami.
Thus, the regional cerebral blood flow changes in Brodmann area 24 and Brodmann area 10 during myocardial ischemia are significantly greater in patients with angina pectoris than in patients with silent ischemia.
Although the regional cerebral blood flow increases in Brodmann area 24 and Brodmann area 10 entirely resolved by the baseline 3 scan, thalamic regional cerebral blood flow remained increased in both patient groups during the scan done after ischemia.
