  Brodmann area 23 - Wikipedia, the free encyclopedia
Cytoarchitecturally it is bounded dorsally by the dorsal posterior cingulate area 31, rostrally by the ventral anterior cingulate area 24, and ventrorostrally in its caudal half by the retrosplenial region (Brodmann-1909).
Brodmann area 23 is a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture.
Brodmann regarded it as topographically and cytoarchitecturally homologous to the combined ventral posterior cingulate area 23 and dorsal posterior cingulate Brodmann area 31 of the human (Brodmann-1909).

 Brodmann area 7 - Wikipedia, the free encyclopedia
Situated posterior to the primary somatosensory cortex (Brodmann areas 1, 2 and 3), and superior to visual cortices (Brodmann areas 17, 18 and 19), this region is believed to play in visuo-motor coordination (e.g., in reaching to grasp an object).
Brodmann area 7 is a subdivision of the cytoarchitecturally defined parietal region of cerebral cortex in the guenon.
Distinctive features (Brodmann-1905): in area 7 compared to Brodmann area 5-1909, large ganglion cells are absent from the internal pyramidal layer (V); the pyramidal cells of the external pyramidal layer (III) sublayer 3b are, on average, larger; the multiform layer (VI) is denser and narrower and more sharply bounded by subcortical white matter.

 Primary motor cortex - Wikipedia, the free encyclopedia
There is a precise somatotopic representation of the different body parts in the primary motor cortex, with the leg area located close to the midline, and the head and face area located laterally on the convex side of the cerebral hemisphere (motor homunculus).
In humans, the lateral area of the primary motor cortex is arranged from top to bottom in areas that correspond to the buttocks, torso, shoulder, elbow, wrist, fingers, thumb, eyelids, lips and jaw.
Pre-motor areas are involved in planning actions (in concert with the basal ganglia) and refining movements based upon sensory input (this requires the cerebellum).

Broca's area (Brodmann areas 44 and 45) is in the inferior aspect of the premotor area, or the frontal operculum.
It also may be caused by a lesion that isolates Broca's area from the frontal heteromodal cortex, such as infarction of the border zone between areas perfused by the anterior and middle cerebral arteries.

 Brain - Wikipedia, the free encyclopedia
The space between neurons is filled with dendrites as well as unmyelinated segments of axons; this area is referred to as the neuropil.
Injuries to the brain tend to affect large areas of the organ, sometimes causing major deficits in intelligence, memory, and movement.
Similarly, a positron emission tomography (PET), is able to monitor glucose metabolism in different areas within the brain which can be correlated to the level of activity in that region.

Areas of significant change not seen in experiment 2 included decreases in the right temporal cortex (Brodmann area 37) and bilateral inferior frontal cortex (Brodmann area 10/47), as well as increases in the cerebellar vermis and right premotor cortex (Brodmann area 6).
In addition, changes in these same areas were observed with the resolution of negative mood symptoms in the second experiment, even though tearfulness was not observed in any of the patients during either scan.
The two areas demonstrating the greatest magnitude of change, subgenual cingulate (Brodmann area 25) and right prefrontal cortex (Brodmann area 9), were also strongly intercorrelated.

 The neurology of syntax: Language use without Broca's area
One, subserving the perception of spoken language, occupies the posterior-superior temporal area (the posterior portion of area 22) and Heschl's gyrus (areas 41 and 42); Wernicke's area comprises the posterior part of area 22 and the parietotemporal junction.
The third area situated at the posterior end of the inferior frontal convolution is referred to as Broca's area or Brodmann's area 44 and is concerned with the motor aspects of speech.
The question, obviously, is whether or not this area supports a device dedicated to syntactic analysis of transformationally moved constituents, and if so, what this device is. One possibility is that the comprehension deficit follows from a general disruption to "working memory", not from a language mechanism.

Even today it forms the basis for so-called "localisation" of function in the cerebral cortex, and Brodmann's "areas" are still used to designate functional regions in the cortex, the part of the brain that brings the world that surrounds us into consciousness.
Indeed, Brodmann's famous "maps" of the cerebral cortex of humans, monkeys and other mammals must be among the most commonly reproduced figures in neurobiological publishing.
As Laurence Garey, too, used Brodmann’s findings and maps in his neurobiological work, and had the good fortune to have access to a copy of the book, he decided to read the complete text and soon discovered that this was much more than just a report of laboratory findings of a turn-of-the-twentieth-century neurologist.

The neuroanatomist Korbinian Brodmann subdivided the human brain into 52 "areas" based on the underlying cytoarchitecture.
Now, a team of German neuroscientists have examined Brodmann's area 22--a morphological correlate to "Wernicke's area" known to be important for speech comprehension--and have shown that the left (language dominant) and right hemispheres have different patterns of local connectivity in post-mortem human brain tissue.
This article reviews the debate over the evolution of language and to suggest some keys to its resolution by examining some of the theoretical and empirical evidence for the innateness of language that has caused renewed interest in the evolution of language.

 Musical syntax is processed in Broca's area: an MEG study - Nature Neuroscience
The source of mERAN activity was localized in Broca's area and its right-hemisphere homologue, areas involved in syntactic analysis during auditory language comprehension.
We find that these areas are also responsible for an analysis of incoming harmonic sequences, indicating that these regions process syntactic information that is less language-specific than previously believed.

This comparison will determine if the localized areas of control are the same and, if not, how they differ.
In part this is due to the fact that there are significantly different areas of neuronal activity involved in a short period of time producing non-stationary distributed sources.
The extent to which specific cerebral regions are involved during these tasks will be quantified using the amplitude and latencies of the evoked MEG responses.
