The numbers superimposed on the above brain images are what constitute the
Brodmann's map of cytoarchitectonics. 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]. The following
table provides a general view of brain function that refers to the Brodmann map.
Functional Areas of the Brain
As you may notice, many of the areas that are involved in the same general
cognitive functions are numbered sequentially (or almost). This is no
coincidence. 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. Areas that perform
the same tasks use essentially the same types of cells.
In general, information tends to flow from the back of the brain to the
front. The brain expends most of its energy packaging sensory input from all
available modalities into a coherent view of the environment. Vision is combined
with somatosensory information to give a sense of where one's body is in space.
Memory functions in the temporal lobe allow for recognition of the visual
perceptions. The processed sensory input finally makes its way to the frontal
lobe where decisions are made regarding the various stimuli.
