On the left side of the brain is an area called Brodmann’s area 22, that help generate and help the understanding of individual words, and on the right side of the brain it helps tell the difference between melody, pitch, and sound intensity. A experiment was taken in early 2000 involving the left side of six men and women’s brains who died within 18-24 hours. What was revealed was that neuron clusters from each side of the brain was similar in size; however, they found that the distance between the clusters on the left side were about 20 percent farther apart, and had more fiber connections among the cells, also it had a more complex cellular structure. Researchers believe this is why that part of the brain (Brodmann’s area 22) is active in processing language.
Meaning
Assistant professor of psychology at the University of Michigan, Jeffrey Hutsler, said "This study clearly shows that an area associated with speech processing differ from the same area on the other side of the brain.
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'sarea 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.
In particular the equivalents in the monkey of Brodmann'sarea 44 - the posterior part of classical Broca's area - and the immediately posterior area 6 have been clearly implicated in mastication,(Luschei and Goldberg, l981) and electrical stimulation of area 6 in humans evokes chewing movements (Foerster, l936).
While this area has not been implicated in vocal communication in monkeys, it is consistently activated in brain imaging studies of speech, (Roland, l993) and, it is active even when the subjects merely think about making movements (Orgogozo and Larson, l979).
It was given equal status with Broca's and Wernicke 's areas as a language area in the classic monograph of Penfield and Roberts (l959).
