Lateralization of Function in Cerebral Hemispheres

One of the main objectives of lateral neuroscience in brain hemispheric function is to make it possible to understand the relationship between nervous system structure and human outward behavior. In many cases it is difficult or unethical to study the nervous system directly during behavior and you need to use indirect methods. An example of such an indirect method is to use the subject's favorite hand to predict which of the two hemispheres is predominant. His approach to functional facing has some difficulties, but if it can be better understood, it has many practical and theoretical meanings for neuroscience research You may have it.

The brain consists of the left and right half of the cerebral hemisphere. Sideification refers to the positioning of various functions, abilities and skills in either or both of the hemispheres. Specifically, language, writing, logic, and math skills are on the left hemisphere, creativity, fantasy, art, and music skills are on the right hemisphere. Although hemispheres may have different functions, these brain groups mostly work together with their function coordinated.

The brain of the cerebral hemisphere constitutes the largest visual part of the human brain. Various structural combinations including cortex, basal ganglia, amygdala and hippocampus form cerebral hemispheres. Hemispheres control the majority of human brain functions, such as mood, memory, perception, motor function together. In addition, the cerebral hemisphere represents the cognitive ability of the brain. Connecting each hemisphere is a calling body and some additional commissures. One of the most important parts of the cerebral hemisphere is the cortex. It consists of gray matter covering the surface of the brain. Functionally, the cerebral cortex participates in the planning and execution of daily work

The cerebral cortex is the outer surface of the cerebral hemisphere. This is the highest level brain and there are about 20 billion neurons in the human brain to achieve the highest level of mental function. The cerebral cortex is a layer of gray matter about 1/2 cm thick. Figure 3-2d shows the cross section of the cerebral hemisphere and the cortex is shown as a pink layer on its outer surface. Figure 4-2d shows the very enlarged part of the cortex. It is dyed with stains and dyes only neurons and colloidal blue cells. This shows that dense neurons form six layers, each with different functions and connections.
