What are the functions of gray matter?
As part of the central nervous system, gray matter is made of cellular bodies, specifically from cellular bodies of neurons, neurophilic, glial cells and dendrites. Unlike white matter, this type of brain is in the brain areas that include muscle control. It is also among the brain regions that control human perceptions such as how things can be seen or heard or created memories. Speech and emotions are largely influenced by gray matter.
Gray matter is found in several areas of the brain. You can find it on the surface of the cortex and the cerebellum. This type of matter is also located deep in the brain. In the middle of the spinal cord can be found gray and white, but gray prevails. This information is then transferred to the brain areas that process sensory information. Intelligence and skill are often attributed to this brain, mainly because it covers so much brain. In addition, studies have shown that each person has a different amount and density of this brain matter, often show a higher conCentration in areas related to specific intellectual aspects or skill mastery.
previous studies suggest that the size of a human brain has no relation to the level of intelligence. While larger -size brains were present in subjects with higher intelligence results (IQ), increased IQ was not sufficiently significant. Newer research has shown that IQ testing can activate multiple areas of gray matter in the brain. This means that although one can show strengths and weaknesses in specific areas of intelligence, the strengths and weaknesses stem from the combined volume and the level of activity through the individual material formula throughout the bdéště.
Although greater gray matter concentrations can indicate intelligence and skills, small concentrations and deficiencies can lead to problems. For example, in older people, the studies have shown that short -term memory is affected because the volume of gray matter decreaseswith aging. Studies have also shown that the differences in the volume of gray matter can also be associated with certain psychological disorders such as bipolar disorder. In some psychological disorders, evidence may show that patients may have a lack of gray matter in the left parietal lobe. However, the severity and duration are often determined by the volume of matter in the right frontal gyrus section of the brain.
