What Is White Matter In Psychology?

by | Last updated on January 24, 2024

, , , ,

White matter is made

up of cells that transmit brain signals from one region of the cerebrum to another

, or from the cerebrum to the lower brains centers. White matter is primarily associated with processing and cognition and acts as a relay between the different regions of the brain.

What does the white matter of the brain do?

White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). … Also, it

improves the speed and transmission of electrical nerve signals along extensions of the

nerve cells called axons.

What is grey matter in psychology?

Grey matter is

made up of neuronal cell bodies

. The grey matter includes regions of the brain involved in muscle control, sensory perception such as seeing and hearing, memory, emotions, and speech.

What is the role of gray matter and white matter?

The gray matter is

the areas where the actual “processing” is done

whereas the white matter provides the communication between different gray matter areas and between the gray matter and the rest of the body. The neurons in the gray matter consist of neuronal cell bodies and their dendrites.

What is an example of white matter?

The white matter of your brain and spinal cord is composed

of bundles of axons

. These axons are coated with myelin, a mixture of proteins and lipids, that helps conduct nerve signals and protect the axons. White matter’s job is to conduct, process, and send nerve signals up and down the spinal cord.

What is the life expectancy of someone with white matter disease?

It is not possible to stop disease progression, and it is typically

fatal within 6 months to 4 years of symptom onset

. People with the juvenile form of metachromatic leukodystrophy, which develops between the age of 4 and adolescence, may live for many years after diagnosis.

Can white matter lesions in the brain be nothing?

White matter lesions observed on brain MRI are usually characteristic and occur in specific areas including the corpus callosum and pons. “However, in many cases, the

white matter lesions as isolated observations are nonspecific”

and could be due to MS or another cause, explained Drs Lange and Melisaratos.

What is the function of white matter related to memory?

Long thought to be passive tissue, white matter affects learning and brain functions,

modulating the distribution of action potentials, acting as a relay and coordinating communication between different brain regions

. White matter is named for its relatively light appearance resulting from the lipid content of myelin.

Is gray matter good or bad?

While after death the brain does turn a grayish color, hence the name, while you’re alive your gray matter is

a healthy pink

due to all the blood that’s constantly flowing through.

What parts of the brain are grey matter?

Grey matter is distributed

at the surface of the cerebral hemispheres (cerebral cortex) and of the cerebellum (cerebellar cortex), as well as in the depths of the cerebrum (thalamus; hypothalamus; subthalamus, basal ganglia – putamen, globus pallidus, nucleus accumbens; septal nuclei)

, cerebellar (deep cerebellar …

Does everyone have white matter in the brain?

“Gray matter” is only one of two types of brain tissue; the other “white matter” is rarely mentioned. Yet

white matter makes up half the human brain

and has not been thought to be important in cognition or learning outside the context of pathology.

How do you treat white matter in the brain?

White matter disease doesn’t have a cure, but there are treatments that can help manage your symptoms. The primary treatment is

physical therapy

. Physical therapy can help with any balance and walking difficulties you may develop.

What is the difference between white matter and grey matter?

What is the difference between grey and white matter in the brain? … The

grey matter

contains the cell bodies, dendrites and the axon terminals, where all synapses are. The white matter is made up of axons, which connect different parts of grey matter to each other.

What does it mean when you have white matter on a brain MRI?

White matter disease is commonly detected on brain MRI of aging individuals as

white matter hyperintensities (WMH), or ‘leukoaraiosis

.” Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life- …

Does white matter disease cause memory loss?

Brain scientists have found that white matter disease

chips away at memory by shrinking the brain

, and contributing to dementia more than initially thought.

How do you keep white matter healthy?

White matter, on the other hand, responds mainly to a

steady diet of healthy fats

, because brain matter is made up of fats. If you are out for dinner, dump dark green olive oil all over your meal. Or go for other sources of wonderful fats: cold water fish, organic nut butters, coconut and avocados.
