What is GREY matter in the brain?

Grey matter is a type of tissue in your brain and spinal cord (central nervous system) that plays a crucial role in allowing you to function normally from day to day. It consists of high concentrations of neuronal bodies, axon terminals (endings) and dendrites.

What is gray matter in the brain responsible for?

The grey matter has a large number of neurons present, which allows it to process information and release new information through axon signaling found in the white matter. [6] The grey matter throughout the central nervous system allows enables individuals to control movement, memory, and emotions.

What is brain white matter?

White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.

What kills grey matter in the brain?

A common cause of grey matter nerve cell death is a lack of blood flow to the cells. As these cells are constantly working, they require a large supply of oxygen (through your blood) to function efficiently.

What foods increase grey matter?

Research suggests people who regularly eat fish tend to have more gray matter in their brains—and gray matter contains most of the nerve cells that control decision-making, memory and emotion. If it's fatty fish like salmon, trout, albacore tuna, herring and sardines, even better.

How to repair white matter in the brain?

There are currently no adequate treatments for white-matter injury, which often follows central nervous system maladies and their accompanying neurodegenerative processes. Indeed, the white matter is compromised by the deterioration of the blood–brain barrier and the demyelination of neuronal axons.

What are the four stages of white matter disease?

Four stages were defined by dividing individuals into simple quartiles corresponding to those with the lowest total WMSA (Quartile I, n = 25), mid-low total WMSA (Quartile II, n = 25), mid-high total WMSA (Quartile III, n = 25), and highest total WMSA (Quartile IV, n = 22) (Fig.

What damages gray matter?

Neuronal death is at the heart of grey matter brain damage.

Grey matter is therefore very susceptible to injury when oxygen levels are low (hypoxia) such as during an ischemic event. Damage also occurs when the local environment changes such as during an intracerebral hemorrhage or when physical damage occurs.

What increases grey matter in the brain?

The human brain has been shown to exhibit changes in the volume and density of gray matter as a result of training over periods of several weeks or longer. We show that these changes can be induced much faster by using a training method that is claimed to simulate the rapid learning of word meanings by children.
