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

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

The central nervous system of the brain is made up of two kinds of tissue: grey matter and white matter. 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 do the grey and white matter in the brain represent?

The grey matter represents the high concentration of cell bodies of the neuron. The inner region of cerebrum is composed of white matter which is also called cerebral medulla. The white matter represents the high concentration of axons which gives it lighter appearance.

What happens when grey matter decreases?

Aside from a loss in cognitive functioning, grey matter decline can lead to motor function issues such as losing control of fine motor skills. The decrease in motor function could contribute to the uncontrollable shaking that is a symptom of Parkinson’s Disease.

What can damage grey matter?

As grey matter covers many areas of the central nervous system and is the outermost layer to the brain specifically, this makes it susceptible to being damaged. One of the most prevalent medical problems involving grey matter occurs when there is a plaque build up in one or more areas of the grey matter in the brain.

Can you rebuild gray matter?

Along with the health benefits associated with physical exercise, working out is scientifically proven to increase the amount of grey matter in the brain. According to a study found in the Journal of Gerontology, ‘aerobic exercise training increases brain volume in aging humans’.

What is the purpose of white matter in the brain?

In the most general sense, the gray matter of the brain facilitates information processing, and the white matter facilitates information transfer; both are critical for efficient operation of the neural networks responsible for a specific mental domain.

What does a lot of white matter in the brain mean?

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- …

Can white matter in the brain be repaired?

White matter injuries are very serious, but, depending on the type and extent of the injury, extensive recovery may occur. As long as the neuron cell bodies remain healthy, axons can regrow and slowly repair themselves.

Can grey matter be restored?

Some newer research suggests that some areas of the brain can make new neurons, called neurogenesis, but this is still an unproven theory. For now, there is no known way for you to replace lost grey matter.

Can brain grow back grey matter?

As long as the neuron cell bodies remain healthy, axons can regrow and slowly repair themselves. Functional recovery may also occur if the information can be transmitted through an alternative route. In many cases, this occurs through the strengthening of weak connections that already exist.
