Can Grey Matter Regenerate
How is damage to the CNS different from the damage to the PNS?
Also, why can grey matter not be regenerated, but white matter can?
No: Gray matter cells in the brain do not divide after fetal development. If they are damaged or loss, the body cannot replace them. This is why many strokes are permanent and why injury to the head can be so damaging. ...Read more
Varies: There are many patterns and ages for this to be noticeable. Generally the first thing that becomes a bit of a problem is the remembering of names and faces. Later word search gets more difficult. And there is the classic "where did i leave my (keys, car, wallet, coffee cup, etc.)? This is a slow evolution over many years in the elderly (you are way too young). ...Read more
WM/GM: Both are parts of the central nervous system. White matter is made of glial cells & myelinated axons that transmit nerve signals. Grey matter is made of neurons. The wm coordinates communication between different parts of the brain. The gm is involved in cognition & processing of information, muscle control, sensory perception, memory, emotions, speech. ...Read more
What makes grey matter grey a white matter white? In other words, what is the difference between grey and white matter?
Cells vs. myelin: Gray matter mostly consists of the cell bodies of neurons, while white matter contains myelinated axons. Axons are like connecting wires, and myelin (which is whitish in color) serves as the insulation. For more details see: http://en.Wikipedia.Org/wiki/grey_matter and http://en.Wikipedia.Org/wiki/white_matter. ...Read more
In terms of behavioural addictions, can damaged grey matter linked with hypofrontality cause irreversible damage, if not can it grow back or be repair?
Not clear: The "grey matter" of the brain is the cell bodies of neurons themselves. Physical damage to them is serious and can come from degenerative neurological disorders and traumatic injury. Other conditions such as schizophrenia and internet addiction can also show frontal lobe changes on MRI scan, which may correlate to behavioral changes in executive functioning. It's not known whether these resolve. ...Read more
Porn changes brains: Hi R, One study found smaller gray matter volume and diminished communication between the two halves of the brain in high porn users. Excessive porn users also require more stimulation to get motivated, so the bottom line is, anything in excess is likely to have problems associated with it. Moderation is key. Hope this is helpful. Take good care ...Read more
Not enough info: Not sure what you mean by "white and grey brain matter disorder". Grey matter is basically where brain cell bodies (neurons) are, and white matter is mainly the cables (axons) connecting neurons. Sounds like you had an MRI and need to talk with your doctor about what it shows - "white and grey brain matter disorder" is too vague and doesn't tell me anything useful. ...Read moreSee 1 more doctor answer
White & gray matter: The gray matter in the brain is nerve cell bodies; white matter is the fibers that grow from them. These fibers also have a sheath covering them called "myelin" which is also part of white matter. If white matter is damaged in some way -- by stroke, inflammation, or disease like ms -- it shows up on MRI scans. Gray matter can be damaged also. ...Read more
Blurring: Bluring relates to the brain image on cat scan or mri. It is usually caused by edema (swelling) or damage, causing an accumulation of fluid in the area, so the the gray matter, where nerve cell bodies are located. The white matter contains the nerve fibers that travel throughout the brain. ...Read more
I have been feeling like i can't get a full breath for about a month and i recently coughed up blood and gray matter. What is this?
Due to a recent study, it is said that people who were victims of child abuse as a child have less grey matter in their brains. How do I increase it?
Many ways: Science is now appreciating that there are many ways to enhance brain structure and function. Among the most well documented are mindful meditation, exercise, Yoga, a healthy diet, sufficient sleep, and a sense of gratitude. Learning new things, listening to music, social connectedness, prayer and hypnosis are also good candidates. ...Read moreSee 1 more doctor answer
