Gray And White Matter Of The Brain
White matter is one of the two components of the central nervous system and consists of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because myelin is composed largely of lipid ...Read more
Many causes: White matter lesions can be caused by a very wide range of things, ranging from toxic exposure to multiple sclerosis to hypertension to chronic migraines. A neurologist can help you put the imaging findings into perspective with the rest of your clinical picture, and guide further workup and treatment as needed. ...Read more
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
Description: The central nervous system has white matter which transmits signals from one area of the brain to another (cerebrum and lower brain centers).Involved in how the brain learns. The gray matter is in areas of the brain that involve muscle control, sensory perception such as hearing, speech, vision, emotions and memory. ...Read more
Brain white matter: "white matter" refers to the nerve fibers that facilitate communication between nerve cells -- along with myelin, a fatty sheath that covers the them. White matter is below the surface layer of the brain, and can be followed all the way down the spinal cord. Strokes can injure these areas; some people have cognitive changes as well as physical symptoms afterwards. ...Read more
Life and effort: There is no actual need for costly and elaborate programs to improve brain capacity (presuming non-disease state). Pay attention to what is around you. Think about it. Analyze it. Dig through the endless resources of the internet. Challenge yourself with new ideas and examine your beliefs. Have intelligent conversations. Intentionally vary your activity. Get physical exercise. Live fully! ...Read more
Communication: "white matter" refers to the nerve fibers that allow communication between nerve cells -- along with myelin, a fatty sheath that covers the them. Nerve cell bodies are "gray matter." white matter is below the brain's surface layer, and can be followed all the way down the spinal cord. Strokes can injure these areas; some people have cognitive changes as well as physical symptoms afterwards. ...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
What does it mean when the Grey matter in the brain is leaking into the white matter of the brain? And what kind of effects can it have?
Which planet we on?: Here on Earth there are no human beings who leak Grey matter into white matter. Do you have a report of some sort that you're looking at & trying to interpret? The only thing I can think of that would have any remote significance to what you're saying is called "heterotopia" which refers to islands of gray matter within white matter territory. Seizures are known to occur as a main manifestation. ...Read more
I'll Try: You know that Hannibal movie where the guy's head was open you see brain hat you see is the grey matter. If you cut deep into a person's brain it looks more white, hence, the white matter. The fancy explanation, grey matter are the cell bodies and white matter are the axons (nerve wires). Your brain is arranged in a way where it just so happens to appear the way you see. ?W ...Read more
Could cryofibrinogenemia cause multiple t2 hyperintensities in the periventricular and deep white matter of the brain?
Mixed cryoglobulin: Most of the literature regarding cryoglobulinemia and neurologic complications is in reference to peripheral neuropathies and not central nervous system dysfunction. Hence, another cause should be sought for the mr abnormalities. Good luck and well wishes. ...Read moreSee 1 more doctor answer
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
Nonspecific: The white cells indicate local inflammation, perhaps the lingering signs of a central nervous system infection. However, this can be present in other conditions, such as arteritis, sarcoid, multiple sclerosis, carcinomatous meningitis, etc. Perhaps would be explained by your doctor as to why spinal tap was done. ...Read more
Almost correct: The gray matter (nervous system tissue with cell bodies) is inside the cord, surrounded by white matter (axons: nerve fibers going to & from the brain). While there is gray matter on the surface of the brain, it is also present in collections deep inside the brain. The organization of the central nervous system is quite complex. ...Read more
