Question 1

can grey matter regenerate?

Accepted Answer

No: Neural cells after fetal development do not divide and therefore regeneration is not possible.  There is a molecular switch involved and scientists are working on ways to turn it off.

Question 2

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?

Accepted Answer

Regenerative capacity: Peripheral nerves can regenerate to some extent. Central nervous system, both grey and white matter have very limited regenerative capacity.

Question 3

can gray matter grow back?

Accepted Answer

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.

Question 4

what happens when you start loosing gray matter?

Accepted Answer

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).

Question 5

what can too much grey matter mean?

Accepted Answer

Grey Matter: Grey matter contains many of the cells of the brain/ central nervous system. Here is an article  about large volume of grey matter and distractibility. (http://www.newscientist.com/article/dn20453-easily-distracted-people-may-have-too-much-brain.html)

Question 6

what is grey matter heterotopia?

Accepted Answer

Neurologic Disorder: Gray matter heterotopia is a neurologic condition that is often associated with seizures in which bits of gray matter are scattered  in areas of the brain they shouldn’t be (sometimes just one area).

Question 7

does the spinal cord have gray matter?

Accepted Answer

Spinal gray matter: Yes, it does.

Question 8

is gray matter disease the same as dementia?

Accepted Answer

Not exactly: Various types of dementia affects grey mater or white mater or both. Depending on type of disease, reversibility, extent location may affect the intellect (dementia).

Question 9

what problems can occur with being born with less gray matter in my body than normal humans. what problems can arise from this?

Accepted Answer

: Two types of tissue in the brain and spinal cord can be distinguished with the naked eye. Grey (gray) matter with a higher density of nerve cell bodies processes, and white matter with mostly nerve fibers transmits information. This applies to the nervous system, not the rest of your body. Associations between some traits and reduced grey matter are being studied but our understanding is limited

Question 10

what is grey matter of the spinal cord composed of?

Accepted Answer

Grey Matter: Grey matter of the central nervous system contain nerve cell bodies. If you need more specific information, please rephrase your question.
