Do brain cells grow back????

Answer 1

You have asked an almost impossible answer. 20 years ago there would have been a resounding NO in answer to this question. But then there was the accepted notion that your brain quits growing new cells very early in life. This is now known to be not true. There is a specific area in your brain (hippocampus) that continually grows new cells based on learning and activity.
There are very many unanswered questions about whether your brain regrows cells. There are current studies that show that the brain is capable of re-circuiting itself following brain injuries. This compensatory process may or may not be the regrowth of new neurons. There is the possibility that existing cells are re-educated to take up new roles for these new circuits. So the best answer to your question to date is, scientists don't know for sure. The COOL thing about this is there enormous amounts of research in this field going on right now. Ask this very same question again in 3-5 years and there will be a definitive answer. But for now just accept the possibility that they might and refuse to accept an absolute no as an answer.

Answer 2

Do Brain Cells Grow Back

Answer 3

No,the neurons in our brain don't unfortunately grow back.They are eventually replaced by the glial cells,wich support them and have the role in nutrition.But the most important cell ,the neurons do not recover.And if too many are lost,the brain develops certain diseases like:Alzheimer's,Parkinson,some also say epilepsy.Because,you see,the body's nervous system isn't represented just buy the brain,also our spine(colona),takes parts from the system.And so,neurons can be found even in the marrow of our spine(bake-bone).

Answer 4

No. There are certain cells that can't multiply. Muscle cells also can't grow back.

Answer 5

i agree with biosciguy. before scientists would say No to this question. but nowadays with modern technology scientists are now discover many new things (this include brain cells) thus now they still using these technologies to do a research on brain cells. thus, your question is hard to answer (for now that is.)

Answer 6

It was previously thought that they didn't, but recent evidence suggests that stem cells in the brain stem do, in fact, replace dead or dying brain cells, to a certain degree.

Answer 7

Generally, neurons do not grow back (although recent literature shows that some growth is possible). Neuroglial cells on the other hand are mitotic.

Answer 8

I think it depends on the type of brain cell-- there are way more than one.

Is there a neuroscientist in da house?

Answer 9

barely.. answer is yes, but you need to be continuously using them.
science has just figured that out - and in general, it's on a small enough scale that it's useless.
so.. dont lose 'em... unless you're a multimillionare - then you can play with weird new junk they're think about.. like implanting/whatnot - use google. i'm not much on typing/explaining junk

Answer 10

Thanks all for answering this questions. I am still unsure of the answer. My grandma is in the hospital with midbrain damage. She is in a coma. I'm just wondering if she can get better? Have anyone went though this problem with any family member? HELP!
