Losing brain cells! Do brain cells grow back again like hair?!
Answers: the fact is once you lose a brain cell, that's it. it does not grow back like a skin cell, or a hair. one beer, a glass of wine or a 1oz. shot of whiskey kills 1,000,000 brain cells. a night of heavy drinking..... untold amounts. brain cells die every day on their own, whether you're a drinker or not..... to date, no scientist knows roughly how many cells the brain contains, which is why it is so fascinating. i don't mean to bore you with details, but the kicker is people who do stuff to kill brain cells become the greatest thinkers of our time....freud, ben franklin, poe, and lest we forget, one of the greatest guitarists ever, keith richards. i mean that guy's brain dead, and still pumps the rock out! sorry, just an opinion. but you understand my point...
No they do not.
No, brain cells do not grow back!! Once they're gone.. say bye bye
no sadly the dont
No, though I don't know why not.
nope, alcohol is a good way to loose them faster
from the age of 19yrs, we start to lose brain cells - huge numbers every day?
I don't believe that they do. Fortunately, you seem to have more than average!
Scientific studies say we lose them as we grow older and they never grow back. I beg to disagree, though. Einstein was still at his best in his old age before his death. And I'm 95 years old. :=p
No, brain cells do not replicate or grow back. They are the ONLY cells of the body along with some nerve cells that to not rejuvenate.
no, once they are dead, they are dead.
No, they do not come back, but you do not lose them every day. scientist believe that humans have about 100 billion nerve cells (and ten to fifty times more of supporting
cells in the brain with them!). scientist are unsure of whether there is significant change in that number over later life. There is a shrinking of brain mass in old age. But cell numbers stay about the same, as far as is known. When brains change in function, it is not usually due to losing or gaining cells. It is usually due to changes in connections
between cells. These are called synapses. Each brain cell in a human brain receives input from 1000s of other cells, and each of these 1000 cells can put 100s of synapses on that 1 cell that it is communicating with. Each cell therefore can have tens of thousands of synapses. It is the weakening and strengthening of these synapses throughout the brain, that changes how the brain functions for the most part. That is one of the working theory. But the brain is the most complicated object yet encountered (more cells in it that stars in the galaxy!).
I think saying all that, my head it going to explode!!

The brain has what is know as "brain plasticity" meaning if one part of the brain is damaged, another area in the brains compensates.
