How often do brain cells regrow?

Answer 1

Brain cells are the only, if not one of the few, cells that are supposed to stay in your body for your entire life so they do not get replaced.

Actually, research over the last few years has shown that the human brain can grow new brain cells. Particularly the ones used in cognitive memory and learning capability.

Answer 2

No. The amount you are born with is the highest amount you have for the rest of your life. It is the only cell in the body that does not regenerate. See the related link for more information. This answer is now out of date - new research shows that at least in the hippocampus of the brain, there is the potential for new cell growth. See http://www.brainlightning.com/regen.html for further details of the research.

Answer 3

an old debate and myths is that they do not regenerate. But an alchoholic drinking everyday killing the brain cells would run out in some 20 years or so if the cells did not regenerate.
actually I believe scientist allready admited as to that braincells do regenerate.

Edit: At least some parts of the brain (i.e. the hippocampus and at least three parts of the cerebral cortex) have been shown to regenerate brain cells [1, 2], which would seem to be good news for the control of emotions, memory, decision making, visual recognition, and 3D representation. I'm not an expert in this area, so there's probably a lot more relevant information I didn't find.

Answer 4

Brain cells do not typically regenerate or regrow like other cells in the body. However, neurogenesis, the process of creating new neurons, can occur in certain parts of the brain, such as the hippocampus, throughout life. It is important to maintain brain health through activities like exercise, learning new things, and getting enough sleep to support brain function.

Answer 5

yes
