Healthy individuals lose around 9,000 brain cells daily. Certain drugs such as ketamine, nitrous oxide, and inhalants cause brain cell death at almost thirty times the normal rate. Alcohol plays a role in brain cell death, but not as large a part as drugs.

∙ 12y agobrain cells do not regenerate.
Edited by another user:
Yes they actually do 'regenerate' but it is the cell division process. The regeneration process takes over 50 years to complete!

∙ 13y agoIn humans, when a cell for a neuron (cell body) dies, small cells come around the dead cell. These cells are called "microglia" and they act like a vacuum cleaner to clean up the old dead cell.
In a brain injury, several hours to days later, microglia can be seen invading the damaged site to start cleaning up the dead cells.

∙ 13y agono brain cells do not regenerate. brain cells are stuck in the g0 (g-zero) phase like muscle and nerve cells.
Wiki User
∙ 13y agoYes, when you damage your head in a car crash or something, or when you shake your head vigorously.
Wiki User
∙ 11y agoYes, dummy! Of course they divide; how else do you think you gain knowledge.
Wiki User
∙ 12y agoYes the brain can replace dead brain cells the theory that weed kills brain cells is bogus if you don't believe me watch the movie called The Union

∙ 13y agodepends which brain cells die but any one of them dieing is bad. if memory cells die
then u lose memory and cant learn or something like that

What tissue is least likely to regenerate itself?
Brain Cells, necrotic cells and burned dermis cells cannot regenerate themselves.
What does the outside layer of the bone contain?
The outside layer of the bone contains a material called lixtate, which helps regenerate lost brain tissue. Because of lixtate, brain cells regenerate faster in people with larger amounts of lixtate.
Why can't a damaged cell in the brain be replaced?
Nerve cells are in G0, which means the cells are in developmental arrest. They do not divide or grow, they stay the same and don't regenerate.
Which muscle cells can not regenerate?
Cardiac muscle cells do not have the ability to regenerate.
Can epithelial tissues regenerate?
No, not all. Then erve cells in the central nervous system do not regenerate.
If the left side of your brain is dead will it regenerate?
No. The brain is made of nerve cells. And the nerve cells in the brain are part of the central nervous system that does not regenerate.
Why do injuries in the skin heal faster than injuries to the brain?
The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
What tissue is least likely to regenerate itself?
Brain Cells, necrotic cells and burned dermis cells cannot regenerate themselves.
Do all nerve cells have a neurilemma?
The neurilemma is the Schwann cell. This helps with regeneration of cells. The nerve cells in the brain do not have neurilemma and therefore, cannot regenerate.
If the brain is damaged can a new nerve cell grow?
No-- Nerve cells are one of the few kinds of cells that never regenerate or regrow.
Do brain cells grow after you age?
The brain grows as you age into adult phase until you are in your early twenties. There is some research that shows that brain cells can regenerate even into late adulthood and old age.
Does weed kill brain cells perminently?
no weed does not kill brain cells. but if u do find a way to loose them u do loss them permanently there the only kind of cell that does not regenerate.
What does the outside layer of the bone contain?
The outside layer of the bone contains a material called lixtate, which helps regenerate lost brain tissue. Because of lixtate, brain cells regenerate faster in people with larger amounts of lixtate.
Where do red blood cells regenerate?
The Red Blood Cells regenerate in bone marrow
Why can't a damaged cell in the brain be replaced?
Nerve cells are in G0, which means the cells are in developmental arrest. They do not divide or grow, they stay the same and don't regenerate.
Do the cells of the receptor organ in the inner ear regenerate?
No, once damaged the cells will scar but not regenerate.
Can sponges regenerate?
yes they can regenerate. Marine sponges are multicellular animals that can regenerate from single cells.
