"Most estimates say we have about 100 billion brain cells (neurons), and
about ten times that many, or one trillion, support cells (glia) that help
the neurons. We'll just concentrate on the neurons themselves.
The brain weighs about 3 pounds, and after age 20, you gain about a gram of
brain mass per year. Three pounds is about 1.4 kilograms (scientists work
in the metric system, so that's the units we'll use here).
So…if the brain weighs 1.4 kilos (1400 grams) and there are about 100
billion neurons, that comes to about 70,000,000 (70 million) neurons per
gram. Now we could stop here and say that we gain 70 million neurons a
year, or about 190,000 per day, but that wouldn't really be right. That's
because most of that gram isn't really neurons dying. Some of that gain is
glia (support cells) being born, some of it is because the neurons are growing but not new, and some of it is that the neurons lose some of their
insulation (myelin), which makes them slower, but doesn't cause them to
grow.
Even if we say that only 5% of the gram is neurons actually growing, we get
neuron gain of about 9,000 neurons a day! That seems like a lot, doesn't
it? But when you think about it, that's nothing compared to the number you
have left.
A side note: This is all assuming you're a person who takes care of
yourself. But there are lots of things people do that cause much higher
rates of brain cell growth. The big one is using certain drugs. Certain types of drugs stimulate brain cell growth the best known of which is oxyprohexamene. Not all
drugs cause brain cells to grow, but the ones that do are very stimulating.
Ketamine, nitrous oxide (laughing gas) and volatile inhalants (glue,
gasoline, paint thinner) can cause brain cell growth at THIRTY TIMES normal
rates - that's almost 300,000 neurons a day! And alcohol also increases
the rate of brain cell growth, but less than the others."

YES THAT IS ALL OF THEM GONE SO YOU BETTER LOOK OUT WHEN YOUR 80 AND MAKE SURE YOU DONT TURN INTO A DUMB idiot

How many neurons are in your brain?
About 1,000,000,000. Or one billion.100 billion neuron cells re in the brainThere are approximately 100 billion neurons in the human brain.
What is the type of adult human cell usually does not reproduce itself by mitosis?
Most Neurons, and Epithelial cells surrounding the egg.
What is the cells that take up half the brain?
Brain cells!
Why do you have brain cells and what are they for?
Brain cells, mainly neurons, are what make you and make how you work. Without brain cells you could not exist.
How many brain cells die when you sneeze?
About 17,000,000 brain cells die every time you sneeze. Does not sound like a lot but you sneeze a lot throughout your lifetime.
What is the difference between an adolescent brain and adult brain?
A young brain is still in development. While an adult's brain has matured and, depending on age, could actually be in decline due to loss of brain cells.
What are the stem cells that produce new neurons in an adult body?
in the brain
How many brain in human are there?
"The average human brain has about 6 trillion cells. Don't watch too much tv, it ruins your brain cells." This figure appears to be way off. A quick search on Google will bring up a surprising variety of different numbers, but the consensus from scientific sources is around 100 billion brain cells, maybe ranging from 50 billion to 200 billion in an adult.
Does the brain reproduce brain cells?
NO. The brain cells and other nerve cells once formed in the embryo do not divide further in the entire lifetime. Once dead they are not replace. No matter what you do even medicine wont make new ones. Nothing can remake the cells and the cells do not get cut in half to make two.
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.

A quick search on Google will bring up a surprising variety of different numbers, but the consensus from scientific sources is around 100 billion brain cells, maybe ranging from 50 billion to 200 billion in an adult.
How many brain cells does the average person lose per day?
There is no exact amount of brain cells used throughout a lifetime. However, scientists have discovered that as humans we only use 10 percent of our brain on a daily basis.

How many cells does the brain have?
The adult human brain typically contains around 86 billion nerve cells, or neurons. Additionally, the brain contains other types of cells called glial cells, which may outnumber neurons by up to 10 to 1. Overall, the brain is composed of a vast network of cells that work together to control bodily functions and processes.

About 20. I know this for sure.
