During prenatal development, enough "stem cells" differentiate into neurons that each newborn infant has enough multipolar neurons to last a lifetime.  While neurons die continually throughout the life span, barring accident or disease, we still have plenty of neurons left, even into the 2nd century of life.\n\nHowever, certain diseases (e.g., Alzheimer's Disease) cause premature and widespread death of neurons - with devastating results.  \n\nOne of the great hopes we have for stem cell research is that there is very promising data from animal models that "flooding" a neuron-depleted area of the brain with stem cells can repopulate the lost neurons and reform the neural network.

No, this is a myth. A large part of our brain is used as proved by MRI's.

no. as soon as the brain is cut off from the body. the body would not walk.

No, it is an urban myth.\n\nWhile for the people who repeat that myth, it's probably true, the rest of us happily use all of our brains.

You lose brain cells every day without anything happening at all. Various things such as smoking, drinking alcohol or taking drugs, OR being hit in the head hard enough to sustain a concussion, will accelerate brain cell loss. \n\nBut just like with the rest of your body, you also grow new brain cells every day. Therefore, if you get hit in the head and are experiencing some thinking problems-- lack of memory, concentration, etc.-- you will PROBABLY get back most or all of your brain function as long as you don't do anything to aggravate the situation. Thinking problems related to getting hit in the head are more likely caused by pressure from bruising or swelling against the brain, and not actual "loss" of brain cells.

I believe that brain activity is the definition of death. Even if the heart and lungs have shut down, as long as there is brain activity, the doctors don't consider them dead and will work to revive them. However, if there is no brain activity, they won't.

Only if you let it do your thinking for you. The more you let it think for you the smaller your brain cells become.\n\nGet a life cause obviously yours is lacking.

No, we use all of our brains. The "10% use of brains" urban legend is completely false.

Forget about "believe," this is the science forum -- the question should be, is there any scientific proof that these are real?\n\nAnd yes, there is -- there's proof that our brains undergo changes as death approaches (usually from oxygen starvation of the brain), that can produce hallucinations. Neurons fire off in many parts of the brain in an apparent "last gasp" effort to stave off death, probably the brain's way of trying to get the rest of the body to do something to keep it from dying.  That many of the reported experiences are the same, no matter what culture or religion the person is from, suggests that it's something our brains do biologically, and isn't based on learning or life experiences.

The part of the brain called the cerebellum is at the base of the brain and the top of the spinal cord.  This part of the brain governs all the autonomic body functions... breathing, heart beat, many other automatic body functions.  You neighbor may have had a heart beat when he left your presence, but if he was "brain dead" it would not be too much longer when his heart would have stopped beating and his breathing also stopped.  It is the brain that governs your body functions... that is why drugs are such a threat to use... as they attack this part of the brain and eventually kills the person... A normal drug dose amount used one day and again used the next day just may become an OD amount of drug that will damage the brain to the point it will not recover... it will be the killing dose... One never knows...

No - the brain is an organ. However, you can "exercise" it by learning new things and solving problems.  Keeping your brain active helps to stimulate new brain cells and possibly fight dementia in later years.

This is definitely a myth.  We use all of our brain.  The origin of this myth is that only 10% of our brain is made up of actual neurons in the strictest sense.  That means that only 10% of the cells in our brain are the kind that transmit signals and make us think.  The other 90% are called glia.  These cells provide the structural support and nutrients for the neurons, as well as clear away their waste and excess neurotransmitters.  These cells are "used" just as much as the other 10% though.

They do in a developing embryo, but not in a fully developed animal/person.\n\nWhat brain cells CAN do is create connections between each other, creating more neural pathways that aid in recollection.  But if you damage your brain enough, it won't recover.

no. Thank God or we would be brain dead!

No. Blocking a sneeze does not kill brain cells, rather it can give you a stroke. Such a block has a high chance of raising the internal pressure of capillary brain vessels and cause a tear in them. If such thing occurs most of the time you need a surgery requiring opening the skull.

Yes, darling. It is true. Once your brain is gone, it will stop growing and you eventually turn into worm food.
