What happens if you damage your brainstem?
It depends upon the nature of the damage. The brain stem, or Cerebellum as it is known, controls the body's vital automatic functions of breathing, circulation, respiration and temperature control. Damage to the Cerebellum can result in disruption or cessation of one or more of these functions.
If the damage is immediate, and affects the breathing or circulation functions, then the result is likely to be death. If, however, it is a gradual deterioration, then the patient can be helped to maintain their respiration, circulation and other such automatic processes via mechanical aids. However, the quality of life that they may be left with, may not be very great.
the brain sits where your scull is at the top of your head stupid!!:)
Which part of the brain is sometimes called the 'higher brain'?
The cortex of the brain deals with higher thinking but the frontal lobe involves the ability to recognize future consequences resulting from current actions, the choice between good and bad actions
(or better and best), the override and suppression of socially unacceptable responses, and the determination of similarities and differences between things or events. Even little kids can use their cortex but it takes time for the frontal lobes to fully form between 28-30 years of age. That is why teens and younger people in their 20's do dumb things.
hey im not to sure of the answer but i think that it is what we smell is what ever is in the atmousphere because every little thing that has a smeeling side to it is being let out into the air also like cooking every time we cook a smell goes in to the air and that is the smell we smell it wasnt created it is just formed when we do some thing to some thing even when you smell perfume it is not the same every time because if you trie to put it on some one else it would smell different because that persons skin has a different smell to your own..
how that this has helped
cheers

What part of the brain provides the brain with oxygen and food?
The carotid artery provides the brain with the blood that carries the blood and oxygen.
common-carotid-artery-1
Blood provides the brain and all of our other organs with the oxygen and nourishment it needs. Blood is kind of like the body's highway, it gets everything where it needs to go.
When our heart beats blood is sent to the lungs, then when we breath the red blood cells absorb oxygen, then when our heart beats again the blood is sent around out body like to our arms, legs and brain etc etc. This oxygen is then passed to the different lims and organs.
Then the cycle starts again.
Do women like men with out foreskin?
In general, I'd say NO. Especially if you do not take daily showers or wash yourself immediately after sex. In no time, it smells a little fishy, if you get my drift. It can get nasty, fast...!!!
It's a matter of what they're used to. A girl shouldn't tell a guy to get his penis trimmed, any more than he should tell her to get her untidy labia removed.
What happens to sound when it enters the brain?
Once sound enters the ear canal it impacts on the tympanic membrane (The ear drum) its here in the middle ear that sound sound pressure is converted in to mechanical energy. Attached to the tympanic membrane are 3 bones (the smallest in your body), the malleus, the incus and the stapes (or the hammer, anvil and stirrup), these bones are responsible for two things, they are able to regulate the amount of sound coming in to the ear by expanding and contracting the tympanic membrane to protect the ear (although theres around a 100ms delay). They're also responsible for transferring these vibrations to the cochlea in the inner ear through the oval window. Put simply, the cochlea is filled with a watery liquid known as perilymph which moves in relation to the vibrations coming through the oval window. The perilymph then stimulates the thousands of little hair cells (which are 'tuned' to recognise a particular frequency), which convert the energy once again from mechanical to electrochemical impulses before being passed to the auditory nerve and to the brain for further processing.
Sound enters your ear through vibrations, and are usually funnelled into you ear by the pinna which is the flap of skin at the top of your ear- the part that you can see. These vibrations then continue down the ear canal, and the ear drum vibrates (the ear drum is a thin layer of tissue) the vibrations having been made larger by the force of the ear drum vibrating, and the then the sound travels through the ossicles, into the liquid in the snail shell-shaped cochlea, and the-nerve generating hairs combined with the nerve cells of the cochlear nerve send impulses to the brain.
When you first hear a sound, it goes through your outer ear and then through your ear canal. It passes the anvil, stirrup and the hammer (I'm not sure if it goes through) and through the cochlea which goes to the nerves *gasp* which goes to your brain.
At the moment a brain transplant is not possible.
It is not possible at the moment, but I wouldn't be too supprised if it was in the near future. And yes, the donor would have to be dead. But (I'm assuming) the brain on the other hand, would have to be alive, so the donor would have had to just died. Also, take into consideration that a transplant would be extremely hard to do, considering the brain is so delicate.
What is the cost of brain surgery?
Brain surgery is expensive but it depends on a lot of factors such as complications after surgery and how long your hospital stay is. I had brain surgery in November of 2006 but I had complications that left my left side weaker than my right and was required to have extensive therapy and over a month and half hospital stay. Over all, my bills have reached close to $750,000 or more. That is not including prescription costs since my surgery.
Well, it depends on what you mean by sea-smell. If you mean the smell of the sea, then that would be hard to describe. It's a tangy sort of smell, similar to salty water. Just imagine water with salt, rotten seaweed, and the occasional dead animal stink in it.
How might the motor cortex be active while driving a car?
it helps you press the brakes and accelerator.
Your brain is only a part of your functional environment. Thinking is a function of yourself as an experient and a personality. The brain, however complex, is not the experient and is not the personality. It is you the experient and your personality who think using the brain as an instrument of thought. Therefore, your brain does not think.
One, and it's about the size of a walnut. Actually, scientists thought for a while the stegasaurus may have had a brain-like structure in it's tail. The expansion of the spinal column in the pelvis gave rise to the incorrect idea that dinosaurs had two brains. Yes, the size of a walnut!

What is a person who has brain damage called?
It really all depends on what the brain damage was. Someone might have had a stroke, a traumatic brain injury, a tumor, bleeding in the brain, or many different things.
UCLA professor of neurosurgery and physiological science Fernando Gomez-Pinilla, has spent years studying the affects that food, exercise and sleep have on the brain. Considering how we tend to feel after eating too much, sleeping too little or falling out of shape, Gomez-Pinilla's interest in this makes sense. He found that omega-3 fatty acids helped to improve memory, learning and protected against depression, mood disorders and even dementia. While you can find omega-3 in pill form, the scientists state that you will receive more benefits from actual food that contains this valuable nutrient. Some of these foods include flax seed, salmon, walnuts and squash. Omega-3 fatty acids help with the plasticity of your synapses - and considering the damage that is done to these vital parts of the brain by a TBI, this study may be worth paying attention to. We've already discussed how a brain injury often worsens with time and can lead to dementia, but with active preventative measures such as an improved diet and increased exercise, you may be able to help prevent or stall this deterioration. Gomex-Pinilla said that "The brain and the body are deficient in the machinery to make DHA; it has to come through our diet." The DHA is a type of omega-3 fatty acid, and is in foods such as salmon. An interesting addition to this is the suggestion that a lower calorie diet may also help with the brain's overall health. Too many calories can increase cell vulnerability to free radical damage and also decrease the flexibility of your synapses, leading to memory and learning problems. Another especially beneficial supplement is folic acid. It has been proven to help with the effects of antidepressants and to prevent the mental decline that comes with aging. If it helps with aging…perhaps it will benefit a damaged brain? Our lesson from this study seems to be smaller portions with higher nutrient values. Not always the easiest shift to make in our fast food oriented society, but one worth making if you value your mental health!
What part of the limbic system is vital in converting short-term memory to long term memory?
lhypothalamus
What is called when a child has value shunt caused of water in the brain?
The shunt used for a person who has hydrocephalus ("water on the brain") is not called a "value shunt". It is usually called a "ventriculo-peritoneal shunt" or "VP shunt" for short. Sometimes a "ventriculo-atrial shunt" or "VA shunt" is used instead.
What part of the brain functions to filter out unimportant stimuli?
thalamus
reticular activating system
