Can the brain be donated?

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.

What is sea- smell?

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.

Does the brain think?

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.

How many brains do they have?

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.

How can you help your brain?

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 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 body region is controlled by the largest area of the motor cortex?

There is something called the Homunculus that illustrates which parts of the motor cortex control which region. It ends up looking like a C with the leg being the smallest part and the face especially the tongue being the largest.

How does your brain communicate with your body?

I think the answer you're looking for is nerves. Nerves are the types of cells that transmit signals from your body to your brain, and brain to your body. Nerve cells release charged molecules in a controlled way to create electrical signals that can propagate information across the body.

Can a brain get dehydrated?

  1. Signs of dehydration are noticed before brain dehydration signs. If the symptoms of dehydration are noticed before the brain suffers from dehydration, you will not experience detrimental effects on the brain. Common dehydration symptoms include a dry or sticky mouth, little or no urine released, no tears being produced, eyes sunken in their sockets, lethargy and, in severe cases of dehydration, coma. One physical sign of dehydration can indicate that dehydration is beginning to affect the brain: you will exhibit a soft spot on the top of your head, like an infant has. This condition is known as sunken fontanels.
  2. Mental EffectsUntreated
  3. When dehydration affects the brain, mental ability will be affected immensely. Besides the symptom of physical lethargy, you will also have mental fatigue. As the brain dehydration continues, you will begin to have some memory problems and experience confusion.
  4. When left untreated, brain dehydration can have serious effects. Due to the deterioration of brain cells from lack of water, brain dehydration can lead to seizures and permanent brain damage, which can impair your physical and mental abilities.
  5. Found this answer through search Signs and symptoms of brain dehydration.

It depends on the area of the brain affected -- here's a link to a good website that gives you specific problems caused by damage to specific parts of the brain.

If a man has a brain damaged in an accident , he could well be in a coma or even end up as a vegetable.

What part of the nervous system perceives cutaneous sensations such as warmth?

The part of the nervous system that enables us to experience the sensation of hot or cold, pain or pressure is the hypothalamus, located in the brain. The hypothalamus sends messages to the rest of the body. As an example, when you begin to shiver from cold, the hypothalamus sends a message to muscles to begin to work quicker, generating heat.

What is the part of the brain that coordinates your muscles so you can walk?

The cerebellum (infratentorial or back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
