Which cranial nerve is involved with listening to music and sea sickness?
Vestibulocochlear nerve (CN VIII). More specifically vestibular nerve of CN VIII is responsible for equilibrium and balance.
How does the brain tell from which direction a sound comes answers.com psychology?
The brain picks up the vibrations from the sound waves. It would be like if your phone vibrated on you in your pocket, you could immediatly tell where it was coming from, right?
What role does memory play in your lives?
We have two types of memory. One, is long term. This is the memory when you learn the times tables,or a phone number. The other is short term memory. This is for information that you need for a short time and then not use. At various times in our lives our memory clears itself to make room for new memory. Think of the brain like a computer and our memory is one of the motherboard parts. We need memory for learning, to know who we are, and to know family and friends.
Do smarter people have bigger brains?
No, a bigger brain usually means just a bigger head. We can only access 21.099% of our brain and "that persons brain writes stuff in a bigger font".
Answer #2: Answer #1 is a bit dubious. There is no set percentage of our brain that we use or access. We use what we need, when we need it, and one objective cannot use 100% because that would mean neurons would have to move around. A neuron in your motor cortex cannot process sensory input. We also often utilize the vast majority of our grey matter (The part of the brain that handles the most processes) and most parts of the brain are constanty active. Doing any task often requires most parts of the brain to be active and processing information like sensory input, reasoning, motor control, etc. Even while sleeping, parts of your brain are processing and figures estimate about 15% is the baseline for sleeping. If you were able to use 100% of your brain at any one moment, you would go into a seizure. The myth of a fixed percentage, be it 10%, 21% or whatever is perpetuated as a reason for psychic powers but is completely false.
That said, the answer is debatable and depends on who you ask. Take someone like Einsten for instance. He was a genius with an IQ of at least 150. His brain is normal size for a human brain yet has many more neurons than an average human, he (supposedly) stated that he believes that neurons are the difference, not size. The truth is we don't really know but all evidence points towards no, a large brain does not mean more intelligent and that it comes down to neurons. More neurons = more intelligent.
A reduction in the strength of a signal, the flow of current, flux, or other energy in an electronic system.
What part of the brain controls the brain and brain growth?
the pituitary gland secretes a hormone which controls he growth of all parts of the body
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!
