Can a human brain think more or can a frog's brain?
A frogs brain is different than a humans beacuse they think about different things than humans do and they have a smaller brain with alot more blood cells, but humans have lots of blood cells too.
Can epilepsy cause brain damage?
The question here was "CAN epilepsy cause brain damage?" The answer is an unequivocal, "YES, it can" Frequent and/or prolonged seizures can indeed cause brain damage. However, most people that have Epilepsy are properly diagnosed, treated and monitored, so medication can assist them to live normal lives and reduce this risk. Often someone who has Epilepsy has it as a result of damage to the brain, like a traumatic head injury in something like a car accident. Unfortunately, undiagnosed or untreated epilepsy -- or poor compliance with medications and treatments --- can trigger a seizure which could cause a car accident. For that reason, anyone who has had a seizure must surrender their driver's licence until it no longer presents as a hazard. There are specific guidelines available from the State or Provincial Departments of Transport in your area.
Is the midbrain part of the brainstem?
Yes, it is where the spine enters the brain and includes the medulla oblongata, the pons and the tegmentum. Parts of the basal ganglia are also present in the brain stem. Respiration and heart function is controlled by the medulla. The pons is the relay of motor system impulses from the body and brain through the cerebellum. The basal ganglia is involved in motor function initiation and the inhibition of unnecessary motor impulses.
Is the brain constantly active whether a person is asleep or awake.?
True. Brain wave activity changes from the waking state through the various stages of sleep, but the brain is active all of the time. When the brain is no longer active at all, death is at hand.
What is involutional changes of the brain?
Evolutionary changes in the brain happens with age. It is a normal process that occurs starting around the fourth decade and progressively happens. Although all life spans are not the same so the predictable evolutionary changes vary.
What causes inflammation of the brain?
One is west nile virus, caused by mosquitoes.
There are more than a dozen viruses that can cause encephalitis, spread by either human-to human contact or by animal bites. Encephalitis may occur with several common viral infections of childhood. Viruses and viral diseases that may cause encephalitis include:
- mumps
- Epstein-Barr virus (EBV)
- cytomegalovirus infection
- HIV
- herpes simplex
- herpes zoster
- herpes B
- polio
- mosquito-borne viruses (arboviruses)
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.
