what does frontal lobe do?

It's key in our inhibitions and judgement.

This is a myth that humans only use '10%' of their brain.\n\nAt any given moment in time, subportions of the brain are activated.  But, over time, all parts of the human brain are activated.  Which parts are activated at any given moment have to do with the functions of those parts of the brain and what associations have been established there.  The brain just isn't wired to have all neurons firing at once.\n\nThe evidence of what parts of the brain fire and when is being accumulated by having people perform specific tasks while having their heads scanned by CAT and PET scanners.  These are creating maps of the activity.

I would alter the architecture of the human skull as the brain is not very protected in incidents that involve head trauma. For instance, the ethmoid bone is very sharp and any blunt force to the anterior portion of the head, may cause the frontal lobe to dig into this area and cause permenant damage. This damage woud be to the limbic system and personality.

imagine what it's doing to your brain.....

The brain is an extremely complex part of the human body; therefore, there are dozens of places a person can use to make a choice. However, my guess would be all of the brain. The cerebral cortex is used for the storage of memory. So if you remember something unpleasant about a choice, you would choose something else. Also, your occipital lobe, auditory lobe, and all the other lobes from each of the senses could help a person make a decision. Like, if you smell bad eggs, then you would not buy those eggs. Also, the cerebellum controls movement, so that could also affect a decision. \n\nEtc. Etc. Etc... :)

minute expansion and contraction of the brain tissue during a cardiac cycle cause CSF movement. I.e when your heart beats, your brain beats also since the brain receives about 25-30% of the total output of the heart. This squeezes the sinuses in the brain.

That 10% story has fallen to Urban Myth status.  New medical imaging techniques can now show which parts of the brain are in use during particular functions, such as speaking, reading, listening to music, etc.  Turns out that your brain uses many differnt parts to do most functions, but certiain functions TEND to concentrate in particular areas.\n\nWhat remains of the myth, though, may actually help understand what I said in the last paragraph.  Many people who have hade severe brain damage and loss of many functions, can sometimes regain at least some ot those functions when the brain learns to use other, undamaged parts to do what the damaged parts used to.\n\nYeah, a vital organ.  An artificial heart can keep a person going, but with no brain, even a beating heart runs in an empty shell.

Function\nThe superior temporal gyrus includes an area (within the Sylvian fissure) where auditory signals from the cochlea (relayed via several subcortical nuclei) first reach the cerebral cortex. This part of the cortex (primary auditory cortex) is involved in hearing. Adjacent areas in the superior, posterior and lateral parts of the temporal lobes are involved in high-level auditory processing. In humans this includes speech, for which the left temporal lobe in particular seems to be specialized. Wernicke's area which spans the region between temporal and parietal lobes plays a key role (in tandem with Broca's area, which is in the frontal lobe). The functions of the left temporal lobe are not limited to low-level perception but extend to comprehension, naming, verbal memory and other language functions.\n\nThe underside (ventral) part of the temporal cortices appear to be involved in high-level visual processing of complex stimuli such as faces (fusiform gyrus) and scenes (parahippocampal gyrus). Anterior parts of this ventral stream for visual processing are involved in object perception and recognition.\n\nThe medial temporal lobes (near the sagittal plane that divides left and right cerebral hemispheres) are thought to be involved in episodic/declarative memory. Deep inside the medial temporal lobes, the hippocampi seem to be particularly important for memory function, and they also seem to play a part in controlling spatial behavior

One of the differences is in how much pre-frontal lobe cortex we have. The pre-frontal lobes have to do with "connecting the dots"...logical analysis, association...it allows us to visualize the future, make rationale judgments and plan. For this reason hey call it the "executive" part of the brain. In humans, 33% of the cortex, the thinking part of the brain, is frontal. In chimpanzees, it's only about 10%. That's a huge difference, signifying that humans have a whole lot more of the kind of brain function that produces higher level intelligence.

I loved this question. Since, since I learned about dreams I always want to say this to any one curious - and there you are.\n\nThe brain has different areas that specialize into different thinkings/functions.\n\nMost areas remain unknown but then a lot are know to us.\n\nThere are special areas for vision, hearing, memory, analysis, judgement, speech, hunger, movements, sensations and so on.\n\nIn the stage of sleep the brain actually is working unlike we normally think! Sleep is actually for the body and some parts of the brain.\n\nThe areas of the brain that operate the heart, lungs, and certain higher analysis are actually working at their best.\n\nThe vision, hearing, sensations and movements are all shut down except for a huge stimuli like clock alarm or excessive light or someone touching us to wake us up!\n\n\nRarely, the vision / hearing may not shut down combined with memory being awake - will lead to a dream that we remember the next day.\n\nThe vision/hearing being awake combined with active conciousness will lead to dreams that we feel at night! (or see at night).\n\nThis is the very reason why some people speak in their sleep or make movement including sleep walking!\n\n\nThe brain mostly analyses all the events that occured during the day from a shorter (day) and longer(years) perspective - so dreams are often vivid.

Great question but a hard one! Humans differ from animals by having a large brain, yes, but there are other parts that are alonst unknown. One of them is located under the brain and is the center of memory and emotions*. Sensations are rather treated by the bulb ending the spinal chord. \n*I forgot the englisn name.\naddition:\nAnimals kills to feed themselves and survive. This also helps the sustaining of Evolution.... Cows eat herbs, nobody says that cows kill herbs but all plants are part of living kingdom.\n\nWe kill because we have incorrect emotional reactions to situations, because we are influence by publicity, news, movies, books,ect. We take bad solutions because we feel unable to react without the use of violence. THIS IS WHAT PARENTS SHOULD TEACH! But they often behave stupidly. Sorry that's a fact and children are emotional hostages of their parents.\nWe are hostage of marketing. And we all forgot a very ugly word: Responsability!!!   we are responsible of protecting our rights! \nI would highly suggest to read the american constitution. This is what America brought to the world. Read it! \nend of addition.\n\nDuring the years 1970, neurologist tried experiment to cure some deseases and noticed that the brain was divided in two segments but these were attached by sort of nerves so that the left hemisphere took benefit of the work of the right hemisphere. So it is wrong that the left hemisohere was logical and ''Manlish" and the right "hemisphere treated language matters. In fact, if we see a cat, this is first treated by the vision center that is a complex part located at the back of the left hemisphere. But recognizing a cat needs the action of the right hemisphere. Since these two hemispheres form our brain, as they are linked by sort of nerves, we don't make the difference. \n\nEmotions and memory are treated in a different organ. This organ can be injured, under-performing ect. \n\nWhat we can explain is that sensations can cause emotional reactions. But neurologists discovered that all the brain was involved in each element whatever it is logical, sensation, emotions, ect. \n\nThis can cause confusions! For example, we tend to Consider love as a better "trigger" to have a child then the need to insure reproduction. This is supposed to insure a better life to the child. All animals take care of their new born childs without educating them for a long period of time. Others give a real formation to their childs (mostly carnivors).\n\nOur animal part is not important. We are among animals who live in society which means that individuals need to communicate with others and have a job that improves the status of comminity.\n\nBut so many things traumatize childs and teens (as well as adults!) that the emtional answer is not always appropriate). \n\nThis was in depht studied by Neurolinguistic Programation or N.L.P. created by Bandler and Grinder.\n\nVery shortly, they say that if you are feeling jealous, whatever the reason is, it is better to switch this emotion to another one that can help you get out of this sad situation. \n\nbut first, there are axioms:\n1- We cannot not communicate (someone who refuses to speak gives a pretty good answer about what he feels! \n2- The one who communicates is responsible of the clearness of the message. \nect. \nBooks are found in libraries and are not meant to cure psychological problems only but to improve our capability to be understood.

The answer to your second question is that the surface of the brain is folded and ridged. This increases the surface area compared to if it were smooth. Only the surface of the brain is used for thinking so having a larger surface means you can do more thinking.

The cerebellum is at the back of the brain, below the cerebrum. It's a lot smaller than the cerebrum at only 1/8 of its size. But it's a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together). Because of your cerebellum, you can stand upright, keep your balance, and move around.

MRI, magnetic resonance imaging, has been used quite extensively recently to explore the function of the brain.

Look in the encylopedia and look up the word brain and information pertaining to (frontal Lobes of the brain) it pertains much to what you are wanting to know. It talks about the thinking and language and control motor thrpugh the body.I found this information in a nursing handbook that I have.It was too much to type so I just gave you a briefing.

it was thought that scrambling the frontal lobe of the brain would be the perfect treatment for people who where manic/depressive/combative and a number of other mental conditions. what it did was make emotionally void zombies of the ones who didn't die from massive infection, toxemia of the brain or just lack of humor! i don't think I'd find anything funny about an icepick shoved in my the corner of my eye while they did the cha-cha to my gray matter! the medical community as a whole abandoned this therapy due to some doctors using it as a why to rid society of the feeble and unproductive and that other things like shock treatments and over medicating would be better.
