The human brain is the main organ of the human nervous system. It is located in the head, protected by the skull. It has the same general structure as the brains of other mammals, but with a more developed cerebral cortex. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using a measure of relative brain size, which compensates for body size, the quotient for the human brain is almost twice as large as that of a bottlenose dolphin, and three times as large as that of a chimpanzee. Much of the size of the human brain comes from the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The area of the cerebral cortex devoted to vision, the visual cortex, is also greatly enlarged in humans compared to other animals.

The human cerebral cortex is a thick layer of neural tissue that covers most of the brain. This layer is folded in a way that increases the amount of surface that can fit into the volume available. The pattern of folds is similar across individuals, although there are many small variations. The cortex is divided into four lobes – the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. (Some classification systems also include a limbic lobe and treat the insular cortex as a lobe.) Within each lobe are numerous cortical areas, each associated with a particular function, including vision, motor control, and language. The left and right sides of the cortex are broadly similar in shape, and most cortical areas are replicated on both sides. Some areas, though, show strong lateralization, particularly areas that are involved in language. In most people, the left hemisphere is dominant for language, with the right hemisphere playing only a minor role. There are other functions, such as visual-spatial ability, for which the right hemisphere is usually dominant.

Despite being protected by the thick bones of the skull, suspended in cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier, the human brain is susceptible to damage and disease. The most common forms of physical damage are closed head injuries such as a blow to the head, a stroke, or poisoning by a variety of chemicals which can act as neurotoxins, such as ethanol alcohol. Infection of the brain, though serious, is rare because of the biological barriers which protect it. The human brain is also susceptible to degenerative disorders, such as Parkinson's disease, and Alzheimer's disease, (mostly as the result of aging) and multiple sclerosis. A number of psychiatric conditions, such as schizophrenia and depression, are thought to be associated with brain dysfunctions, although the nature of these is not well understood. The brain can also be the site of brain tumors and these can be benign or malignant.

Funny this documentary is on the functioning of the brain and yet there is no closed captioning.

@ 6:00 That is NOT why the military does that, that's just what they say as propaganda.  That is training for the person holding the gun ;)

Great program until we get to the pseudoscience at the end. Then we're reminded that History Channel is a basket of pseudo-intellectuals.

If we put everything we learned in this video together, the brain can only come up with one conclusion: Tiger Woods is a psychopath. O_o

Does Clive still have the ability to learn and retain new sheet music though or just play music he already knew before the brain infection?

I am being held hostage via the high-tech system LRAD and Satellite communication by a G2/G8 project. Programs used on my organism are permanent sleep deprivation, brain drain, traumatising mind control, projections and 24/7 Satellite communication. The 24 hours talking into my neurological system "operators" identified themselves as sub-contractors of the companies Juelich, Fraunhofer First, Frahns Australia and as data-collecting sub-contractors of so called SP levels on cloud network intranet. They state to be part of a G2/G8 neuromorphic data collecting conglomeration between Australia and Germany involving the BNCI Horizon 2020. All Satcom abusing "human aid" are and speak German. Some claim to broadcast/operate from the location of St Lucia Queensland. They say they know the campus and surroundings of the brain centre in Brisbane very well, say they work from institutional work places, in "interest groups", that are partly competing against each other. Training, familiarisation with equipment and computer screens, competition amongst each other and crude pirating of bio-data, as well as "searching and finding the interfaced organism via BioAPI and satellite" are all part of the groups interest. I am being tormented and tortured remotely via the use of military-grade equipment and state-of-the-art special screening software and equipment. Data is being passed on to the "conglomerates| and "partners" of the German "brain project". I am being passed around between "interest groups" pirating my bio-data. They're all abusing Satellite communication and psychotronic energies on my organism. Pure torture. I am being told to be a "subject to human experimentation" within a decimation program leading to total exhaustion, sickness and death of the organism. They admit via Satcom, that they have shot down my car electronically using a Satellite driven ION beam to immobilise me for easier tracking and data backflow . They have, which they say is part of the "traditional mind control programs" broken into my former apartment. An apartment of which I have been "burned out of" via abuse of psychotronic energies. I am being deprived of all human rights by the above groups. Their criminal activities add up to a 10 year jail term. I'm asking you stop these illegally operating organisations from taking me 24/7 prisoner on LRAD and SATcom. Thank you very much, please help to free me from their SP-level cloud intra networks !

In fact the muscular memory is greater than de psicological memory, is easy to repeat a ATM PIN than to speak it, there is some kind of mechanics memory that peaple in coma could else experiment
