Great Question!Here is some information about how the brain works:\n\nHow does your brain work?\n\nYour brain is the hub of your nervous system. It is made up of 100 billion nerve cells - about the same as the number of trees in the Amazon rainforest. Each cell is connected to around 10,000 others. So the total number of connections in your brain is the same as the number of leaves in the rainforest - about 1000 trillion.\nYour brain is made up of 100 billion nerve cells - about the same as the number of trees in the Amazon rainforest.\n\nHow does your nervous system work?\n\nThe nervous system is a network of cells called neurones which transmit information in the form of electrical signals. Your brain has around 100 billion neurones, and each communicates with thousands of others - as many connections as in the world's telephone system, the biggest machine on the planet. Neurones communicate with each other at special junctions where chemicals help to bridge the gap between one neurone and the next. \nThe nervous system is a vast network of interconnecting neurones.\n\nMore about nervous connuections:\n\nThe electrical signals (nerve impulses) carried by neurones are passed on to other neurones at junctions called synapses. The signal may be directly transferred at electrical synapses or, if there is no physical link between adjacent neurones, the signal is carried across the gap by chemicals called neurotransmitters. By using neurotransmitters, the nervous system can alter the way a message is passed on. Each neurone communicates with many others and this contributes to the amazing complexity of the brain.Each neurone communicates with many others.\n\nHope it helps.

The brain contains stem cells which can generate new brain cells to replace old ones. \n\nA single brain cell has little function, the function comes from interaction with neighbouring cells. Loss of "hardwired" brain function can be replaced given sufficient growth and training.

a brain has a processing capacity of 100 trillion instructions per second...the number of internal thought pathways that your brain is capable of producing is:\n\none followed by 10.5 million kilometers of standard typewritten zero's!\n\nCurrent estimates of brain capacity range from 1 to 1000 terabytes!\n  \n"Robert Birge (Syracuse University) who studies the storage of data in\nproteins, estimated in 1996 that the memory capacity of the brain was\nbetween one and ten terabytes, with a most likely value of 3\nterabytes. Such estimates are generally based on counting neurons and\nassuming each neuron holds 1 bit. Bear in mind that the brain has\nbetter algorithms for compressing certain types of information than\ncomputers do."\nhttp://www.sizes.com/people/brain.htm

The amount of surface area of the brain-cerebral cortex allocated to the index finger is GREAT in humans.  Go look up the Homonculus (little man) and see the diagram of the brain with the relative amounts of surface area of the pre central and post central gyri utilized for that finger.  AMAZING.  Esp the idea of fine motor for needlepoint and or for reading braille.

Here's the lot for you, more than what you asked for-\n\nAmygdala – limbic structure involved in many brain functions, including emotion, learning and memory. It is part of a system that processes "reflexive" emotions like fear and anxiety.\n\nCerebellum – governs movement.\n\nCingulate gyrus – plays a role in processing conscious emotional experience.\n\nFornix – an arch-like structure that connects the hippocampus to other parts of the limbic system.\n\nFrontal lobe – helps control skilled muscle movements, mood, planning for the future, setting goals and judging priorities.\n\nHippocampus – plays a significant role in the formation of long-term memories. \n\nMedulla oblongata – contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing.\n\nLimbic system – a group of interconnected structures that mediate emotions, learning and memory.\n\nOccipital lobe – helps process visual information.\n\nParahippocampal gyrus – an important connecting pathway of the limbic system.\n\nParietal lobe – receives and processes information about temperature, taste, touch, and movement coming from the rest of the body. Reading and arithmetic are also processed in this region.\n\nPons – contains centers for the control of vital processes, including respiration and cardiovascular functions. It also is involved in the coordination of eye movements and balance.\n\nTemporal lobe – processes hearing, memory and language functions. \n\nThalamus – a major relay station between the senses and the cortex (the outer layer of the brain consisting of the parietal, occipital, frontal and temporal lobes).

The brain is the organ responsible for thought and other functions.  The mind is the abstract concept that is the culmination of all thoughts, not a physical object.

Handwriting is not controlled by just one part of the brain. It involves many parts. Language, muscle movement, imagination, creative activity etc

Cerebrospinal fluid (CSF), Liquor cerebrospinalis, is a clear bodily fluid that occupies the subarachnoid space in the brain (the space between the skull and the cerebral cortex—more specifically, between the arachnoid and pia layers of the meninges). It is basically a saline solution and acts as a "cushion" or buffer for the cortex. Cerebrospinal fluid also occupies the ventricular system of the brain and the spinal cord. It is mainly produced by the choroid plexus, but also by the ependymal lining of the brain's ventricles. The CSF is formed by the choroid plexus or the ventricles, circulates through the interventricular foramina into the third ventricle and then via the mesencephalic duct (cerebral aqueduct) into the fourth ventricle space through two lateral apertures and one median aperture, and is then absorbed by the venous system to the blood circulation.

You have your facts a little messed up. The truth is that we use all our brain. However, at any given moment, we are only using about 5% or less of our brain. This is why we can't do a million things at once and why some people have trouble chewing gum and walking at the same time. So while only 5% of our brain is in use at any given moment, there is not a single part of brain that does not perform a function and we do in fact use 100% of our brain throughout the day.

Blood flow is not constant in the brain at all times. If you're taking an exam, your cerebrum is going to be more active than if you are just laying down and resting. \n\nIn terms of exercise, the sympathetic system kicks in...increased heart rate, pupils dilated, dilation of bronchial passages, and more blood going to certain parts of the brain to be more alert and active.

Brain is the portion of the vertebrate central nervous system that is enclosed within the cranium, continuous with the spinal cord, and composed of gray matter and white matter. It is the primary center for the regulation and control of bodily activities, receiving and interpreting sensory impulses, and transmitting information to the muscles and body organs. It is also the seat of consciousness, thought, memory, and emotion. \nA functionally similar portion of the invertebrate nervous system. \n\nIntellectual ability; mind: a dull brain; a quick brain. \n\nMind the capacity of thinking, reasoning, and acquiring and applying knowledge. Mind refers broadly to the capacities for thought, perception, memory, and decision: “No passion so effectually robs the mind of all its powers of acting and reasoning as fear” (Edmund Burke). Intellect stresses knowing, thinking, and understanding: “Opinion is ultimately determined by the feelings, and not by the intellect” (Herbert Spencer). Intelligence implies solving problems, learning from experience, and reasoning abstractly: “The world of the future will be an ever more demanding struggle against the limitations of our intelligence” (Norbert Wiener). Brain suggests strength of intellect: We racked our brains to find a solution. Wit stresses quickness of intelligence or facility of comprehension: “There is no such whetstone, to sharpen a good wit and encourage a will to learning, as is praise” (Roger Ascham). Reason, the capacity for logical, rational, and analytic thought, embraces comprehending, evaluating, and drawing conclusions: “Since I have had the full use of my reason, nobody has ever heard me laugh” (Earl of Chesterfield). The human consciousness that originates in the brain and is manifested especially in thought, perception, emotion, will, memory, and imagination. \nThe collective conscious and unconscious processes in a sentient organism that direct and influence mental and physical behavior. \nThe principle of intelligence; the spirit of consciousness regarded as an aspect of reality. \nThe faculty of thinking, reasoning, and applying knowledge

The prefrontal cortex is responsible for many processes unique to higher vertebrate mammals.  I believe this would certainly have to be at least part of it.
