A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. Physiologically, brains exert centralized control over a body's other organs. They act on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain. The operations of individual brain cells are now understood in considerable detail but the way they cooperate in ensembles of millions is yet to be solved. Recent models in modern neuroscience treat the brain as a biological computer, very different in mechanism from an electronic computer, but similar in the sense that it acquires information from the surrounding world, stores it, and processes it in a variety of ways. This article compares the properties of brains across the entire range of animal species, with the greatest attention to vertebrates. It deals with the human brain insofar as it shares the properties of other brains. The ways in which the human brain differs from other brains are covered in the human brain article. Several topics that might be covered here are instead covered there because much more can be said about them in a human context. The most important is brain disease and the effects of brain damage, that are covered in the human brain article.
the whitish mass of soft matter (the center of the nervous system, and the seat of consciousness and volition) which is inclosed in the cartilaginous or bony cranium of vertebrate animals. It is simply the anterior termination of the spinal cord, and is developed from three embryonic vesicles, whose cavities are connected with the central canal of the cord; the cavities of the vesicles become the central cavities, or ventricles, and the walls thicken unequally and become the three segments, the fore-, mid-, and hind-brain
the anterior or cephalic ganglion in insects and other invertebrates
the organ or seat of intellect; hence, the understanding
the affections; fancy; imagination
to dash out the brains of; to kill by beating out the brains. Hence, Fig.: To destroy; to put an end to; to defeat

The brain is the center of the nervous system in all vertebrate and most invertebrate animals—only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have one, even if diffuse neural tissue is present. It is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain of a vertebrate is the most complex organ of its body. In a typical human the cerebral cortex is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information-integrating capabilities of a centralized brain.
Chambers 20th Century Dictionary
brān, n. the term applied to that part of the central nervous system which in vertebrated animals is contained within the cranium or skull, and in the invertebrata, to the nervous ganglia near the head end of the body: the seat of the intellect and of sensation: the intellect.—v.t. to dash out the brains of: (Shak.) to conceive of.—n. Brain′-cor′al, the popular name of certain kinds of coral, so called from their general resemblance to a brain.—p.adj. Brained, having brains.—n. Brain′-fe′ver, a loose popular term which includes congestion of the brain and its membranes, delirium tremens, and inflammation of the brain substance itself.—adjs. Brain′ish (Shak.), brain-sick, hot-headed, furious; Brain′less, without brains or understanding: silly.—n. Brain′-pan, the skull.—adj. Brain′-sick, diseased in the understanding, deranged.—adv. Brain′sick′ly (Shak.).—n. Brain′-sick′ness. [A.S. brægn; Dut. brein, prov. Ger. bregen]
The Roycroft Dictionary
A commodity as scarce as radium and more precious, used to fertilize ideas.
U.S. National Library of Medicine
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
The Foolish Dictionary, by Gideon Wurdz
The top-floor apartment in the Human Block, known as the Cranium, and kept by the Sarah Sisters--Sarah Brum and Sarah Belum, assisted by Medulla Oblongata. All three are nervous, but are always confined to their cells. The Brain is done in gray and white, and furnished with light and heat, hot or cold water, (if desired), with regular connections to the outside world by way of the Spinal Circuit. Usually occupied by the Intellect Bros.,--Thoughts and Ideas--as an Intelligence Office, but sometimes sub-let to Jag, Hang-Over & Co.

The brain cannot be in two places at once, so what people are referencing as multitasking is actually what neuroscientists call task switching and that means rapidly moving back and forth between different tasks.
I would speculate that it is an effect that lasts, the brain develops rapidly from zero to six years of age, and the more exposure, the more you enrich and nurture these brain networks that are related to social and academic ability, the more the kid will gain the future.
I am willing to be persuaded into seeing any other person's perspective as long as they possess, at the very least, two properly functioning brain cells. Unfortunately, this is a rare commodity.
