The human brain is the central nervous system of human being and a very complex organ. Enclosed in the skull, it has the same general structure as the brains of other mammals, but more than three times larger than the brains of other mammals of equivalent body size. The most part is the cerebral cortex, a layer neuronal tissue fold covering the surface of the forebrain. Frontal lobes are the particularly extensive, which are associated with executive functions such as self-control, planning, reasoning and abstract thinking. The part of the brain associated with vision is also greatly enlarged in humans.
The brain controls and regulates the actions and reactions of the body. Continuously receives sensory information, quickly analyze this data and then responds by controlling the actions and bodily functions. The brain stem controls breathing, heart rate, and other processes independent (Deacon. 1997, pp. 337-357).
Functions
The left hemisphere is conscious, performs all functions that require analytical thinking, Elementalist and atomistic, its operation is linear, successive and sequential in time, meaning step by step, receiving the information data to data, processes it in a logical, discursive, causal and systematic verbal and mathematical way. The style of a computer where all "decision" depends on the previous mode of thinking allows you apart at a time, not all or the whole, is predominantly symbolic, abstract and propositional function, specialization and possessing almost complete control of the expression of speech, writing, arithmetic and calculation, verbal and ideational abilities, semantic, syntactic, logical and numeric.
The right hemisphere, however, is always unconscious, carries out all functions that require intellectual thought or synthetic vision and simultaneously on many things at once. Therefore, this hemisphere is equipped with an intuitive thinking that is capable of structural perceptions, syncretism, geometric configurationally or gestalt and can compare schemes on a non-verbal, analogical, metaphorical, allegorical, and comprehensive. This allows orienting in space and enables you to thinking and appreciation of spatial forms, face recognition, visual and tactile images forms, understanding pictorial, and the musical structures and, in general, anything that requires thinking visual imagination or is linked to artistic appreciation.
The working speed and information processing in both hemispheres is quite different: while the nervous system conscious rational (left brain) processes only about 40 bits (pieces of information) per second, the full capacity of the entire system unconscious Nerves (seated, mostly in the right hemisphere, the cerebellum and the limbic system) reaches from one to ten million bits per second (Kirkaldie & Kitchener, 2007, pp. 139-148).
The cerebral facilitates in pattern recognition and orientation in space is the other pillar on which the teaching of reading. It is therefore appropriate to dispose of as soon as possible before tackling it. There too many exercises in achieving this goal. Similarly, to write, the ability to hold a pencil and to control more precisely the hand gestures are necessary. They are acquired through graphic exercises setting up the brain circuits involved.
