The brain is the most complex organ functioning of the human body. Convey orders governing the movement and getting the information that regulates thoughts and feelings.

Part of the brain. It is composed of millions of neurons responsible for receiving and sending information from the brain to all parts of the body and vice versa.

The functioning of the brain has been and is the subject of study. Although there have been many of its secrets, the expertise of some of its parts to perform different roles is still under discussion.

Central nervous system

The central nervous system is comprised of the brain and spinal cord. Normally the brain is used as a generic term, but it is actually a part of the brain.

Both the brain and the spinal cord are protected by the bones of the spine and skull. The damage to the central nervous system can have serious consequences.

Meninges

The central nervous system is protected, in addition to bone structures for three meninges. There are three membranes that prevent inter alia the entry of infectious agents in the nervous system:

·  Dura: is the most external and harder.

·  Fromed: it is the middle layer. It produces cerebrospinal fluid.

·  Elsewhere: the inner layer of the meninges.

Encéfalo

The brain is divided into the following sections:

·  Brain: is divided into two hemispheres. The external part called the cerebral cortex.

·  Cerebelo: is responsible for coordinating the activities muscle.

·  Diencéfalo: is divided into thalamus (rather than passage of nerve impulses), hypothalamus (produces certain hormones), subtálamo (related to locomotor activity) and epitálamo (produces certain hormones).

·  Bulb raquídeo: This is the body's automatic functions such as breathing, heart rate or swallow hard.

Parts of Brain

It is divided into two hemispheres asymmetrical, right and left, united by a corpus callosum. The outside of each of the hemispheres is the cerebral cortex or gray. This is a layer of a few millimeters thick composed of neurons.

On the surface of the crust there cisuras or grooves that dividing it into different areas. In each hemisphere distinguish the following areas:

·  Frontal Lobe: is responsible for the articulation movements for the production of language and is also related to emotions and personality.

·  Parietal lobe: receive information from the senses, it processed sensations like the cold or softness.

·  Temporal lobe: especially concerns the hearing and memory.

·  Occipital Lobe: in the houses mostly everything related to the hearing.

Beneath the cerebral cortex are also the four ventricles: one in each hemisphere and two between them. and two between them. For them the cerebrospinal fluid circulates.

Right Hemisferios

Scientists believe that each hemisphere specializes in any role. Thus, the right hemisphere governs the left side of his body. It specializes in everything related to the function space.

It also believes that this hemisphere depends musical and artistic perception and sensation. Scholars have arrived at these conclusions, for example, by observing the effects of damage in this area of the brain.

Left Hemisphere

Governs the right side of the body and is believed to be responsible for the role of language and writing. In this part of the brain is also the mathematical thinking and in general any logical thinking.

Scientists have found that the existence of damages in certain areas of the left hemisphere as Wernicke's area incapacitate an individual to understand the language messages received.
