The human Brain, even today, remains a real mystery to researchers. However, much they have managed to find out. So what “the wire” the brain receives messages, and based on what?

The Principle of operation of the human brain

The Brain of a Mature man weighs about four pounds, where “fit” about the hundreds of billions of active cells. Most of the cells – it's the neurons that serve as conductors of nervous impulses.

what wires the brain receives the message

How the brain works? The principle of its activities can be roughly compared with the operation of the electric switch. Neurons can be in “off” and “enabled” condition, when the electric pulses are transmitted on corresponding conductive paths.

Generated neurons in the cell body and transmit nerve impulses axons. In turn, neural axons, connected by synapses, which occurs due to the transmission of information between individual neurons.

The Role of chemicals in the brain activity

brain structure and function

Features of the human brain involve the activity of special chemical compounds, known as neurotransmitters. The presence of substances such as dopamine or epinephrine, helps to activate certain functions. And different departments, as well as their neurons, “apply” in their work, the different chemical components.

Due to the chemical activity of the brain, its neurons are able to reproduce the electric charge, the capacity of which in General can reach about 60 watts. Brain activity based on electrical activity can be measured with specialized equipment.

What “the wire” the brain receives the message?

The Main guide to transmit information to the neurons through the nerve synapses acts as the spinal cord. To compare pathways of the spinal cord possible with a multi-conductor telephone cable. Damage to such "cable" could lead to loss of human control over individual limbs and body in General. It is through electrical impulses to transmit commands to the brain of the body.

Bypassing the synapses of the spinal cord directly into the brain the information is transmitted only from the auditory and visual receptors. That is why when paralysis of the whole body, the person retains the ability to hear and see.

brain activity

In General the brain activity caused by the functioning of the grey matter, which is located on its surface and forms the cerebral cortex. A special role in the brain plays a white substance that is almost entirely composed of conducting impulses axons.

The Brain: structure and function

The Human brain formed of two hemispheres-left and right, which are responsible for certain functions. Thus, the right hemisphere of the human brain allows you to group incoming information. In turn, the left hemisphere is vested in the “inbound” data. For example, the right hemisphere identificeret the subject, and the left defines its features, qualities, characteristics, etc.

brain

What “the wire” the brain receives messages? According to researchers, receiving electrical impulses, the right hemisphere of the brain perceives mostly abstract things and concepts, analyzes form and color. At the same time, the left hemisphere reserves mathematical ability, speech, and logic. From year to year, scientists find such a specific separation of the functions of the human brain and its differentiation all new confirm.

Myths about the human brain

Today it remains a common view that modern man can not use more than 10% of their brain. Despite numerous disputes around this matter, there is a whole lot of evidence of human use of the full potential of the brain. According to researchers, even doing fairly simple tasks needs to enhance virtually all regions of the brain.

features of the brain

It is also a myth to believe that blind people hearing better developed compared to the sighted. However, the blind can boast a more developed auditory memory. Such people faster identificeret the sources of sounds, and actively catch the meaning of the foreign language.

Brain Size has absolutely no effect on intellectual ability. The determining factor in the development of intelligence becomes only the number of neural connections between individual neurons.

Interesting facts about the brain

The Man is difficult to tickle yourself. It's all in the spirit of the brain on the perception of stimuli from the outside world, allowing you to select really important for the body signals from the vast flow of feelings. Because the cause of most of them are unconscious actions of a person.

Yawning is not simply a conditioned reflex, withdrawal from sleep, but also allows the brain to come to an active state, due to its active oxygen.

Computer games give the brain a rest and relaxation at the expense of distraction from everyday problems and also teach the simultaneous execution of several tasks simultaneously. And the best exercise of the brain in this case are active games for example action games and shooters when the player has to repel the attacks of a whole group of enemies that come from different angles in confined spaces. Participation in such virtual play allows a person to instantly react to a fast changing situation and to disperse the attention.

brainExercise will help you maintain the brain in good shape. Regular physical activity affect the growth in the number of capillaries in the brain that gives the ability to better saturate it with nutrients and oxygen.

A Simple song with no complex musical structure and the special meaning it is much harder to forget than with a really “intellectual” works. The reason lies in the brain's ability to build an automatic, habitual actions, which can incorporated such melodies.

In conclusion

The Human brain is an extremely complex structure, which includes a lot of functional departments, which are based on strengthening and damping of billions of neurons.

What “the wire” the brain receives messages? The role of such pathways perform neural connections. Each neuron acts like a microscopic electrical switch, the inclusion of which stimulates the transmission of nerve impulses in the right parts of the brain. Coming from the external world the information ultimately transmitted in the large hemispheres of the brain, where it is the final analysis and processing.
