The excitation is a signal. What?

Excitement – is the standard reaction of any living organism to an external stimulus. As a rule, a similar reaction is responsible excitable tissue, which is the most sensitive receptors. They reinforce the nature of the stimulus and transmit signal to the brain that it properly responds or ignores it. We can say that the excitation – this is the main function and task of the human nervous system. It allows him to fully exist in the world, to protect itself and to respond appropriately to certain circumstances.

After this reaction is manifested by an organism at a biological (reflex) level, followed by “response” consciousness, or the psyche. In our brain there are images that show about the nature of the stimulus, its quality and properties. After all the excitement – is the main carrier of information, and it is transmitted to the external factors. And the measure of how important this material is for a particular individual, the body responds by deceleration of all processes, or nervous reaction.

It is through such reactions can be its higher nervous system. In this process, formed the psyche, behavior in certain situations, temperament and character. In order to make it more clear, let's consider an example and see what is inhibition and excitation. The concept of “hot” familiar to all of us. However, the sensitivity threshold is for everybody, and therefore the reaction has an individual character. For a man who spends half his life worked as a mechanic at the hands of callous skin, not a problem to lift without a pot just boiling the kettle. In this way his body gets the signal that the hand is hot, however, due to the fact that earlier his brain got used to the fact that the skin is rough and tough, the first notice is blocked, i.e. the body responds by braking. To raise the same kettle without potholders can't woman working as a manicurist, and I understand why. Her body at this moment will survive based on fear of getting burned excitation.

The Definition of this term found in the psychology of relationships. For example, Mr. X has a friend who has a warm feeling, and the employee who stings him, but not crippling. If his study included friend, Mr. X is experiencing emotional arousal, he increased the tone and mood, associated. At the entrance of the employee-envious (if Mr. X is rational and reasonable, and not responding to provocation) his neural receptors are blocked, and although it theoretically may be possible to meet the same “poison”, his body begins to “slow”, and as a result he doesn't pay attention to anything.

In General we can say that the excitation – chemical and biological process that begins in the microscopic cells of our nervous tissue, and ends in temperament, habits and worldview. We know how to block it when you need it, or to indulge in a full course, if you want to surrender to the feelings and experience. This is part of the secret of human nature, when something spiritual and physical.
