Excitation is a standard reaction of any living organism to an external stimulus. As a rule, excitable tissue, on which the most sensitive receptors are located, is responsible for such a reaction. They fix the nature of the stimulus and transmit a signal to the brain, which properly responds to it or ignores it. We can say that arousal is the main function and task of the human nervous system. It allows him to fully exist in the world, to protect himself and to adequately respond to certain circumstances.
After a similar reaction is manifested by the body at a biological (reflex) level, it is followed by a “response” of consciousness or psyche. In our brain, images appear that indicate the nature of the stimulus, its qualities and properties. After all, arousal is the main medium of information, and it is transmitted by external factors. And as far as how important this material is for a particular individual, his body responds with inhibition of all processes or an excited reaction.
It is on the basis of such human reactions that the work of his higher nervous system is organized. In the course of this process, the psyche, behavior patterns in certain situations, temperament and character are formed.
In order to make it more clear, we give a clear example and find out
what is inhibition and excitement. The concept of "hot" is familiar to each of us. However, the threshold of sensitivity for each has its own, therefore, the reaction has an individual character. For a person who has worked as a car mechanic for half his life, whose skin is hardened on his hands, it will not be a problem to lift a kettle that has just boiled without a tack. In this case, his body receives a signal that the hand is hot, but due to the fact that earlier his brain was used to the fact that the
skin is rough and hardy, the first notification is blocked, that is, the body responds with inhibition. A woman working as a manicurist will not be able to raise the same kettle without a tack, and it is understandable why. Her body at this moment will survive the excitement based on fear to burn itself.
The definition of this term is also found in the psychology of relationships. For example, Mr. X has a friend to whom he feels warm feelings, and an employee who ulcerates him, but does not cause significant damage. If a friend enters his office, Mr. X experiences emotional arousal, his tone and mood increase, and pleasant associations arise. At the entrance of an envious employee (if Mr. X is rational and prudent, and does not respond to provocations), his nerve receptors are blocked, and although he can theoretically be aroused and respond with the same “poison”, his body begins to “slow down”, and as a result he does not pay attention to anything.
In general, we can say that arousal is a chemical-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 necessary, or let it go at full speed if we want to surrender to feelings and feelings. This is part of the secret of human nature, the connection of something spiritual and physical.
