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 reinforce the nature of the stimulus and transmit a signal to the brain, which properly responds to it or ignores it. We can say that excitation is the main function and task of the human nervous system. It allows him to fully exist in the world, protect himself and adequately respond to certain circumstances.
After such a reaction is manifested by the body at the biological (reflex) level, it is followed by a "response" of consciousness or psyche. Images arise in our brain that testify to the nature of the stimulus, its qualities and properties. After all, excitement is the main carrier of information, and it is transmitted by external factors. And to the extent that this material is important for a particular individual, his body responds by inhibiting all processes or by an excited reaction.
Exactlyon the basis of such reactions of a person, the work of his higher nervous system is organized. During this process, the psyche, behavior in certain situations, temperament and character are formed.
In order to make it more clear, let's give a clear example and find out what inhibition and excitation are. The concept of "hot" is familiar to each of us. However, everyone has their own sensitivity threshold, therefore, the reaction has an individual character. For a man who has worked as an auto mechanic for half his life, with rough skin on his hands, it will not be a problem to lift a freshly boiled kettle without potholders. In this case, his body receives a signal that the hand is hot, but due to the fact that earlier his brain got used to the fact that the skin is rough and hardy, the first notification is blocked, i.e. the body responds with inhibition. A woman working as a manicurist will not be able to lift the same kettle without an oven mitt, and it is clear why. Her body at this moment will survive the excitement based on the fear of getting burned.
The definition of this term is also found in the psychology of relationships. For example, Mr. X has a friend for whom he has warm feelings, and an employee who is sarcastic to him, but does not cause significant damage. If a friend enters his office, Mr. X experiences emotional excitement, 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 receptorsare blocked, and although he can theoretically get excited 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 excitement is a 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 necessary, or let it go at full speed if we want to surrender to feelings and experiences. This is part of the secret of human nature, the connection of something spiritual and physical.
