The neurotransmitter is: the definition, functions and features
Neurotransmitters of the brain are substances about which we know little, but which affect the quality of our life, our state of health and our mood. Thanks to them, we can experience a feeling of pleasure or depression, be active or relaxed.
What are neurotransmitters?
Neurotransmitters are biochemical substances, the main function of which is the transfer of impulses between neurons. By impulse, in simplified language, information is meant, for example, a guide to action if it makes a connection between the neuron of the brain and the neuron of the muscle tissue. That is, the neurotransmitter is the mediator involved in the transfer of momentum between nerve cells. There are three systems of neurotransmitters: amino acids; peptides; monamine. Mediators from each group act on the nervous system in one way or another. For example, exciting it or hindering it.
Hormones of pleasure
Of all the neurotransmitters, serotonin and dopamine are the most familiar. They are called “pleasure hormones”, but what is meant by this term, not everyone knows.
Serotonin really is a hormone of pleasure. Its high concentration in the body causes a person a feeling of bliss, relaxation, serene joy. That is, it can be classified as a neurotransmitter with a retarding effect. Dopamine, on the contrary, encourages a person to act. But its difference from other exciting neurotransmitters is that it is developed to motivate people to perform activities that will bring a person pleasure in obtaining the result or on the way to it. Important is the fact that these neurotransmitter substances are antagonists. When a person’s dopamine level rises, serotonin falls. For example, a person plans to go in for sports and believes that after the training will experience a sense of pleasure. The increase in dopamine will prompt a person to immediately begin to work, he will be anxious when delayed.
After he performs the desired (will carry out the planned training), the level of dopamine will drop, and serotonin, on the contrary, will increase. And a person can enjoy the result of the work done. It is important that the interaction of substances does not work in the reverse order. That is, a low level of serotonin does not entail an increase in dopamine without fail.
