Signal System First

The Signal First system is a system of conditioned reflex connections formed in the cerebral cortex of animals and humans when exposed to specific stimuli (light, sound, etc.). The Signal First system is responsible for the orienting reflex and is aimed at analyzing the novelty and significance of stimuli. It allows the body to respond to significant changes in the environment.

The formation of the Signal First System occurs in the process of learning and gaining experience. The more new signals the brain receives, the stronger this system of connections develops. Her work is closely related to attention and consciousness. The signaling system plays an important role in the adaptation of the body to environmental conditions.

The Signal First system is an example of conditioned reflexes, i.e. internal connections between the body and the external environment, developed under the influence of environmental signals. This is an example of biosocial communication in the animal kingdom. The main factor of the Signal Second system is the food factor.

The Signal First system is one of the most important systems in our body and regulates many aspects of our lives. When we see something tasty or hear tasty sounds, our Signal Second system reacts and makes us want to eat that food. It also stimulates the production of pleasure hormones: dopamine and serotonin. Hormones create the illusion that food is “tasty” and that the body has received enough nutrients. Subsequent hunger is no longer the satisfaction of receiving food, but the body’s habit of receiving this pleasure again and again. It can be a large amount of fatty, sweet and high-calorie foods that lead to obesity. Each such meal helps people feel better only for a while, but soon the feeling of hunger still sets in. By changing your lifestyle, you can avoid this feeling for a long time. Although it may be difficult at first, taking care of your health will eventually reward you with improved well-being.
