Physiology of sensory systems

Abstract

The existence of a living organism is impossible without information, which must come both from the outside world and from the internal environment. Both streams of information interact and are carried out thanks to the functioning of special systems - sensor systems. They transform adequate stimuli into nerve impulses that go to the central nervous system. At different levels of the brain, this information is filtered, analyzed, recognized and transformed into sensory sensations that are perceived and an image of the stimulus is created. Thus, sensory systems are structures that ensure the perception of information, its processing through analysis and synthesis, create an image of a stimulus based on its features and sensory experience and form a conscious feeling. What is the role of sensory information? The work of all internal organs is organized on the basis of sensory information. It is also an important condition for the activity of a person, one’s formation and development as an individual. Sensory information is an important factor in the formation of human behavior, its adaptation to the conditions of existence.
