Threshold Response

Threshold response is the reaction of excitable tissue in response to the action of a minimally strong (threshold) stimulus that causes excitation. A threshold stimulus is a stimulus that causes a minimal change in the physiological state of excitable tissues.

Threshold response is important for understanding the nervous system and its functions. For example, when studying the nervous system of animals or humans, threshold responses can be used to determine the minimum level of stimulation required to activate a nerve cell.

In addition, the threshold response is used in electrophysiology to study the properties of nerve cells and their response to electrical impulses. Using threshold reactions, it is possible to determine what type of stimulus causes the maximum response in a nerve cell, as well as what changes occur in its state as the strength of the stimulus increases or decreases.

Thus, threshold reactions are an important tool for studying the nervous system and are of practical importance in the medical diagnosis and treatment of diseases of the nervous system.

The threshold reaction is the response of excitable tissues to impacts that are minimally necessary to excite nerve and muscle cells. It is an important physiological process that ensures the body’s adaptation to changing environmental conditions. The threshold for the sensation of pain, the air temperature required for work, the strength of the electrical or mechanical stimulus, all these quantities are limited by sensitivity thresholds. If the stimulus does not exceed this norm, we do not perceive it. The physiological significance for stimuli in various systems of organisms is the threshold of sensations. For example, when the volume of sound and the brightness of light are beyond the thresholds of sensation, it will seem to a person that this
