The intrinsic brake is a mechanism in the nervous system that allows you to regulate the activity of neuronal cells and control their response to external stimuli. It plays an important role in regulating behavior and adapting the body to changing environmental conditions.
Internal inhibition can occur both in response to external stimuli and as a result of internal processes, such as changes in hormone levels or metabolic processes. For example, during physical activity or stress, the sympathetic nervous system is activated, which leads to an increase in the level of adrenaline and norepinephrine in the blood. These hormones can cause inhibition in certain areas of the brain, which helps the body adapt to new conditions and conserve energy.
In addition, internal inhibition can be caused by internal processes, such as changes in serotonin or dopamine levels. Serotonin, for example, is involved in the regulation of sleep and wakefulness, and dopamine in motivation and learning. Changes in the levels of these hormones can lead to inhibition of certain neural pathways and decreased activity in certain areas of the brain.
Finally, internal inhibition can also arise from learning and experience. For example, if a person receives a negative experience as a result of some event, this can lead to inhibition of the corresponding neural pathways and a decrease in the response to this stimulus in the future.
In general, the internal brake plays an important role in regulating nervous activity and adapting the body to external conditions. It allows us to adapt to a changing environment and conserve energy to perform necessary functions.
Internal inhibition is a type of conditioned reflex that occurs as a result of the influence of some cause that causes protective excitation in the central nervous system. It occurs under strong distractions, inappropriate conditions, and inappropriate stimuli. There are two types of internal inhibition: sentinel and transcendental inhibition. Sentinel temporary conditioned reflexes are developed under the same conditions. Their preservation is possible due to the action of other reflex reactions, which lower the threshold upon repeated perception of the same stimulus. If at this moment there is no stimulus, then the behavior of the body’s reflex system consists of assessing the internal situation and action, which does not lead to the emergence of a temporary isolated reflex. In the absence of excitation, internal inhibition is formed. Transcendental temporary reflexes - when exposed to a large amount of varied information, extreme inhibition develops, interfering with the functioning of the brain. There is a decrease or loss of performance. If possible, resting the nervous system is avoided.
