Induction Positive

Positive induction: what is it and how does it work?

Positive induction is a process that occurs in the nervous system of humans and animals. It consists in increasing the excitability of nerve centers that are located next to the source of inhibition. Positive induction is one of the mechanisms of adaptation of the nervous system to changing environmental conditions.

How does positive induction work?

Positive induction occurs due to the fact that the excitation of nerve cells spreads to adjacent nerve centers. In this case, the signal is amplified in neurons that are located next to the focus of inhibition. Thus, the excitability of these neurons increases, which contributes to more efficient transmission of nerve impulses in synaptic contacts between neurons.

An example of positive induction is an increase in the force of muscle contraction. When the muscle is repeatedly stimulated after a certain time interval after the first stimulus, muscle contraction increases due to positive induction.

Also, positive induction can manifest itself in the field of vision. For example, if a flickering light signal appears on the monitor screen, then when this signal appears again after some time, its brightness increases, which is associated with positive induction.

Conclusion

Positive induction is an important function of the nervous system, which ensures its adaptation to changing environmental conditions. Thanks to positive induction, it is possible to increase the efficiency of transmission of nerve impulses and increase the strength of muscle contraction. Although the mechanisms of positive induction are not fully understood, this function of the nervous system has already found its application in medicine and science.

Positive induction is a phenomenon in which the excitation of the centers of the nervous system adjacent to the area of ​​inhibition leads to an increase in their excitability. This can be caused by various factors, such as increased stimulation, decreased inhibitory effect, or a change in the chemical composition of the environment. Positive induction can lead to increased reflex responses, improved memory and concentration, and increased brain efficiency.

In medicine, positive induction is used to treat various diseases such as depression, anxiety disorders and sleep disorders. It can also be used to improve cognitive function in people who have difficulty learning or working.

However, positive induction can also have negative consequences, such as increased excitation of the nervous system and an increased risk of developing epilepsy. Therefore, it is necessary to use positive induction with caution and only under the supervision of a physician.
