The sensorimotor cortex is the access of physical sensations to the brain. It sends a signal to the limbic system / amygdala to trigger the pain reaction and, if necessary, to release stress hormones.
When no corresponding pain signal passes on, no pain should arise. The pain treatment attempts to "manipulate" the sensorimotor cortex by provoking a kind of "resting brain wave" that restricts the sensorimotor cortex in its activity, thus ensuring that incoming pain signals "go unheard".
Here is a large area with sometimes very different tasks.
Clinical hypnosis is also one of the oldest and most effective methods of psychological pain control. It changes the perception of a person's perception of reality and is therefore very suitable for changing part of that perception, namely of pain, which is caused by certain wiring patterns in the brain. This interconnection pattern must be broken up and a new pattern practiced.
In chronic pain is a long-term treatment as "in trance, you can get patients relatively easily painless, but they must learn to integrate these pain-free experiences in everyday life”.
At the end, the behavioural therapy patient does not differ from the hypnosis client; both have to do their homework. The best thing for the patient to do is to go into a trance for themselves every day, to practice the same processes as in the treatment.
