Key Moments
Hypnosis reduces activity in the brain's salience network to lower anxiety
Dr. Spiegel explains that during hypnosis, activity in the dorsal anterior cingulate cortex decreases, which is part of the salience network responsible for pattern matching and threat detection. This automatic reduction quiets the brain's alarm system and reduces stress.
"the more hypnotized they are, the more they turn down activity in a part of the brain called the dorsal anterior cingulate cortex"
Hypnosis strengthens the brain-body connection through the insula
The second brain change during hypnosis is increased functional connectivity between the prefrontal cortex and the insula, creating stronger mind-body control and enhanced interoception for sensing what is happening in the body.
"one brain region is active the other one"
Hypnosis suppresses the default mode network to enable behavioral change
Dr. Spiegel describes the third brain mechanism of hypnosis as inverse connectivity with the posterior cingulate cortex, which he calls the "my fault mode network." Suppressing this region allows people to let go of rigid self-concepts and try new behaviors.
"singulate. That's part of what we call"
