How rhythmic stimulation can induce a 'sexual trance'
To reach his findings, Safron analyzed an abundance of studies and literature that have investigated the brain and body's response to sexual stimulation.

He used the information to create a model that sheds light on how rhythmic sexual activity affects rhythmic activity in the brain.

Safron explains that rhythmic sexual stimulation - if intense enough and if it lasts long enough - can boost neural oscillations at correlating frequencies, a process called "neural entrainment."
