Insular Stimulation Produces Mental Clarity and Bliss

Abstract

For the first time, an ecstatic aura has been evoked through the electrical stimulation of the dorsal anterior insula during presurgical invasive intracerebral monitoring in a patient who did not suffer from an ecstatic form of epilepsy. This case provides more evidence that the anterior insula is the major generator of such a mystical-type experience even in individuals with no underlying brain network changes related to a preexisting ecstatic epilepsy.
