Summary
We provide here a functional mapping of the insular cortex obtained by electrical stimulation carried out during stereo-electro-encephalography (SEEG). Somatosensory sensations and visceral responses were the most frequent responses to insular stimulation, followed in decreasing order of frequency by auditory sensations, vestibular illusions, speech impairment, gustato-olfactory sensations, and motor reactions. The posterior part of the insula seems more implicated in somatosensory functions, notably in pain perception, whereas the anterior part seems more implicated in visceral functions. Although some degree of spatial segregation could be evidenced, there was a clear spatial overlap between the representations of the different types of responses. Electrical stimulations permit to evidence a singularly multi-modal representation in the insula that may support its integrative functions of polymodal inputs. They also provide a better understanding of physiological insular functions and the semiology of insular seizures.
