Stereotactic electroencephalography-guided electrical stimulation-induced smile and laughter: a report of two cases
Journal Title: Chinese Journal of Nervous and Mental Diseases - Year 2024, Vol 50, Issue 5
Abstract
The network of laughter/smile production and propagation in the brain is not yet fully understood. In this paper, we report two cases of medically refractory epilepsy patients with stereotactic EEG implantation, in which smiles (without pleasurable emotions and motor awareness) and laughter (with situationally incompatible pleasurable emotions) were repeatedly induced by electrical stimulation in the left precentral gyrus, and the right insular short gyrus, respectively. This phenomenon reflects the existence of distinct and linked emotional and behavioral networks for laughter.
