Crying with sorrow evoked by electrocortical stimulation

Abstract

Dacrystic seizures are rare and have been reported in patients with hypothalamic hamartoma as well as fronto-temporal epilepsy, involving the non-dominant hemisphere. We describe the first reported case of cortical stimulation of the left posterior orbito-frontal gyrus, generating consistent and reproducible crying with affective content in a 41-year-old woman with medically intractable left temporal lobe epilepsy, who underwent extraoperative intracranial video-EEG monitoring for resective non-lesional epilepsy surgery.
