Bilateral cortical representation of orgasmic ecstasy localized by depth electrodes.

Surbeck W, Bouthillier A, Nguyen DK - Epilepsy Behav Case Rep (2013)

Bottom Line: While sexual arousal had been evoked during direct electrical stimulation (DES) of the right mesial temporal lobe and basal forebrain, isolated orgasmic ecstasy (OE) evoked by DES is not reported in the literature.We present the first case of isolated bihemispheric reproduction of OE by stimulation via depth electrode in a patient implanted for epilepsy.

Mentions: The patient was a 49-year-old, right-handed woman with no significant past medical history except for medically intractable epilepsy since age 15 years. Seizures were characterized by altered consciousness and oral automatisms followed by postictal confusion. While some seizures were not preceded by any aura, some may start with visual symptoms (flashing lights), déjà vu, or an orgasmic feeling. Secondarily tonic-clonic seizures were rare. Magnetic resonance imaging showed a very discrete atrophy of the left hippocampus. Video-scalp electroencephalography (EEG) monitoring disclosed bilateral temporal spikes. Several seizures were recorded with diffuse EEG changes and maximum build-up more frequently over the left than the right temporal region. FDG PET was normal. Suspecting a possible posterior focus with propagation to the temporal lobes, an invasive electrode study was subsequently performed. A total of 6 depth electrodes, 15 subdural strip electrodes and a small subdural grid electrode were inserted to sample the medial, lateral, inferior, and posterior temporal regions and the insular, occipital, parietal, and inferior frontal regions bilaterally (Fig. 1).
