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.

The patient reported orgasmic ecstasy following the stimulation of the left hippocampus (Hipp) at 3 mA. This stimulation was followed by an 18-second afterdischarge over the left hippocampus (Hipp), the parahippocampal gyrus (PHG), the temporal pole (T pole), and the anterior-inferior insula (aINS).

f0010: The patient reported orgasmic ecstasy following the stimulation of the left hippocampus (Hipp) at 3 mA. This stimulation was followed by an 18-second afterdischarge over the left hippocampus (Hipp), the parahippocampal gyrus (PHG), the temporal pole (T pole), and the anterior-inferior insula (aINS).

Mentions: As part of the intracranial EEG monitoring study, electrical stimulation was performed for cortical mapping and for the identification of contacts which could reproduce the patient's auras. The parameters used were as follows: stimulus frequency of 50 Hz with a pulse width of 100 ms, a stimulus intensity of 1–10 mA, and a stimulus train duration of 5 s (Grass S88 Stimulator, Grass Instruments, Natick, MA). Stimuli were administered with an intervening rest interval of at least 1 min, and afterdischarges were assessed at each stimulation. The patient reported an OE following the stimulation of the left hippocampus at 3 mA. This stimulation was followed by an 18-second afterdischarge over the left hippocampus, the parahippocampal gyrus, and the anterior-inferior insula (Fig. 2). The identical sensation was reproduced when stimulation was repeated a second time at 3 mA with a similar 17-second afterdischarge. Stimulation of the right hippocampus at 1 mA generated the same orgasmic sensation while triggering a 45-second seizure discharge over the right hippocampus, parahippocampal gyrus, temporal pole, and anterior insula (Fig. 3). In the end, no resection was performed as spontaneous seizures were found to originate from both right and left hippocampi as well as the left temporal neocortex and the left cuneus.
