Functional Mapping of Emotion Recognition in Epilepsy Patients: An Intracranial EEG Study

Popis výsledku v původním jazyce

Purpose:Resection of brain areas involved in emotionprocessing could lead to a more rapid decline of cognitivefunctions, specifically in the domain of emotion recogni-tion. Our aim was to map brain structures involved in emo-tion recognition by intracranial electroencephalography(EEG).Method:We examined 15 pharmacoresistant epilepsypatients undergoing intracranial EEG monitoring as a partof their presurgical evaluation. We used both visual (theEkman-Friesen set of faces) and auditory emotional stimuli,and, as a control stimuli, photos and sounds of musicalinstruments (violin and piano). We identified intracranialelectrodes with significantly different reaction (P < 0.01) inhigh-gamma band (60–120 Hz) after stimulus presentationto the emotional stimuli in comparison to musical instru-ments.Results:For facial emotions, significantly more activationswere consistently found in inferior and middle temporalgyri, and inferior frontal gyrus (especially pars triangularis).For the auditory stimuli, middle temporal gyrus and pla-num temporale were more activated for emotional soundsthan for the musical instruments. In superior temporalgyrus, different sites of activations were found for emo-tional and non-emotional stimuli. Lingual and middle fron-tal gyri were more activated by images of musicalinstruments than by facial emotions.Conclusion:We found a complex network involved inrecognition of emotional stimuli and also different struc-tures involved in emotion recognition from image andsound. Thus, such emotion-specific activations could beused in the future as a potential biomarker of critical brainstructures to prevent postoperative deficit in emotion recog-nition.
