Human Intracranial High Frequency Oscillations (HFOs) Detected by Automatic Time-Frequency Analysis
Sergey Burnos,Peter Hilfiker,Oguzkan Sürücü,Felix Scholkmann,Niklaus Krayenbühl,Thomas Grunwald,Johannes Sarnthein +6 more
TL;DR: Compared to methods detecting energy changes in filtered signals, this second stage - analysis in the time-frequency domain - discards spurious detections caused by artifacts or sharp epileptic activity and improves the detection of HFOs.
Journal ArticleDOI
Resection of high frequency oscillations predicts seizure outcome in the individual patient.
Tommaso Fedele,Sergey Burnos,Sergey Burnos,Ece Boran,Niklaus Krayenbühl,Peter Hilfiker,Thomas Grünwald,Johannes Sarnthein +7 more
TL;DR: The resection of the prospectively defined HFO area proved to be highly specific and reproducible in 13/13 patients with seizure freedom, while it may have improved the outcome in 4/7 patients with recurrent seizures.
Journal ArticleDOI
Persistent hippocampal neural firing and hippocampal-cortical coupling predict verbal working memory load
Ece Boran,Tommaso Fedele,Tommaso Fedele,Tommaso Fedele,Peter Klaver,Peter Klaver,Peter Hilfiker,Lennart Stieglitz,Thomas Grünwald,Johannes Sarnthein,Johannes Sarnthein +10 more
TL;DR: It is found that persistent neural activity in the hippocampus participated in working memory processing that is specific to memory maintenance, load sensitive and synchronized to the cortex.
Journal ArticleDOI
Prediction of seizure outcome improved by fast ripples detected in low-noise intraoperative corticogram
Tommaso Fedele,Georgia Ramantani,Sergey Burnos,Peter Hilfiker,Gabriel Curio,Thomas Grünwald,Niklaus Krayenbühl,Johannes Sarnthein,Johannes Sarnthein +8 more
TL;DR: In this article, the authors proposed the integration of low-noise EEG with unsupervised fast ripples (FR, 250-500Hz) in the intraoperative corticogram.
Journal ArticleDOI
Dynamic human and avatar facial expressions elicit differential brain responses.
Lorena Chantal Kegel,Peter Brugger,Sascha Frühholz,Thomas Grünwald,Peter Hilfiker,Oona Kohnen,Miriam Laura Loertscher,Miriam Laura Loertscher,Dieter Mersch,Anton Rey,Teresa Sollfrank,Bettina K. Steiger,Joerg Sternagel,Michel Weber,Hennric Jokeit +14 more
TL;DR: In this article, the human brain processes fearful and neutral expressions in human and avatar faces differently and found that fearful human expressions evoked stronger responses than fearful avatar expressions in the ventral anterior and posterior cingulate gyrus, the anterior insula, the posterior superior temporal sulcus, and the inferior frontal gyrus.
