Removing high-frequency oscillations: A prospective multicenter study on seizure outcome

Julia Jacobs, +8 more
- 11 Sep 2018 - 
TL;DR: Evaluating the use of interictal high-frequency oscillations in epilepsy surgery for prediction of postsurgical seizure outcome in a prospective multicenter trial found HFOs may be less specific for epileptic tissue than earlier studies have indicated.
Journal ArticleDOI

High-frequency oscillations are not better biomarkers of epileptogenic tissues than spikes.

Nicolas Roehri, +8 more
- 01 Jan 2018 - 
TL;DR: This work investigated how well HFOs and spikes can predict epileptogenic regions with a large spatial sampling at the patient level.
Journal ArticleDOI

Changing concepts in presurgical assessment for epilepsy surgery

Maeike Zijlmans, +2 more
- 01 Oct 2019 - 
TL;DR: The importance of looking beyond the EEG seizure onset zone and considering focal epilepsy as a brain network disease in which long-range connections need to be taken into account is highlighted, and how new diagnostic techniques are revealing essential information in the brain that was previously hidden from view is explored.
Journal ArticleDOI

Resection of high frequency oscillations predicts seizure outcome in the individual patient.

Tommaso Fedele, +7 more
- 23 Oct 2017 - 
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.

Localization of the Epileptogenic Zone Using High Frequency Oscillations

Aljoscha Thomschewski, +2 more
- 12 Feb 2019 - 
TL;DR: High-frequency oscillations are suggested to be a promising biomarker of the EZ, with a potential to improve surgical success in patients with drug-resistant epilepsy without the need to record seizures, but in order to establish HFOs as a clinical biomarker, the following issues need to be addressed.

Localization of the complex spectrum: the S transform

R. G. Stockwell, +2 more
- 01 Apr 1996 - 
TL;DR: The S transform is shown to have some desirable characteristics that are absent in the continuous wavelet transform, and provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum.

Localisation of the complex spectrum : The S transform

R. G. Stockwell, +2 more
- 01 Jan 1996 - 
TL;DR: The S transform as discussed by the authors is an extension to the ideas of the Gabor transform and the Wavelet transform, based on a moving and scalable localising Gaussian window and is shown here to have characteristics that are superior to either of the transforms.

Wavelet entropy: a new tool for analysis of short duration brain electrical signals.

Osvaldo A. Rosso, +6 more
- 30 Jan 2001 - 
TL;DR: The major objective of the present work was to characterize in a quantitative way functional dynamics of order/disorder microstates in short duration EEG signals with specific quantifiers derived to characterize how stimulus affects electrical events in terms of frequency synchronization (tuning) in the event related potentials.

Quantitative analysis of high-frequency oscillations (80-500 Hz) recorded in human epileptic hippocampus and entorhinal cortex.

Richard J. Staba, +4 more
- 01 Oct 2002 - 
TL;DR: The strong association between FR and regions of seizure initiation supports the view that FR reflects pathological hypersynchronous events crucially associated with seizure genesis.

High-frequency electroencephalographic oscillations correlate with outcome of epilepsy surgery.

Julia Jacobs, +7 more
- 01 Feb 2010 - 
TL;DR: This work investigated whether HFOs can delineate epileptogenic areas even outside the SOZ by correlating the resection of HFO‐generating areas with surgical outcome.
