High frequency oscillations (HFOs) recorded through electroencephalography (EEG) have recently emerged as putative biomarkers of epileptogenicity [1]. HFOs are transient events that likely reflect synchronized activity of neuronal populations [2]. These phenomena are subdivided according to their spectral range into “ripples” (approximately 80-250 Hz) and “fast ripples” (FRs, approximately 250-500 Hz) [3]. HFOs can be both pathological or physiological, contributing to epileptogenesis or eloquent cognitive functions [2].
