A Time-Frequency approach for EEG signal segmentation
The record of human brain neural activities, namely electroencephalogram (EEG), is generally known as a non-stationary and nonlinear signal. In many applications, it is useful to divide the EEGs into segments within which the signals can be considered stationary. Combination of empirical mode decomposition (EMD) and Hilbert transform, called Hilbert-Huang transform (HHT), is a new and powerful ...
متن کاملUniversal automated high frequency oscillation detector for real-time, long term EEG.
OBJECTIVE Interictal high frequency oscillations (HFOs) in intracranial EEG are a potential biomarker of epilepsy, but current automated HFO detectors require human review to remove artifacts. Our objective is to automatically redact false HFO detections, facilitating clinical use of interictal HFOs. METHODS Intracranial EEG data from 23 patients were processed with automated detectors of HFO...
متن کاملHigh frequency oscillation.
It is more than 15 years since high frequency oscillatory ventilation (HFOV) was first described as a technique of ventilation [ 1 ]. In the intervening period it has passed through a phase of being a physiological curiosity, where it could be demonstrated that normal gas exchange could be maintained using tidal volumes much smaller than deadspace at rates much greater than what was then consid...
متن کاملHigh-frequency oscillation in adolescents.
BACKGROUND High-frequency oscillation (HFO) is a widely used lung-protective ventilatory strategy in paediatric and neonatal acute lung injury. Its safe and effective use has been hindered by inadequate recruitment of the lung during oscillation and, until recently, the lack of an adequately powered oscillator for use in adult practice. METHODS We present data from three adolescents with seve...
متن کاملDetectability of the somatosensory evoked high frequency oscillation (HFO) co-recorded by scalp EEG and ECoG under propofol
OBJECTIVE The somatosensory evoked potential (SEP) elicited by median nerve stimulation consists of the N20 peak together with the concurrent high frequency oscillation (HFO, > 500 Hz). We describe the conditions for HFO detection in ECoG and scalp EEG in intraoperative recordings. METHODS During neurosurgical interventions in six patients under propofol anesthesia, the SEP was recorded from ...
