Steady-state visual evoked potentials and phase synchronization in migraine [PDF]

open access: yes, 2004
We investigate phase synchronization in EEG recordings from migraine patients. We use the analytic signal technique, based on the Hilbert transform, and find that migraine brains are characterized by enhanced alpha band phase synchronization in presence ...

Visual evoked potential estimation by eigendecomposition [PDF]

open access: yes, 1998
In this paper an eigendecomposition method is presented to estimate evoked potentials (EP). Taking into account of the characteristic of evoked potentials, the method uses two observations both of which contain desired EP signal and undesired EEG signal.

Estimation of Evoked Potentials Using Wavelet Transform Based Time-Frequency Adaptive Filtering [PDF]

open access: yes, 1997
A time-frequency domain adaptive filtering method is presented to estimate evoked potentials. The wavelet transform is used to represent the original responses in the time-frequency domain with a discrete set of wavelet coefficients.

Intraoperative Neurophysiological Monitoring for Endoscopic Endonasal Approaches to the Skull Base: A Technical Guide. [PDF]

open access: yes, 2016
Intraoperative neurophysiological monitoring during endoscopic, endonasal approaches to the skull base is both feasible and safe. Numerous reports have recently emerged from the literature evaluating the efficacy of different neuromonitoring tests during

Multimodal evoked potentials and the ovarian cycle in young ovulating women [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 2000
There is controversy over how hormonal conditions influence cerebral physiology. We studied pattern-shift visual evoked potentials (PS-VEP), brain stem auditory evoked potentials (BAEP) and short-latency somatosensory evoked potentials (SSEV) in 20 ...
