Steady-state visual evoked potentials and phase synchronization in migraine patients.
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 the presence of visual stimuli. Our findings show that migraine patients have an overactive regulatory mechanism that renders them more sensitive to ext...
متن کاملTime Courses of Attentional Modulation in Neural Amplification and Synchronization Measured with Steady-state Visual-evoked Potentials
Endogenous attention modulates the amplitude and phase coherence of steady-state visual-evoked potentials (SSVEPs). In efforts to decipher the neural mechanisms of attentional modulation, we compared the time course of attentional modulation of SSVEP amplitude (thought to reflect the magnitude of neural population activity) and phase coherence (thought to reflect neural response synchronization...
متن کاملDesign Adaptable BCI Based on Evoked Potentials
In this article we deal with posibilities of adaptation in brain computer interface (BCI) systems. Main attention is given to systems based on electroencephalography (EEG). We also introduce posibilities of adaptation and improvement of performance during fatigue through combination of steady state visual evoked responses (SSVER) and event related potential P3.
متن کاملPhotic driving in migraine
In this issue of Cepkalalgia, the study by Puca et al. on steady state visual evoked potentials provides additional data confirming that hyperexcitability to light is a hallmark of the cerebral cortex in migraineurs between attacks. Since the seminal observation by Golla & Winter (1) of an increased photic drive of the EEG in migraineurs, cortical hyperreactivity to visual stimuli has been demo...
