The reproducibility of FVEP and the amplitude of the concomitant EEG from C4Fz were measured. Nine patients had low amplitude EEG (50 V); FVEPs were absent from three of four eyes with normal pre-operative vision (the other normal eye had a present but irreproducible FVEP). Raising the ...
Researchers recommend that the VLF band is fundamentally produced by the heart and represents good health and wellbeing and its rhythmic amplitude and frequency patterns are influenced by the efferent sympathetic activities and physical activities (Berntson et al., 1997a,b; Bernardi et al., 1996)....
An EEG study in healthy individuals investigating oscillatory activity in the ACI employed 3 Hz amplitude-modulated tones that were either interrupted or continuous20. Moreover, during the period of interruption, a noise that was either partially masking the tone (i.e. with a spectral gap in ...
Electroconvulsive therapy (ECT) at conventional current amplitudes (800–900 mA) is highly effective but carries the risk of cognitive side effects. Lowering and individualizing the current amplitude may reduce side effects by virtue of a less intense
To obtain the instantaneous amplitude of the high-frequency rhythm during tACS we subtract the harmonic fit (Supplementary Fig.4) and filtered the residual iEEG signal with a complex-valued Morlet bandpass for spindle activity (fc = 14 Hz, bandwidth = 7 Hz), for alpha activity ...

Whereas amplitude EEG (aEEG) recording has gained wide acceptance in intensive care units to identify term infants at risk of neonatal encephalopathy, its use in extremely low birth weight (ELBW; birth weight <1000 g) infants remains less clear.Chalak, L...
Relative alpha power in resting state for pre- and post-test was calculated by dividing the absolute power in the alpha frequency range (8-12 Hz) by the baseline. This approach helps to minimize inter-individual differences in EEG signal amplitude, better reflects the contribution of alpha os...
Likely, working memory-associated differences in alcohol effects on inhibition are expressed in a relative synchronization of alpha and theta frequency band dynamics. These effects are likely to occur during the actual process of response inhibition. Several lines of evidence show that EEG correlates ...
