Nonlinear Time Series Analysis of Human Alpha Rhythm
, 2002
"... Nonlinearity is often deduced by showing that a dataset signicantly deviates from its phase randomized versions, i.e. surrogate data. For real data, however, non-stationarities like artifacts and onsets and offsets of rhythmic activity will cause false positives. We propose a new test which detects ..."

Nonlinearity is often deduced by showing that a dataset signicantly deviates from its phase randomized versions, i.e. surrogate data. For real data, however, non-stationarities like artifacts and onsets and offsets of rhythmic activity will cause false positives. We propose a new test which detects dynamical nonlinearity by measuring time-asymmetry, using surrogate data merely to estimate the standard deviation of the process.

The Effect of Alpha Rhythm Sleep on EEG Activity and Individuals ’ Attention
"... Abstract. [Purpose] This study examined whether the alpha rhythm sleep alters the EEG activity and response time in the attention and concentration tasks. [Subjects and Methods] The participants were 30 healthy university students, who were randomly and equally divided into two groups, the experimen ..."

Spontaneous Slow Fluctuation of EEG Alpha Rhythm Reflects Activity in Deep-Brain Structures: A Simultaneous EEG-fMRI Study
, 2013
"... The emergence of the occipital alpha rhythm on brain electroencephalogram (EEG) is associated with brain activity in the cerebral neocortex and deep brain structures. To further understand the mechanisms of alpha rhythm power fluctuation, we performed simultaneous EEGs and functional magnetic resona ..."

Pre- and poststimulus alpha rhythms are related to conscious visual perception: a high-resolution EEG study. Cereb Cortex
, 2006
"... Conscious and unconscious visuospatial processes have been related to parietooccipital cortical activation as revealed by late visual-evoked potentials. Here the working hypothesis was that a specific pattern of pre- and poststimulus theta (about 4--6 Hz) and alpha (about 6--12 Hz) rhythms is differ ..."

Cortisol effects on averaged evoked potentials, alpha-rhythm, time estimation, and two-flash fusion threshold
- Psychosomatic Medicine
, 1970
"... Eighteen normal male subjects, each serving as his own control, were tested with acute cortisol and placebo intravenous infusions on separate days. Previous studies have shown that enhancement of the amplitude of the averaged-evoked-potential by random flashes reflects selective attention. Cortisol ..."
