Alpha Oscillations and Early Stages of Visual Encoding [PDF]
Frontiers in Psychology, 2011 For a long time alpha oscillations have been functionally linked to the processing of visual information. Here we propose an new theory about the functional meaning of alpha. The central idea is that synchronized alpha reflects a basic processing mode that controls access to information stored in a complex long-term memory system, which we term ...

Frontiers in Psychiatry, 2020 Despite growing evidence of aberrant neuronal complexity in Alzheimer’s disease (AD), it remains unclear how this variation arises. Neural oscillations reportedly comprise different functions depending on their own properties.

Parametric resonance for antineutrino conversions using LSND best-fit results with a 3+1 flavor scheme [PDF]
, 2006 An analytical solution to a parametric resonance effect for antineutrinos in a 3+1 flavor (active+sterile) scheme using multiple non-adiabatic density shifts is presented.

Functional aspects of alpha oscillations in the EEG
International Journal of Psychophysiology, 2001 Experimental evidence suggests a functional significance of EEG alpha rhythms. Event-related, evoked, and induced alpha rhythms may have functional correlates in primary sensory processing and preparatory processes. These results are in accordance with the view that spontaneous and induced EEG alpha rhythms have quasi-deterministic properties.

The role of alpha oscillations for illusory perception
Behavioural Brain Research, 2014 Alpha oscillations are a prominent electrophysiological signal measured across a wide range of species and cortical and subcortical sites. Alpha oscillations have been viewed for a long time as an "idling" rhythm, purely reflecting inactive sites.

Alpha oscillations and the control of voluntary saccadic behavior [PDF]
Experimental Brain Research, 2012 The purpose of this review is to explore the dynamic properties of alpha oscillations as biological covariates of intra- and inter-individual variance in saccadic behavior. A preponderance of research suggests that oscillatory dynamics in the alpha band co-vary with performance on a number of visuo-spatial cognitive tasks.

Indirect Measurement of the Vertex and Angles of the Unitarity Triangle [PDF]
, 1998 The precise measurements of the Bd oscillation frequency and the limit on the Bs one one as well as the determination of the Cabibbo-Kobayashi-Maskawa matrix element Vub improve the constraints on the other elements of this matrix.

Illusory Jitter Perceived at the Frequency of Alpha Oscillations [PDF]
Current Biology, 2017 Neural oscillations, such as alpha (8-13 Hz), beta (13-30 Hz), and gamma (30-100 Hz), are widespread across cortical areas, and their possible functional roles include feature binding [1], neuronal communication [2, 3], and memory [1, 4]. The most prominent signal among these neural oscillations is the alpha oscillation.

Repetitive Passive Finger Movement Modulates Primary Somatosensory Cortex Excitability
Frontiers in Human Neuroscience, 2018 Somatosensory inputs induced by repetitive passive movement (RPM) modulate primary motor cortex (M1) excitability; however, it is unclear whether RPM affects primary somatosensory cortex (S1) excitability.
