Dynamic Neural State Identification in Deep Brain Local Field Potentials of Neuropathic Pain

Frontiers in Neuroscience, 2018
In neuropathic pain, the neurophysiological and neuropathological function of the ventro-posterolateral nucleus of the thalamus (VPL) and the periventricular gray/periaqueductal gray area (PVAG) involves multiple frequency oscillations.

Individual differences in alpha frequency drive crossmodal illusory perception [PDF]

, 2014
Perception routinely integrates inputs from different senses. Stimulus temporal proximity critically determines whether or not these inputs are bound together.

First Simultaneous Observation of H-alpha Moreton Wave, EUV Wave, and Filament/Prominence Oscillations [PDF]

, 2011
We report on the first simultaneous observation of an H-alpha Moreton wave, the corresponding EUV fast coronal waves, and a slow and bright EUV wave (typical EIT wave).

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.

Low-frequency oscillatory correlates of auditory predictive processing in cortical-subcortical networks: a MEG-study [PDF]

, 2018
Emerging evidence supports the role of neural oscillations as a mechanism for predictive information processing across large-scale networks. However, the oscillatory signatures underlying auditory mismatch detection and information flow between brain ...

Alpha oscillations modulate premotor-cerebellar connectivity in motor learning: Insights from transcranial alternating current stimulation

NeuroImage, 2021
Alpha oscillations (8-13 Hz) have been suggested to play an important role in dynamic neural processes underlying learning and memory. The goal of this study was to scrutinize the role of alpha oscillations in communication within a cortico-cerebellar ...

Magnetic quantum oscillations in the charge-density-wave state of the organic metals $\alpha $-(BEDT-TTF)$_2$MHg(SCN)$_4$ with M = K and Tl

, 2013
The low-temperature charge-density-wave (CDW) state in the layered organic metals $\alpha $-(BEDT-TTF)$_2$MHg(SCN)$_4$ has been studied by means of the Shubnikov -- de Haas and de Haas -- van Alphen effects.

Bias driven coherent carrier dynamics in a two-dimensional aperiodic potential [PDF]

, 2008
We study the dynamics of an electron wave-packet in a two-dimensional square lattice with an aperiodic site potential in the presence of an external uniform electric field. The aperiodicity is described by $\epsilon_{\bf m} = V\cos{(\pi\alpha m_x^{\nu_x})

Observation of multiple sausage oscillations in cool postflare loop

, 2008
Using simultaneous high spatial (1.3 arc sec) and temporal (5 and 10 s) resolution H-alpha observations from the 15 cm Solar Tower Telescope at ARIES, we study the oscillations in the relative intensity to explore the possibility of sausage oscillations ...

Alpha oscillations in brain functioning: an integrative theory

International Journal of Psychophysiology, 1997
The old concept stating that EEG alpha (10-Hz) activity reflects passive or idling states of the brain is giving way to modern views of 10-Hz oscillations in relation to diverse brain functions comprising sensory, motor, and memory processes: (1) Spontaneous alpha activity is not pure noise as shown by methods of chaos analysis.
