Synthetic hydrogen spectra of prominence oscillations

, 2014
Context. Prominence oscillations have been mostly detected using Doppler velocity, although there are also claimed detections by means of periodic variations in half-width or line intensity.

In silico model of basal ganglia deep brain stimulation in Parkinson's disease captures range of effective parameters for pathological beta power suppression.

PLoS Computational Biology
In Parkinson's disease (PD), the beta band (12-30 Hz) component of basal ganglia activity is pathologically high. Deep brain stimulation (DBS) is an effective treatment to suppress symptoms of PD and is known to suppress pathological beta activity ...

Correlation between cortical beta power and gait speed is suppressed in a parkinsonian model, but restored by therapeutic deep brain stimulation

Neurobiology of Disease, 2018
The motor cortex and subthalamic nucleus (STN) of patients with Parkinson's disease (PD) exhibit abnormally high levels of electrophysiological oscillations in the ~12–35 Hz beta-frequency range.

The amplitude of solar oscillations using stellar techniques

, 2008
The amplitudes of solar-like oscillations depend on the excitation and damping, both of which are controlled by convection. Comparing observations with theory should therefore improve our understanding of the underlying physics.

Deep brain stimulation modulates pallidal and subthalamic neural oscillations in Tourette's syndrome

Brain and Behavior, 2019
Introduction Previous studies found subthalamic nucleus deep brain stimulation (STN‐DBS) has clinical effect on Parkinson's disease, dystonia, and obsessive compulsive disorder.

Children with cerebral palsy have altered oscillatory activity in the motor and visual cortices during a knee motor task

NeuroImage: Clinical, 2017
The neuroimaging literature on cerebral palsy (CP) has predominantly focused on identifying structural aberrations within the white matter (e.g., fiber track integrity), with very few studies examining neural activity within the key networks that serve ...

Does suppression of oscillatory synchronisation mediate some of the therapeutic effects of DBS in patients with Parkinson’s disease?

Frontiers in Integrative Neuroscience, 2012
There is growing evidence for exaggerated oscillatory neuronal synchronisation in patients with Parkinson’s disease. In particular, oscillations at around 20 Hz, in the so-called beta frequency band, relate to the cardinal symptoms of bradykinesia and ...

Two particle states, lepton mixing and oscillations [PDF]

, 2000
Discussions of lepton mixing and oscillations consider generally only flavor oscillations of neutrinos and neglect the accompanying charged leptons. In cases of experimental interest like pion or nuclear beta decay an oscillation pattern is expected ...

Beta bursts in the parkinsonian cortico-basal ganglia network form spatially discrete ensembles

Neurobiology of Disease
Defining spatial synchronisation of pathological beta oscillations is important, given that many theories linking them to parkinsonian symptoms propose a reduction in the dimensionality of the coding space within and/or across cortico-basal ganglia ...
