Infra‐slow modulation of fast beta/gamma oscillations in the mouse visual system [PDF]

, 2021
Infra‐slow (<0.02 Hz) and fast beta/gamma (20–100 Hz) oscillations in neurophysiological activity have been widely found in the subcortical visual system. While it is well established that fast beta/gamma oscillations are involved in visual processing,

Differential modulation of sensorimotor beta oscillations by beta tACS alone and combined repetitive paired-pulse TMS with tACS

NeuroImage
Background: Combined stimulation with transcranial alternating current stimulation (tACS) at the beta frequency and repetitive paired-pulse transcranial magnetic stimulation (rPPS) produces different after-effects on cortical excitability in the primary ...

Complex Interaction Between Low-Frequency APD Oscillations and Beat-to-Beat APD Variability in Humans Is Governed by the Sympathetic Nervous System

Frontiers in Physiology, 2020
BackgroundRecent clinical, experimental and modeling studies link oscillations of ventricular repolarization in the low frequency (LF) (approx. 0.1 Hz) to arrhythmogenesis.

The relationship between membrane potential and calcium dynamics in glucose-stimulated beta cell syncytium in acute mouse pancreas tissue slices. [PDF]

PLoS ONE, 2013
Oscillatory electrical activity is regarded as a hallmark of the pancreatic beta cell glucose-dependent excitability pattern. Electrophysiologically recorded membrane potential oscillations in beta cells are associated with in-phase oscillatory cytosolic

Basal ganglia, beta oscillations, and insomnia [PDF]

Science, 2020
Neuroscience Insomnia affects up to 60% of Parkinson's disease patients. Beta oscillations are especially prominent in the basal ganglia in idiopathic Parkinson's disease. Mizrahi-Kliger et al. hypothesized that basal ganglia pathophysiology may not only play a mediating role in Parkinson's motor symptoms but may also contribute to Parkinson's insomnia.

Unpredicted pitch modulates beta oscillatory power during rhythmic entrainment to a tone sequence

Frontiers in Psychology, 2016
Extracting temporal regularities in external stimuli in order to predict upcoming events is an essential aspect of perception. Fluctuations in induced power of beta band (15 – 25 Hz) oscillations in auditory cortex are involved in predictive timing ...

Subthalamic beta oscillations correlate with dopaminergic degeneration in experimental Parkinsonism

, 2021
Excessive beta activity has been shown in local field potential recordings from the cortico-basal ganglia loop of Parkinson's disease patients and in its various animal models.

Excitatory deep brain stimulation quenches beta oscillations arising in a computational model of the subthalamo-pallidal loop

Scientific Reports, 2022
Parkinson’s disease (PD) is associated with abnormal $$\beta$$ β band oscillations (13–30 Hz) in the cortico-basal ganglia circuits. Abnormally increased striato-pallidal inhibition and strengthening the synaptic coupling between subthalamic nucleus (STN)
