Can the Spontaneous Electroencephalography Theta/Beta Power Ratio and Alpha Oscillation Measure Individuals’ Attentional Control?

open access: yesBehavioral Sciences
Past studies have shown that spontaneous electroencephalography indicators—namely, the theta/beta power ratio and alpha oscillation—may measure individuals’ attentional control processes.

Striatal Beta Oscillation and Neuronal Activity in the Primate Caudate Nucleus Differentially Represent Valence and Arousal Under Approach-Avoidance Conflict [PDF]

open access: yesFrontiers in Neuroscience, 2020
An approach-avoidance (Ap–Av) conflict arises when an individual has to decide whether to accept or reject a compound offer that has features indicating both reward and punishment.

Two distinct olfactory bulb sublaminar networks involved in gamma and beta oscillation generation: a CSD study in the anesthetized rat.

open access: yesFrontiers in Neural Circuits, 2014
A prominent feature of olfactory bulb (OB) dynamics is the expression of characteristic local field potential (LFP) rhythms, including a slow respiration-related rhythm and two fast alternating oscillatory rhythms, beta (15-30 Hz) and gamma (40-90 Hz ...

The beta oscillation conditions in a simplified basal ganglia network. [PDF]

open access: yesCogn Neurodyn, 2019
Parkinson's disease is a type of motor dysfunction disease that is induced mainly by abnormal interactions between the subthalamic nucleus (STN) and globus pallidus (GP) neurons. Periodic oscillatory activities with frequencies of 13-30 Hz are the main physiological characteristics of Parkinson's disease.

Pure phase-locking of beta/gamma oscillation contributes to the N30 frontal component of somatosensory evoked potentials [PDF]

open access: yesBMC Neuroscience, 2007
Background Evoked potentials have been proposed to result from phase-locking of electroencephalographic (EEG) activities within specific frequency bands.

On the oscillation of impulsively damped halflinear oscillators [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2000
The authors consider the nonlinear impulsive system $$(\phi_\beta(x'))' + \phi_\beta (x) = 0 \quad (t \neq t_n), \quad x'(t_n + 0) = b_n x' (t_n)$$ where $n = 1, 2 \dots $, $\phi_\beta(u)=|u|^\beta\operatorname{sgn} u$ with $\beta>0$, and $0\le b_n \le 1$

Increased beta-HFO phase-amplitude coupling in the subthalamic nucleus during movement in Parkinson's disease [PDF]

open access: yesNeuroImage: Reports
In Parkinson's disease (PD), increased amplitude of high-frequency oscillations (HFO) has been confirmed to be coupled with the beta oscillations phase, resulting in increased phase-amplitude coupling (PAC) in the subthalamic nucleus (STN).

Understanding the Role of Sensorimotor Beta Oscillations [PDF]

open access: yesFrontiers in Systems Neuroscience, 2021
Beta oscillations have been predominantly observed in sensorimotor cortices and basal ganglia structures and they are thought to be involved in somatosensory processing and motor control. Although beta activity is a distinct feature of healthy and pathological sensorimotor processing, the role of this rhythm is still under debate. Here we review recent
