Beta oscillations and urinary voiding in Parkinson disease [PDF]

open access: yesNeurology, 2018
ObjectivesTo investigate the role of beta oscillations in urinary voiding and their association with lower urinary tract symptoms in Parkinson disease (PD).MethodsWe used surgically implanted deep brain stimulation electrodes to record local field potential signals from the subthalamic nucleus (STN) and globus pallidus interna (GPi) of patients with PD

A New Framework to Explain Sensorimotor Beta Oscillations [PDF]

open access: yesTrends in Cognitive Sciences, 2016
Oscillatory activity in the beta frequency range from sensorimotor cortices is modulated by movement; however, the functional role of this activity remains unknown. In a recent study, Tan et al. tested a novel hypothesis that beta power reflects estimates of uncertainty in parameters of motor forward models.

Non-linear Relationship between BOLD Activation and Amplitude of Beta Oscillations in the Supplementary Motor Area during Rhythmic Finger Tapping and Internal Timing

open access: yesFrontiers in Human Neuroscience, 2017
Functional imaging studies using BOLD contrasts have consistently reported activation of the supplementary motor area (SMA) both during motor and internal timing tasks.

Individual differences in beta-band oscillations predict motor-inhibitory control

open access: yesFrontiers in Neuroscience, 2023
ObjectiveThe ability of motor-inhibitory control is critical in daily life. The physiological mechanisms underlying motor inhibitory control deficits remain to be elucidated.

Parkinsonian beta oscillations in the external globus pallidus and their relationship with subthalamic nucleus activity [PDF]

open access: yes, 2008
Inappropriately synchronized beta (β) oscillations (15–30 Hz) in the subthalamic nucleus (STN) accompany movement difficulties in idiopathic Parkinson's disease (PD).

Causal evidence that intrinsic beta frequency is relevant for enhanced signal propagation in the motor system as shown through rhythmic TMS [PDF]

open access: yes, 2016
Correlative evidence provides support for the idea that brain oscillations underpin neural computations. Recent work using rhythmic stimulation techniques in humans provide causal evidence but the interactions of these external signals with intrinsic ...

Slow oscillations persist in pancreatic beta cells lacking phosphofructokinase M [PDF]

open access: yes, 2022
Pulsatile insulin secretion by pancreatic beta cells is necessary for tight glucose control in the body. Glycolytic oscillations have been proposed as the mechanism for generating the electrical oscillations underlying pulsatile insulin secretion.

Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

open access: yeseLife, 2017
Motor cortical beta oscillations have been reported for decades, yet their behavioral correlates remain unresolved. Some studies link beta oscillations to changes in underlying neural activity, but the specific behavioral manifestations of these reported

Balance between pallidal neural oscillations correlated with dystonic activity and severity

open access: yesNeurobiology of Disease, 2023
Background and objective: The balance between neural oscillations provides valuable insights into the organisation of neural oscillations related to brain states, which may play important roles in dystonia.
