Beta oscillations and urinary voiding in Parkinson disease [PDF]

Neurology, 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

Attention modulates beta oscillations during prolonged tactile stimulation [PDF]

European Journal of Neuroscience, 2010
AbstractThe inter‐play between changes in beta‐band (14–30‐Hz) cortical rhythms and attention during somatosensation informs us about where and when relevant processes occur in the brain. As such, we investigated the effects of attention on somatosensory evoked and induced responses using vibrotactile stimulation and magnetoencephalographic recording ...

Beta oscillations reflect supramodal information during perceptual judgment [PDF]

Proceedings of the National Academy of Sciences, 2017
SignificanceWhen a perceptual judgment has to be made comparing inputs from different sensory modalities (here, tactile and auditory), the relevant information needs to be coded in a supramodal way. We studied the role of beta oscillations in the premotor system, which had previously been linked to tactile working memory and decision making.

Beta-Band Resonance and Intrinsic Oscillations in a Biophysically Detailed Model of the Subthalamic Nucleus-Globus Pallidus Network

Frontiers in Computational Neuroscience, 2019
Increased beta-band oscillatory activity in the basal ganglia network is associated with Parkinsonian motor symptoms and is suppressed with medication and deep brain stimulation (DBS).

The lifespan trajectory of neural oscillatory activity in the motor system

Developmental Cognitive Neuroscience, 2018
Numerous studies connect beta oscillations in the motor cortices to volitional movement, and beta is known to be aberrant in multiple movement disorders.

Parietal tACS at beta frequency improves vision in a crowding regime

NeuroImage, 2020
Visual crowding is the inability to discriminate objects when presented with nearby flankers and sets a fundamental limit for conscious perception.

Predictions on the neutrinoless double beta decay from the leptogenesis via the LHu flat direction [PDF]

, 2002
If the baryon asymmetry in the present universe is generated by decays of the $L H_u$ flat direction, the observed baryon asymmetry requires the mass of the lightest neutrino to be much smaller than the mass scale indicated from the atmospheric and solar

Delta–Beta Coupled Oscillations Underlie Temporal Prediction Accuracy [PDF]

Cerebral Cortex, 2014
The ability to generate temporal predictions is fundamental for adaptive behavior. Precise timing at the time-scale of seconds is critical, for instance to predict trajectories or to select relevant information. What mechanisms form the basis for such accurate timing?

Dynamical Analyses on Beta Oscillations in a STN-GPE-GPI Model of Parkinson’s Disease

Complexity, 2020
Exploring the behaviors of beta oscillations in the basal ganglia is helpful to understand the mechanism of Parkinson’s disease. Studies have shown that the external and internal segments (GPe, GPi) of the globus pallidus receive different intensities of

A New Framework to Explain Sensorimotor Beta Oscillations [PDF]

Trends 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.
