Emergence of Beta Oscillations of a Resonance Model for Parkinson’s Disease [PDF]

open access: yesNeural Plasticity, 2020
In Parkinson’s disease, the excess of beta oscillations in cortical-basal ganglia (BG) circuits has been correlated with normal movement suppression. In this paper, a physiologically based resonance model, generalizing an earlier model of the STN-GPe circuit, is employed to analyze critical dynamics of the occurrence of beta oscillations, which ...

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

Beta band oscillations in the motor thalamus are modulated by visuomotor coordination in essential tremor patients

open access: yesFrontiers in Human Neuroscience, 2023
IntroductionBeta oscillations in sensorimotor structures contribute to the planning, sequencing, and stopping of movements, functions that are typically associated with the role of the basal ganglia.

Beta oscillations in face recognition

open access: yesInternational Journal of Psychophysiology, 2005
This report presents an analysis of the brain's beta oscillations in face recognition. We performed experiments on 26 subjects with a strategy consisting of two types of stimulations: (1) the picture of an elder anonymous lady (unknown face) and (2) the picture of the subject's own grandmother (known face).

Beta oscillations, timing, and stuttering

open access: yesFrontiers in Human Neuroscience, 2015
It has been proposed that one of the causes of stuttering is a deficit in brain timing networks (Alm, 2004; Ludlow and Loucks, 2004; Etchell et al., 2014). In stuttering, there appear to be structural and functional abnormalities in brain areas (such as the basal ganglia and supplementary motor area) that provide the substrate for internal timing (the ...

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.

I: Retrieval of Atmospheric Carbon Dioxide from High-Resolution Spectra. II: Interannual Variability of the Stratospheric Quasi-Biennual Oscillation [PDF]

open access: yes, 2011
This thesis is devoted to an understanding of climate changes in the troposphere and the stratosphere from different aspects. In the troposphere, projecting future climate depends on our understanding of the exchange of CO₂ between the atmosphere, oceans,

Movement-Related Activity of Human Subthalamic Neurons during a Reach-to-Grasp Task

open access: yesFrontiers in Human Neuroscience, 2017
The aim of the study was to record movement-related single unit activity (SUA) in the human subthalamic nucleus (STN) during a standardized motor task of the upper limb.
