Neutrino oscillations and neutrinoless double beta decay [PDF]

Physical Review D, 2001
The relation between neutrino oscillation parameters and neutrinoless double beta decay is studied, assuming normal and inverse hierarchies for Majorana neutrino masses. For normal hierarchy the crucial dependence on U_{e3} is explored. The link with tritium beta decay is also briefly discussed.

Beta oscillations in the parkinsonian primate: Similar oscillations across different populations

Neurobiology of Disease, 2016
Parkinson's disease (PD) is characterized by excessive beta band oscillations (BBO) in neuronal spiking activity across basal ganglia (BG) nuclei. High frequency stimulation of the subthalamic nucleus, an effective treatment for PD, suppresses these oscillations.

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?

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.

Language–motor interference reflected in MEG beta oscillations

NeuroImage, 2015
The involvement of the brain's motor system in action-related language processing can lead to overt interference with simultaneous action execution. The aim of the current study was to find evidence for this behavioural interference effect and to investigate its neurophysiological correlates using oscillatory MEG analysis. Subjects performed a semantic

Alternating Modulation of Subthalamic Nucleus Beta Oscillations during Stepping [PDF]

The Journal of Neuroscience, 2018
Gait disturbances in Parkinson's disease are commonly refractory to current treatment options and majorly impair patient's quality of life. Auditory cues facilitate gait and prevent motor blocks. We investigated how neural dynamics in the human subthalamic nucleus of Parkinsons's disease patients (14 male, 2 female) vary during stepping and whether ...

The role of cortical beta oscillations in time estimation [PDF]

Human Brain Mapping, 2016
AbstractEstimation of time is central to perception, action, and cognition. Human functional magnetic resonance imaging (fMRI) and positron emission topography (PET) have revealed a positive correlation between the estimation of multi‐second temporal durations and neuronal activity in a circuit of sensory and motor areas, prefrontal and temporal ...

Alterations in Brain Connectivity Underlying Beta Oscillations in Parkinsonism

PLoS Computational Biology, 2011
Cortico-basal ganglia-thalamocortical circuits are severely disrupted by the dopamine depletion of Parkinson's disease (PD), leading to pathologically exaggerated beta oscillations. Abnormal rhythms, found in several circuit nodes are correlated with movement impairments but their neural basis remains unclear.

Pain-Related Suppression of Beta Oscillations Facilitates Voluntary Movement [PDF]

Cerebral Cortex, 2016
Increased beta oscillations over sensorimotor cortex are antikinetic. Motor- and pain-related processes separately suppress beta oscillations over sensorimotor cortex leading to the prediction that ongoing pain should facilitate movement. In the current study, we used a paradigm in which voluntary movements were executed during an ongoing pain ...
