Properties of beta oscillations in Dup15q syndrome [PDF]

Journal of Neurodevelopmental Disorders, 2020
AbstractBackgroundDuplications of 15q11.2-q13.1 (Dup15q syndrome) are highly penetrant for autism, intellectual disability, hypotonia, and epilepsy. The 15q region harbors genes critical for brain development, particularlyUBE3Aand a cluster of gamma-aminobutyric acid type A receptor (GABAAR) genes.

Case Report: Chronic Adaptive Deep Brain Stimulation Personalizing Therapy Based on Parkinsonian State

Frontiers in Human Neuroscience, 2021
We describe the case of a 51-year-old man with Parkinson's disease (PD) presenting with motor fluctuations, who received bilateral subthalamic deep brain stimulation (DBS) with an adaptive DBS (aDBS) device, Percept™ PC (Medtronic, Inc. , Minneapolis, MN)

Efficient suppression of parkinsonian beta oscillations in a closed-loop model of deep brain stimulation with amplitude modulation

Frontiers in Human Neuroscience, 2023
IntroductionParkinson's disease (PD) is a movement disorder characterized by the pathological beta band (15–30 Hz) neural oscillations within the basal ganglia (BG).

Characterizing cortical responses to short-term multidisciplinary intensive rehabilitation treatment in patients with Parkinson’s disease: A transcranial magnetic stimulation and electroencephalography study

Frontiers in Aging Neuroscience, 2022
Combined transcranial magnetic stimulation and electroencephalography (TMS-EEG) is a powerful non-invasive tool for qualifying the neurophysiological effects of interventions by recording TMS-induced cortical activation with high temporal resolution and ...

Dual-task walking improvement with enhanced kinesthetic awareness in Parkinson’s disease with mild gait impairment: EEG connectivity and clinical implication

Frontiers in Aging Neuroscience, 2022
Due to basal ganglia dysfunction, short step length is a common gait impairment in Parkinson’s disease (PD), especially in a dual-task walking. Here, we use electroencephalography (EEG) functional connectivity to investigate neural mechanisms of a stride

The Role of Beta Oscillations in Mental Time Travel

Psychological Science, 2023
The brain processes short-interval timing but also allows people to project themselves into the past and the future (i.e., mental time travel [MTT]). Beta oscillations index seconds-long-interval timing (i.e., higher beta power is associated with longer durations).

Profiling the low-beta characteristics of the subthalamic nucleus in early- and late-onset Parkinson’s disease

Frontiers in Aging Neuroscience, 2023
ObjectivesLow-beta oscillation (13–20 Hz) has rarely been studied in patients with early-onset Parkinson’s disease (EOPD, age of onset ≤50 years).

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 ...

Investigating the role of islet cytoarchitecture in its oscillation using a new beta-cell cluster model. [PDF]

PLoS ONE, 2007
The oscillatory insulin release is fundamental to normal glycemic control. The basis of the oscillation is the intercellular coupling and bursting synchronization of beta cells in each islet.

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
