Reduced Modulation of Theta and Beta Oscillations Mediates Empathy Impairment in Parkinson's Disease [PDF]

Brain and Behavior
Background Empathy is an inaccessible part of advanced social cognitive functions in humans. Impairment of empathy greatly affects the quality of life of patients with Parkinson's disease (PD) but the underlying neurophysiologic mechanisms have not been ...

Beta Oscillations, Timing and Stuttering

Frontiers 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 ...

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.

Amplitude and frequency modulation of subthalamic beta oscillations jointly encode the dopaminergic state in Parkinson's disease. [PDF]

NPJ Parkinsons Dis, 2022
Brain states in health and disease are classically defined by the power or the spontaneous amplitude modulation (AM) of neuronal oscillations in specific frequency bands.

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

Frontiers 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.

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 ...

Beta Peak Frequencies at Rest Correlate with Endogenous GABA+/Cr Concentrations in Sensorimotor Cortex Areas. [PDF]

PLoS ONE, 2016
Neuronal oscillatory activity in the beta band (15-30 Hz) is a prominent signal within the human sensorimotor cortex. Computational modeling and pharmacological modulation studies suggest an influence of GABAergic interneurons on the generation of beta ...

Spontaneous neuronal oscillations in the human insula are hierarchically organized traveling waves

eLife, 2022
The insula plays a fundamental role in a wide range of adaptive human behaviors, but its electrophysiological dynamics are poorly understood. Here, we used human intracranial electroencephalographic recordings to investigate the electrophysiological ...

Low-frequency deep brain stimulation reveals resonant beta-band evoked oscillations in the pallidum of Parkinson’s Disease patients

Frontiers in Human Neuroscience, 2023
IntroductionEvidence suggests that spontaneous beta band (11–35 Hz) oscillations in the basal ganglia thalamocortical (BGTC) circuit are linked to Parkinson’s disease (PD) pathophysiology.
