Motor-Related Mu/Beta Rhythm in Older Adults: A Comprehensive Review [PDF]
Brain Sciences, 2023 Mu rhythm, also known as the mu wave, occurs on sensorimotor cortex activity at rest, and the frequency range is defined as 8–13Hz, the same frequency as the alpha band.

Reproducibility of Rolandic beta rhythm modulation in MEG and EEG.
J Neurophysiol, 2022 The present study demonstrates that beta rhythm modulation is highly reproducible in a group of healthy subjects within a year. Hence, it can be reliably used as a biomarker in longitudinal follow-up studies in different neurological patient groups to reflect changes in the functional state of the sensorimotor cortex.

The effect of alertness and attention on the modulation of the beta rhythm to tactile stimulation [PDF]
Physiological Reports, 2021 Beta rhythm modulation has been used as a biomarker to reflect the functional state of the sensorimotor cortex in both healthy subjects and patients. Here, the effect of reduced alertness and active attention to the stimulus on beta rhythm modulation was investigated.

Period concatenation underlies interactions between gamma and beta rhythms in neocortex [PDF]
Frontiers in Cellular Neuroscience, 2008 The neocortex generates rhythmic electrical activity over a frequency range covering many decades. Specific cognitive and motor states are associated with oscillations in discrete frequency bands within this range, but it is not known whether ...

A modelling study of beta-amyloid induced change in hippocampal theta rhythm [PDF]
, 2011 Many dementia cases, such as Alzheimer’s disease (AD), are characterized by an increase in low frequency field potential oscillations. However, a definitive understanding of the effects of the beta-Amyloid peptide, which is a main marker of AD, on

Beta rhythm events predict corticospinal motor output. [PDF]
Sci Rep, 2019 Abstract The beta rhythm (15-30 Hz) is a prominent signal of sensorimotor cortical activity. This rhythm is not sustained but occurs non-rhythmically as brief events of a few (1–2) oscillatory cycles. Recent work on the relationship between these events and sensorimotor performance suggests that they are the biologically relevant ...

Model neocortical microcircuit supports beta and gamma rhythms
2021 10th International IEEE/EMBS Conference on Neural Engineering (NER), 2021 Gamma and beta rhythms in neocortical circuits are thought to be caused by distinct subcircuits involving different type of interneurons. However, it is not clear how these distinct but inter-linked intrinsic circuits interact with afferent drive to engender the two rhythms. We report a biophysical computational model to investigate the hypothesis that

Neurofeedback training for children with ADHD using individual beta rhythm. [PDF]
Cogn Neurodyn, 2022 Neurofeedback training (NFT) is a noninvasive neuromodulation method for children with attention-deficit/hyperactivity disorder (ADHD). Brain rhythms, the unique pattern in electroencephalogram (EEG), are widely used as the training target. Most of current studies used a fixed frequency division of brain rhythms, which ignores the individual ...

Perception of pro- and antisocial behavior by children: modulations of EEG alpha and beta rhythms [PDF]
SHS Web of Conferences, 2019 The paper surveys the behavior and psychophysiological responses (electroencephalographic power modulations of the alpha and beta rhythms) in 16 boys and 33 girls aged from 1.5 to 3.5 years when they were distributing reward tokens (carton cookies) among

A mean field model for movement induced changes in the beta rhythm. [PDF]
J Comput Neurosci, 2017 In electrophysiological recordings of the brain, the transition from high amplitude to low amplitude signals are most likely caused by a change in the synchrony of underlying neuronal population firing patterns. Classic examples of such modulations are the strong stimulus-related oscillatory phenomena known as the movement related beta decrease (MRBD ...
