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 ...

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 ...

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 ...

Frequency Characteristics of Rhythm Non-Assimilation in Canine Ventricular Fibrillation [PDF]
Общая реаниматология, 2010 Ventricular fibrillation is the main cause of sudden cardiac death in many countries, including Russia; therefore to study ventricular fibrillation is an urgent problem.

Heart Rate and Rhythm and the Benefit of Beta-Blockers in Patients With Heart Failure [PDF]
Journal of the American College of Cardiology, 2017 The relationship between mortality and heart rate remains unclear for patients with heart failure with reduced ejection fraction in either sinus rhythm or atrial fibrillation (AF).This analysis explored the prognostic importance of heart rate in patients with heart failure with reduced ejection fraction in randomized controlled trials comparing beta ...

Beta rhythm modulation by speech sounds: somatotopic mapping in somatosensory cortex. [PDF]
Sci Rep, 2016 AbstractDuring speech listening motor regions are somatotopically activated, resembling the activity that subtends actual speech production, suggesting that motor commands can be retrieved from sensory inputs. Crucially, the efficient motor control of the articulators relies on the accurate anticipation of the somatosensory reafference.

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 ...

Beta rhythm modulation in the evaluation of cortical sensorimotor function [PDF]
, 2023 The cortical ~20-Hz beta rhythm that arises mainly from the primary sensorimotor (SM1) cortex reacts to voluntary movements or motor imagery as well as to somatosensory stimuli. The decrease in beta power shortly after somatosensory stimulus or movement is called beta suppression, and the subsequent increase in beta power is called beta rebound.

Effects of Motor Imagery Tasks on Brain Functional Networks Based on EEG Mu/Beta Rhythm. [PDF]
Brain Sci, 2022 Motor imagery (MI) refers to the mental rehearsal of movement in the absence of overt motor action, which can activate or inhibit cortical excitability.

High beta rhythm amplitude in olfactory learning signs a well-consolidated and non-flexible behavioral state. [PDF]
Sci Rep, 2019 International audienceBeta rhythm (15-30 Hz) is a major candidate underlying long-range communication in the brain. In olfactory tasks, beta activity is strongly modulated by learning but its condition of expression and the network(s) responsible for its
