Response preparation and inhibition: The role of the cortical sensorimotor beta rhythm [PDF]
Neuroscience, 2008 Paradigms requiring either a GO or a NO-GO response are often used to study the neural mechanisms of response inhibition. Here this issue is examined from the perspective of event-related beta (14-30 Hz) oscillatory activity.

Beta rhythm modulation in the evaluation of cortical sensorimotor function
, 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.

Beta‐blocker use and mortality among patients with systolic heart failure and pacemaker rhythm
ESC Heart Failure, 2023 Aims Beta‐blockers are proven to improve survival among patients with heart failure with reduced ejection fraction. Their efficacy in patients with heart failure with reduced ejection fraction and pacemaker devices has not been demonstrated.

eLife, 2023 Even during sustained attention, enhanced processing of attended stimuli waxes and wanes rhythmically, with periods of enhanced and relatively diminished visual processing (and subsequent target detection) alternating at 4 or 8 Hz in a sustained visual ...

Grasping the semantic of actions: a combined behavioral and MEG study
Frontiers in Human Neuroscience, 2022 There is experimental evidence that the brain systems involved in action execution also play a role in action observation and understanding. Recently, it has been suggested that the sensorimotor system is also involved in language processing.

NeuroImage, 2022 We aimed to test the idea that rhythmic transcranial magnetic stimulation (TMS) entrains cortical oscillations. To do this, we examined oscillatory responses in the electroencephalogram (EEG) to TMS over primary motor cortex. In particular, we contrasted

Brain Stimulation, 2022 Background: Neural oscillations in the primary motor cortex (M1) shape corticospinal excitability. Power and phase of ongoing mu (8–13 Hz) and beta (14–30 Hz) activity may mediate motor cortical output.

Dopaminergic drugs alter beta coherence during motor imagery and motor execution in healthy adults [PDF]
Arquivos de Neuro-Psiquiatria, 2020 Background: Motor Imagery (MI) represents the cognitive component of the movement and recruits dopaminergic systems. Objective: To investigate the role of dopaminergic system through the action of methylphenidate and risperidone over beta coherence ...

Cortical processing during robot and functional electrical stimulation
Frontiers in Systems Neuroscience, 2023 IntroductionLike alpha rhythm, the somatosensory mu rhythm is suppressed in the presence of somatosensory inputs by implying cortical excitation. Sensorimotor rhythm (SMR) can be classified into two oscillatory frequency components: mu rhythm (8–13 Hz ...
