The sensorimotor mu rhythm, also known as mu wave, comb or wicket rhythms or arciform rhythms, are synchronized patterns of electrical activity involving large numbers of neurons, probably of the pyramidal type, in the part of the brain that controls voluntary movement. [1]

Mu appears as arch-like alpha activity (usually 7-11 Hz) over the parasagittal regions; it can be bilateral but is often predominant on one side or the other. Particularly in cases of breach rhythm, it can appear rather high amplitude and sharp, but should not be mistaken for epileptiform activity.

Indeed, while many mu suppression experiments define mu as alpha-band (8–13 Hz) activity, mu waves are actually considered to be composed of contributions from two frequencies, including alpha and beta (13–30 Hz), and have characteristic peaks at …

Feb 16, 2009 · It has a range between 8 and 13 Hz and partially overlaps with other type of brain waves. It reflects the synchronous firing of motor neurons in rest state. Fig. 1.9 shows a sample mu wave.

Mu waves are in the range of 8-13 Hz and arise from large groups of neurons in the brain. Recently Mu brain waves have been associated with the “mirror neuron” system that activates when we watch another person’s activity.

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. Mu rhythm is a cortical oscillation that can be recorded from the scalp over ...

On the EEG task, both groups demonstrated significant attenuation of the mu rhythm when executing an action. However, when observing movement, the individuals with ASD showed significantly reduced attenuation of the mu wave. Behaviorally assessed imitation skills were correlated with degree of mu wave attenuation during observation of movement.

Apr 18, 2016 · As it says, Mu Waves are a type of oscillating electrical rhythm within the brain that can be seen in an EEG recording. In particular, they occur in the sensorimotor cortex, which is the area of the brain associated with coordinating muscle motion and the perception of one’s muscle and joint muscle.

The sensorimotor mu rhythm, also known as mu wave, comb or wicket rhythms or arciform rhythms, are synchronized patterns of electrical activity involving large numbers of neurons, probably of the pyramidal type, in the part of the brain that controls voluntary movement.

The sensory motor rhythm (SMR) is a specific brainwave frequency range that is associated with sensorimotor integration and motor control. It falls within the frequency band of 12 to 15 hertz (Hz), which is considered a subset of the beta brainwave range. It …
