Mu rhythm suppression during the imagination of observed action
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013Mu wave suppression is thought to accompany the activation of the mirror neuron system which occurs when a human observes or imitates the behavior of others. Our investigation indicates a possible difference in mirror neuron system activation between passive and more active observation as suggested by mu wave activation levels.

The Rolandic Mu Rhythm: A Clinical Study of the Atypical Group
Clinical Electroencephalography, 1992We studied 241 patients whose electroencephalograms (EEGs) showed 7-13 Hz arch shaped wave patterns (mu rhythm) that are known to appear in the Rolandic area. The patients were then classified into two groups depending on the conditions of appearance of the mu rhythm. Group I (typical group) consisted of 171 cases.

Individual Characteristics and Their Effect on Predicting Mu Rhythm Modulation
International Journal of Human-Computer Interaction, 2010Brain–computer interfaces (BCIs) offer users with severe motor disabilities a nonmuscular input channel for communication and control but require that users achieve a level of literacy and be able to harness their appropriate electrophysiological responses for effective use of the interface.

EEG mu rhythm suppression is assessed in experiments on the execution, observation and imagination of movements. It is utilised for studying of actions, language, empathy in healthy individuals and preservation of sensorimotor system functions in patients with schizophrenia and autism spectrum disorders.

Mu rhythm modulation during changes of visual percepts
Neuroscience, 1999Cooperation between vision and somatomotor behavior, such as manual exploration of objects, suggests close functional coupling between the visual and sensorimotor systems. We observed this type of interaction in human volunteers during binocular rivalry while following the level of sensorimotor mu rhythm with a whole-scalp neuromagnetometer.

Speech perception, production, and the sensorimotor mu rhythm
Proceedings of the 2014 Biomedical Sciences and Engineering Conference, 2014The EEG mu (μ) rhythm is considered a measure of sensorimotor integration. This rhythm is commonly identified by co-occuring peaks at ~10'Hz(alpha) and ~20 Hz (beta) across the sensorimotor cortex. Suppression of the power within peaks are thought to reflect somatosensory and motor aspects of processing respectively.

Action–perception connection and the cortical mu rhythm
2006The rolandic mu rhythm consists of two main frequency components: one around 10 Hz and the other around 20 Hz. Reactivity of the mu rhythm, especially its motor cortex 20-Hz component, provides an illuminating window to the involvement of the human sensorimotor system in the loop that connects action and perception with the environment.

[Various features of the mu-rhythm in epileptics].
Zhurnal nevropatologii i psikhiatrii imeni S.S. Korsakova (Moscow, Russia : 1952), 1984Out of 502 epileptics studied, 54 patients showed the mu-rhythm on the EEG which was more pronounced on the side of the epileptic focus. It was usually sharply shaped and often attended by the central beta-rhythm. The diagnostic value of the paroxysmal mu-rhythm is evident although the latter occurs rather rarely.

Rolandic Mu Rhythms and Assessment of Cerebral Functions
American Journal of EEG Technology, 1986ABSTRACT.Mu rhythms can be considered as intrinsic or resting activity of the central region. Somatosensory stimulations or motor behavioral activity affect the generation mechanism of mu rhythms and result in an amplitude attenuation or blocking reaction.
