Mu rhythm, visual processing and motor control

Clinical Neurophysiology, 2012
The Mu-rhythm has been proposed as both an inhibitor ("idling hypothesis") and as a promoter ("processing hypothesis") of information processing in the primary sensory-motor cortex (SM-C). We tested these possibilities by analyzing the phase-locked and non-phase-locked Mu response during the execution of a visual-motor task.EEG was recorded in 13 ...

Enhancement of Rolandic mu-rhythm by pattern vision

Electroencephalography and Clinical Neurophysiology, 1975
Abstract In 61 patients with evidence of Rolandic mu-rhythm, a pattern vision test was performed (presentation of pictures). While scanning eye movements were elicited by this test, the mu-rhythm was enhanced in 33 patients (54%) and remained essentially unchanged in the remaining 28 patients (46%).

Functional topography of the human mu rhythm

Electroencephalography and Clinical Neurophysiology, 1978
Abstract Topographic and functional testing was conducted to determine if the Rolandic mu rhythm (rhytme en arceau) could be reliably detected from the human scalp, and to describe its spatiotemporal and functional characteristics in relation to the feline sensorimotor rhythm (SMR) and the human occipital alpha rhythm.

Mu rhythm-based cursor control: an offline analysis

Clinical Neurophysiology, 2004
To classify the EEG data recorded in mu rhythm-based cursor control experiments with 4 possible choices.The algorithm included preprocessing, feature extraction, and classification. Two spatial filters, common average reference and common spatial subspace decomposition, were used in preprocessing to improve the signal-to-noise ratio, and then two ...

The Rolandic Mu Rhythm: A Clinical Study of the Atypical Group

Clinical Electroencephalography, 1992
We 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, 2010
Brain–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.

Mu rhythm suppression during the imagination of observed action

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
Mu 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.

Mu rhythm separation from the mix with alpha rhythm: Principal component analyses and factor topography

Journal of Neuroscience Methods, 2020
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, 1999
Cooperation 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.

Altered mu-rhythm suppression in Borderline Personality Disorder

Brain Research, 2017
Borderline Personality Disorder (BPD) is characterized, among other symptoms, by interpersonal dysfunction and difficulties in empathizing. According to Simulation Theory empathy is linked to the activity of the mirror neuron system (MNS). Mu-rhythm desynchronization, as reflected in a suppression of electroencephalographic alpha-frequency bands (8 ...
