Acetaminophen changes Mu rhythm power related to pain empathy
Neuropsychologia, 2023Empathy is an intricate ability that entails the subjective feeling and understanding of emotions someone else may be experiencing. Acetaminophen, the active ingredient found in Tylenol, is among the most common pain medications consumed. There is new evidence, however, that suggests this common analgesic may also dampen empathic processes. However, no

Mu rhythm-based cursor control: an offline analysis
Clinical Neurophysiology, 2004To 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, 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.

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.

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.

Altered mu-rhythm suppression in Borderline Personality Disorder
Brain Research, 2017Borderline 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 ...

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.

Mu rhythm modulation during observation of an object-directed grasp
Cognitive Brain Research, 2004Recent electrophysiological studies have shown that the human electroencephalographic mu rhythm is suppressed during the observation of actions performed by other persons, an effect that may be functionally related to the behaviour of so-called "mirror neurons" observed in area F5 of nonhuman primates.
