Lack of bilateral coherence of mu rhythm

Electroencephalography and Clinical Neurophysiology, 1978
An investigation has been carried out in 25 normal subjects on quantitative differences of mu rhythm and alpha rhythm parameters. The parameters were frequency, average power over 102 sec and bilateral coherence. It was found that: (1) in the majority of cases the frequencies of the mu rhythms were higher than those of the alpha rhythms; (2) in the ...

Mu and alpha rhythm in comatose children

Child's Nervous System, 1985
Three anoxic comatose children had EEG alpha-like activity and in two of them mu rhythm was recorded. The paradoxical appearance of these electrical activities in comatose children seems to indicate a grave prognosis. A possible role for barbiturate treatment in this phenomenon is not excluded.

Foot and hand area mu rhythms

International Journal of Psychophysiology, 1997
Spontaneous EEG can display spatio-temporal patterns of desynchronized or synchronized alpha band activity. Event-related desynchronization (ERD) of rhythms within alpha and lower beta bands is characteristic of activated cortical areas ready to process information or to prepare a movement, while event-related synchronization (ERS) in the same ...

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 ...

An Analysis of Mu Rhythm Desynchronization in Virtual Reality Locomotion

2024 IEEE 12th International Conference on Serious Games and Applications for Health (SeGAH)
Movement Observation (MO), which refers to humans' perception of movement, significantly influences user cognition and behavior in Virtual Reality (VR) environments. It has the potential to influence immersion and effectiveness of the VR experience. This

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.

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%).

Acetaminophen changes Mu rhythm power related to pain empathy

Neuropsychologia, 2023
Empathy 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

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 ...

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 ...
