The ups and downs of beta oscillations in sensorimotor cortex
TL;DR: It is found that there are additional processes that also strongly affect sensorimotor beta oscillations, such as visual cue anticipation and processing, fitting with the view thatbeta oscillations reflect heightened Sensorimotor transmission beyond somatosensation.
Journal ArticleDOI
Propagating waves in human motor cortex.
TL;DR: This study shows that the two properties of propagating beta waves are present in MI of a tetraplegic human patient while he was instructed to perform an instruction delay center-out task using a cursor controlled by the chin and demonstrates that traveling beta waves in MI are a general phenomenon occurring in human as well as NHPs.
Journal ArticleDOI
Daily training with realistic visual feedback improves reproducibility of event-related desynchronisation following hand motor imagery.
TL;DR: Realistic feedback training is a suitable method to acquire the skill to control a BCI system and highlights the possibility of improvement of reproducibility of ERD.
Journal ArticleDOI
Brain oscillatory signatures of motor tasks
TL;DR: The neurophysiological bases of an EEG-oscillation-driven BCI combined with a neuroprosthetic device are investigated to define the specific oscillatory signature of the BCI task, indicating neural processes unique to the use of body actuators control in a BCI context.

TL;DR: It is suggested that sensorimotor activation elicited by action observation enhanced motor learning according to motor performance, corresponding to a more efficient activation of cortical resources during task execution.

An on-line transformation of EEG scalp potentials into orthogonal source derivations
TL;DR: A new type of EEG derivation has been investigated, which detects source activity as it appears at the surface level of the scalp, and is realized in the 10-20 system of electrode placement basically as an analogue superposition of four bipolar derivations, forming a star-like configuration around each electrode.
Journal ArticleDOI
Motor imagery activates primary sensorimotor area in humans
TL;DR: The spatiotemporal patterns of Rolandic mu and beta rhythms were studied during motor imagery with a dense array of EEG electrodes and the pattern of EEG desynchronization related to imagination of a movement was similar to the pattern during planning of a voluntary movement.
Journal ArticleDOI
Alteration of proprioceptive messages induced by tendon vibration in man: a microneurographic study.
TL;DR: These data confirm that vibration is able to preferentially activate the Ia afferent channel, even when the vibration amplitude is low, and show that the physiological messages triggered by ongoing motor activities undergo a series of changes during the exposure of muscles to vibration.
Journal ArticleDOI
Spatiotemporal characteristics of sensorimotor neuromagnetic rhythms related to thumb movement.
Riitta Salmelin,Riitta Hari +1 more
TL;DR: It is hypothesize that the 10-Hz signal is a true somatosensory rhythm whereas the 20-Hz activity is essentially somatomotor in origin.

Kinaesthetic role of muscle afferents in man, studied by tendon vibration and microneurography
Jean-Pierre Roll,J P Vedel +1 more
TL;DR: The characteristics of the vibration-induced illusory movements and the muscle spindle responses to tendon vibration and to active and passive joint movements strengthened the possibility of the contribution of primary endings to kinaesthesia, as suggested by several previous works.
