Insight into the neurophysiological mechanisms of brain–peripheral couplings and relevance for motor performances

Unité : Unité de Recherche en Neurophysiologie et de Biomécanique du Mouvement | ULB382

Description :

How the brain orchestrates sensorimotor control of various motor acts is still unclear. Of potential relevance to sensorimotor control are two
brain–peripheral coupling phenomena: Corticokinematic coupling (CKC), the coupling between brain and repetitive movement kinematics, and corticomuscular coupling
(CMC), the coupling between brain and muscle activity at 20 Hz mainly seen during steady muscle contractions. 
Both couplings can be revealed with scalp
electrophysiological recordings such as EEG and MEG. 
This project draws on movement biomechanics approaches to answer 3 major neuroscience questions: Which
aspects of the communication between the brain and the periphery do CKC and CMC support? 
To which extent these couplings are functionally/behaviorally
relevant? And what is the role of the cerebellum in maintaining these couplings? 
The key innovative element is the focus on the low frequency oscillations,
which hold the promise of being the medium of proprioceptive signaling, a central component of the most promising theory of sensorimotor
