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

Units : Laboratory of Neurophysiology and Movement Biomechanics | 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. 
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 control.
