Handedness is associated with less common input to spinal motor neurons innervating different hand muscles
Résumé
How the neural control of manual behaviours differs between the dominant and non dominant hand remains poorly understood. This study shows that there is less common synaptic input between motor neurons innervating different muscles in the dominant than in the non dominant hand during isometric rotation tasks. This lower level of common input could confer higher flexibility in the recruitment of motor units.
