Coherence between magnetoencephalography and hand-action-related acceleration, force, pressure, and electromyogram

► MEG signals are coherent with kinetics, kinematics, and EMG of hand actions. ► Coherence occurs at the frequency of hand actions and its first harmonic. ► Both dynamic and fixed hand actions result in significant coherence. ► The coherent sources are located close to each other in the contralateral SM1 cortex. ► SM1 cortex can be located during natural actions with corticokinetic coherence.
