Unravelling the effect of experimental pain on the corticomotor system using transcranial magnetic stimulation and electroencephalography.

abstract：:Traditional approaches to research on bimanual coordination focus on sensorimotor interference, motor programming, and effects of perception and feedback guidance; surprisingly, little is known about high-level conceptual constraints that might unify separate movements into coordinated actions. We investigated two pos...
