title: What drives corticospinal output?
abstract: Recent work has not only defined the origin of the direct cortico-motoneuronal output to the upper limb but has also identified some of the cortical networks that engage the corticospinal output during movement. A surprising finding is that some corticospinal neurons show 'mirror-like' properties and are actively modulated not only during self-movement but also during action observation.
