Observing how others lift light or heavy objects: Which visual cues mediate the encoding of muscular force in the primary motor cortex?

摘要

Observers are able to judge quite accurately the weights lifted by others. Only recently, neuroscience has focused on the role of the motor system to accomplish this task. In this respect, a previous transcranial magnetic stimulation (TMS) study showed that the muscular force requirements of an observed action are encoded by the primary motor cortex (M1).
