Topic: efference copies

Performance of goal directed actions requires integration of motor commands with their expected sensory outcome. A prominent theory suggests that predictions of actions’ sensory outcome (‘efference copies’) are sent to relevant sensory regions and modulate their neural state, resulting in differential processing of the reafferent sensory signal. However, predictive signals are not unique to actions and can be associated with non-motor sources as well. It is an open question whether motor and non-motor predictive signals share common neural mechanisms. To address this question, we used fMRI and
