Area 2 of somatosensory cortex represents kinematic details of the entire arm during movement, but this mapping from limb state to neural activity differs for reaching and passive limb displacement.

To ensure smooth sequential actions, reaches to at least two future targets are planned during the execution of the current reach and the planning processes of the future reaches interact.
When Rhesus monkeys plan reaching movements of which they are not fully confident, a particular area of the brain represents both the chosen action as well as alternate movements, perhaps as an aid for error correction or learning.
Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.
Humans retrospectively localize touch after deciding on which limb it occurred, challenging the mainstream idea that tactile location in space is the basis for assigning touch to a body part.
