Intention, Action Planning, and Decision Making in Parietal
... Frontal and parietal areas are strongly interconnected and function together for many aspects of action planning. Historically, a role of frontal lobe in action has been clear (Fritsch and Hitzig, 1870; Ferrier, 1876). The primary motor cortex (M1) is a source of motor commands (Penfield and Boldrey ...
