The posterior parietal cortex and frontal cortical areas to which it connects are responsible for sensorimotor
transformations. This review covers new research on four components of this transformation process: plan-
ning, decision making, forward state estimation, and relative-coordinate representations. These sensori-
motor functions can be harnessed for neural prosthetic operations by decoding intended goals (planning)
and trajectories (forward state estimation) of movements as well as higher cortical functions related to deci-
sion making and potentially the coordination of multiple body parts (relative-coordinate representations).
Frontal and parietal areas are strongly interconnected and func-
tion 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
