Document Summary
Movement occurs through the interaction of the perception and action systems with cognition effecting both at different levels. Sensory information is processed at different levels and through different systems. Brain structures involved in motor control are organized hierarchically and parallel, meaning information can be processed in two ways. Hierarchically information is processed in ascending levels of the central nervous system. Higher levels of the brain interpret the sensory information and make a plan of action. That plan is sent to lower levels to execute. Parallel information is processed in many different structures at the same time. The same signal is processes simultaneously by different structures of the brain, before sending the action plan to be carried out by the motor cortex. Highest levels of control not only impact the next level down but can also act independently on the spinal motor neurons. Combination of both parallel and hierarchy allows a system to take over, overlap funtions.
