Document Summary
Sensory systems and their receptors provide important info for guiding movement. Motor systems and other systems that encode in a similar manner don"t understand sensory feedback since it is encoded in a different way: sensorimotor transformations are needed. Reference signal is required for sensory feedback to indicate how it deviates from an intended path or whether ether is an error in performance. Models that understand how the body works. Different bran regions are thought to be responsible for various aspects of the internal model. Inverse model calculates necessary motor commands from desired trajectory info and knowledge of where limb is at that movement. Forward model predicts sensory consequences of movement based on copy of motor command. Cognitive model model of how objects work based on prior experience with the object or one that is similar. Need to know state of limb and target to come up with motor plan and figure out trajectory.
