Document Summary

Planning a movement entirely in advance of actually executing a movement. A control system with preprogrammed instructions to an effector that does not use: feedback, error detection, correction mechanisms. Getting commands from the brain (cns) and sending it and getting all of the instructions at once that tell (cid:455)ou ho(cid:449) to (cid:373)o(cid:448)e (cid:271)ut it does(cid:374)(cid:859)t use feed(cid:271)a(cid:272)k, does(cid:374)(cid:859)t dete(cid:272)t e(cid:396)(cid:396)o(cid:396), a(cid:374)d does(cid:374)(cid:859)t use correction mechanism.

In open-loop, we have an input then it goes to the executive level (cns) then to the effector (muscle) then output (what we see in the environment.

The dorsal root is associated with our sensory information. Found that although the movement was limited, there still was movement. Looked at de-afferent a disease in the sensory info.
