Document Summary
A control system with preprogrammed instructions to an effector that does not use: feedback, error detection, correction mechanisms. Instructions sent to effector (body part making movement) Output what we see in the environment. We are getting no feedback in the environment mostly because we have no reference mechanism. Removed dorsal root ganglion afferent information (sensory) Did this to look at one upper limb. Although movement was limited, it was still there. Removing the midbrain prevented motor commands from leaving the brain. Also prevented sensory information coming from the periphery into the brain. Midbrain important for motor control sensory, incoming and outgoing information. In order for the cat to walk, they have to bolt the them up to a bar on the treadmill cat is completely. Whether the treadmill is going forward or backward, the gait changes to permit walking. With the mechanical input of the treadmill, walking is possible. If you speed the treadmill up, they"ll run.
