Answer:
corollary discharge.
Step-by-step explanation:
Corollary discharge signal wass coined in 1950 by a man named Sperry, corollary discharge signal is a kind of neuron signal that converts a motor command. The converted motor command is then sent to a brain comparator. The brain comparator is for the comparision of intended movement movement with the reafference.
It must be noted that corollary discharge is a copy, and this copy itself does not generate locomotion. Corollary discharge will send warnings to brain region instead.
Completing the fill in question;
The COROLLARY DISCHARGE signal is sent to other areas of the brain relaying the message that a signal has been sent from the motor cortex to the eye muscles.
