Using Open-Loop Experiments to Study Physiological Systems, With Examples From the Human Eye-Movement Systems
A. Terry Bahill, TM Hamm · Physiology · 1989
To analyze the contribution of each element in a sensory feedback control system, it is necessary to study the system with the feedback loop opened. Some physiological systems have multiple or even unknown sources of feedback, which makes it exceedingly difficult to open the loop. Conversely, it is relatively easy to open the loop on the human eye-movement system. Study of this system should help us understand how physiological control is maintained by sensory feedback.
