The Neurophysiology of Eye-Head Coordination (Paperback) (ISBN-13: 9783639045284)

Research was conducted in order to simulate real-life impacts during shifts of gaze in humans. The objective of the research was achieved by applying assisting and opposing torque loads during gaze shifts of human subjects through a servomotor. The subjects performed a simple visual task to guide their gaze shifts in the dark. The visual task led the subject s gaze towards eccentricities of a range within which the head s contribution to the gaze coordinated movement is in-dispensable. The novel gaze movement trajectories produced support the existence of a feedback control mechanism in the eye-head coordi-nation system that keeps track of the on-going movement and adjusts the movement s kinematics on-line accordingly. The addition of a neck-muscle generated mechanism that interferes with the vestibulo-ocular reflex and affects the eye s trajectory post-saccadically is here-by proposed as a complement to the existing neurophysiological feed-back models.
