Human smooth pursuit eye movement responses to visual, auditory, and imagined target motion (2002)
It is widely believed that a moving visual target is required to drive robust smooth pursuit eye movements. However, some studies have reported low-gain pursuit of moving auditory targets (Hashiba et al, 1996; Paige et al, 2000; Krukowski et al, 2001). Here, we explore the possibility that this auditory pursuit might be a response to the motion of an imagined target, by comparing pursuit responses under 3 conditions: combined visual and auditory motion, auditory motion, and an imagined-motion condition in which the trajectory is cued only by brief, stationary, auditory presentations at its end points. We have also explored the dependence of pursuit under these 3 conditions to variations in amplitude and temporal frequency.
