Dynamics of Smooth Pursuit Maintenance

Abstract: Tavassoli A, Ringach DL. Dynamics of smooth pursuit maintenance. J Neurophysiol 102: 110 -118, 2009. First published April 15, 2009 doi:10.1152/jn.91320.2008. Smooth pursuit eye movements allow the approximate stabilization of a moving visual target on the retina. To study the dynamics of smooth pursuit, we measured eye velocity during the visual tracking of a Gabor target moving at a constant velocity plus a noisy perturbation term. The optimal linear filter linking fluctuations in target velocity to evoked … Show more

“…The filters were much longer than the impulse response of the eye velocity differentiator, which was 7.5 ms. The temporal properties of the filters we obtained in monkeys were somewhat narrower than those reported by Tavassoli and Ringach (2009) …”

“…For the temporal noise experiments, we described the temporal relationship between eye and target velocity by computing the linear filter, h(), that best predicts the pursuit response to a given target motion (Mulligan 2002;Papoulis 1991;Tavassoli and Ringach 2009;Weiner 1949). The linear filter is defined for continuous signals by:…”

“…A similar switch was shown for the motor system, making the response of the eyes' response to small speed perturbations during pursuit stronger (Tanaka & Lisberger, 2001) and faster (Tavassoli & Ringach, 2009). What is the purpose of the sensitivity change?…”

“…Latencies are only about 100 ms, and pursuit dynamics are fast in response to random perturbations to the motion introduced while pursuit is already underway. Many showed this: Tavassoli & Ringach in 2009; Osborne & Lisberger in 2009; Schwartz & Lisberger in 1994; and Churchland & Lisberger in 2002. So why bother with anticipation?…”
