Predictive saccade tracking (targets stepping back and forth at frequencies of 1.25 = 1.0 Hz) and self-paced saccades between two stationary targets were measured in patients with cerebellar degeneration and in normal subjects. Cerebellar patients produced similar predictive latencies and generated the same percentage of predictive saccades as did normal subjects. Only the variability in the self-paced saccade paradigm was different between the groups.
