Comparison of velocity waveforms of eye and head saccades

Ann N Y Acad Sci. 2005 Apr:1039:477-9. doi: 10.1196/annals.1325.048.

Abstract

We compared the velocity waveforms of head and eye-in-head movements during eye-head saccades over a range 5-50 degrees. The velocity waveforms of eye-in-head saccades showed a skew ratio (acceleration period/saccade duration) that varied as a function of saccade size and duration. The velocity waveforms of head saccades showed a more constant skew of approximately 0.5 for the range of movements tested. These results suggest independent system controllers for eye and head components of eye-head saccades.
