Comparison of Velocity Waveforms of Eye and Head Saccades

: 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 ∼0.5 for the range of movements tested. These results suggest independent system controllers for eye and head components of eye‐head saccades.
