[Coordination of eye and head movements in cats]

Horizontal displacements of gaze in cats with unrestrained head were studied using the magnetic search coil method. Three types of eye-head coordination were found when cats oriented gaze towards visual targets. Maximal velocities of gaze, head and eye movements in orbits depend linearily on amplitudes of their displacements in the range of up to 20 degrees. Gaze velocity reached its top level in about 0.3 of complete time of movement execution. Data support the idea of saccadic-vestibular summation during coordinated eye-head movements in cats.
