Eye movements were investigated in cats while following a visual target. Wire coils implanted into the eyes served as transducers; the animal was placed in a revolving magnetic field (the magnetic search coil technique). The linear nature of amplitude-velocity relationships in saccadic eye movements was demonstrated. With combined head and eye movements, slope of plot was unrelated to maximum velocity of head movement over the entire test range (of up to 250 deg/sec); saccades decelerated when the head was immobile. Duration of gaze shift rose as it increased in amplitude. Amplitude of gaze was found to depend on head velocity. Experimentally obtained data on the interaction between head and eye movements when combined in following a target may be interpreted from the aspect of a mechanism operating to suppress saccadic signals by an 'efferent copy' signal for head movement.
