cells were classified as follows : pure-vestibular cells with firing rates modulated only by head velocity ( 15 % ) , vestibular-pause cells that were similar to the pure-vestibular cells but paused for saccades in all directions ( 10 % ) , gaze-velocity cells that modulated their rates in proportion to vertical eye velocity in space ( 7 % ) , position cells with rates modulated by changes in eye position in the head but that did not burst or pause during saccades ( 33 % ) , position-burst cells that also carried an eye-position signal but did burst during saccades in one direction and paused in the opposite direction ( 15 % ) , and position-vestibular-pause cells that carried signals proportional to eye position in the head and head velocity and paused during all saccades ( 20 % ) .
