This subject generated a larger potential with
downward gaze than with upward gaze. Even with
the most extreme upward gaze of which he was
capable, the response was only about 20% larger
than that shown in Fig. 4 (downward deflections). It
is therefore of some interest that his blink response was also small in absolute amplitude and correlated
somewhat more closely with upward
movements (r=092) than with downward
movements (r=0-78).
