Integration time for a RSVP stimulus. Response to a sequence of gratings with alternating orientations, i.e., preferred and non-preferred orientations. Four different image durations were tested; 250 ms (upper left), 100 ms (lower left), 50 ms (upper right), and 20 ms (lower right). For 250 and 100 ms, the second burst (at 300 and 150 ms, respectively) encodes the difference between the horizontal and vertical grating, i.e., the error signal containing information about both horizontal and vertical grating. For 20 and 50 ms, neurons can separate between the two orientations (see inset for average across all cycles).
