Integration time for a low contrast RSVP stimulus. (A) The amplitude of the OFF-response is divided by the amplitude of the ON response. A small value (yellow arrow point to the right axis) indicates that the influence of the history is minimal and thus, that the stimulus is represented. (B) Index (y-axis) as a function of priming image duration (x-axis) for three different contrasts for animal 1 (10% = light gray, 25% = gray, and 100% = black). (C) Index (y-axis) as a function of priming image duration (x-axis) for three different contrasts for the more contrast sensitive animal 2 (2% = light gray, 5%= gray, and 10% = black). Note that when the contrast is low the index remains relatively small for durations up to 50 ms.
