If temporally low-pass the Reichhardt outputs, all speeds represented in speed-modulated stimulus but not in unmodulated stimulus. If temporally low-pass the pre-filtering stage,wouldn't be able to perceive motion at high frequencies If delay stage is temporally low-pass,

integration interval

[2] found attention / central viewing dramatically increased motion integration interval, with max integration interval 10 sec as found by Burr and Santoro
