Why do higher frequencies need brighter signals to be detected?

Why do higher frequencies need brighter signals to be detected?

Hello dear Prophesee support team,

In my experiments I realized in a constant brightness level higher frequencies signals (exp. 1KHz) cannot be detected as much as lower frequency signals (exp. 10~100Hz); meaning much less events are detected in higher frequencies. Thus can we conclude higher frequencies need brighter signals, why does this happen?
