WebAug 1, 2007 · Negative feedback can speed up the system when the resonant frequency is higher than the CPG's baseline. The stronger the sensory input, the wider the range of resonant frequencies the CPG can use. By contrast, positive feedback slows the system down, but only if the input has just the right strength. With a weak input, the CPG just …
