Action potential blocking for cathodic stimuli would produce non-monotonic neural growth patterns.

Evidence

If, at some level in the dynamic range, action potentials are being blocked for cathodic stimulation, this should be reflected by a slower rate of increase of the neural response for cathodic than for anodic stimulation and/or potentially by a non-monotonic growth of response amplitude as a function of current level. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2277
