Figure 1.
Forward masking is defined as a decreased probe response, depicted by a reduced CAP (B), following a preceding masker. At short masker to probe intervals (MPIs), the ABR wave-V latency is delayed relative to the control (no preceding masker) as illustrated here in A and C. As the gap between the masker and the probe increases, the ABR wav-I amplitude increases (B) and wave-V latency decreases (C). Preferential deafferentation of low-SR fibers (dashed line in B and C) would hypothetically cause a faster recover of the ABR-I amplitude (B) and wave-V latency (C).
