Input and Output Compensation for the Cochlear Traveling Wave Delay in Wide-Band ABR Recordings: Implications for Small Acoustic Tumor Detection

摘要

BackgroundThe Stacked ABR (auditory brainstem response) attempts at the output of the auditory periphery to compensate for the temporal dispersion of neural activation caused by the cochlear traveling wave in response to click stimulation. Compensation can also be made at the input by using a chirp stimulus. It has been demonstrated that the Stacked ABR is sensitive to small tumors that are often missed by standard ABR latency measures.
