Amplitude Change with Click Rate in Human Brainstem Auditory-Evoked Responses

Influence of cochlear traveling wave and neural adaptation on auditory brainstem responses

“…This was the case even for a within-train rate of 47.6 Hz. This rate lies within a range for which a strongly reduced wave-V amplitude was observed in other studies (Thornton and Coleman, 1975;Jiang et al, 1991). The eVect of within-train rate on wave V for the chirp was investigated further in experiment 3.…”

“…In those studies investigating the eVect of click rate, ABR latencies generally increased and ABR amplitude decreased as click rate increased. For example, Jiang et al (1991) found a 33% decrease in wave-V amplitude when the click rate was raised from 10 to 90 Hz at 40 dB hearing level (HL). Scott and Harkins (1978) found an amplitude decrease of 19% when increasing the rate from 10 to 100 Hz.…”

Auditory Brainstem Responses with AEP_AUDIX system using an optimized broadband chirp stimulus

“…In those studies, ABR latencies generally increased and ABR amplitude decreased as click rate increased [21][22][23]. In the second experiment, with respect to temporal processing, the influence of repetition rate on wave-V amplitude for the chirp-evoked ABR was investigated.…”

“…Experiments: Two experimental series were performed: in the first, ABR elicited by click and broadband chirp were obtained (stimulus level: ~60 dB nHL /repetition rate: 21/s) and compared wave-V amplitude for the two stimuli; in the second, chirp-evoked ABR were obtained at different repetition rates (17,21,33, 55, 71, 77 and 89/s) with respect to investigated their possible influence in the temporal processing.…”

Steady-state analysis of auditory evoked potentials over a wide range of stimulus repetition rates: Profile in adults

“…Upon the assumption of the general correspondence -between transient-AEP latency windows and periods of ASSR componentsa transient rate-based profi le was created based on the AEP literature (Aoyagi et al, 1993;Jiang et al, 1991;Lasky, 1984;Martin et al, 1988;Salamy et al, 1978Salamy et al, , 1982Tucker & Ruth, 1996). Figure 1 displays the transient rate-based profi le, which like the ASSR, emphasizes main peaks around 40 Hz, between 10 and 20 Hz, and again at 80 Hz.…”
