Binaural difference in rat

Abstract: The binaural difference (BD) is the sum of monaural acoustic brainstem responses (ABRs) minus the binaural ABR. Its construction implies operation of a nonlinear element with binaural input. The BD in five rats was studied using insert earphones that provided 60 dB of interaural isolation measured in the occluded external meatus. Scalp to chin BD consisted of a double-peaked complex with a following trough occurring during peaks IV and V of the sum of monaural ABRs. BD magnitude was defined as the maximum peak… Show more

“…3 indicates the ratio of these peaks is about 1.0 over a 40-dB increase in stimulus level. We have reported (Psaltikidou and Gaumond, 1989) that, in rat, the ratio of BD to BAER peak I is constant as stimulus level is varied.…”
