The auditory brainstem response (ABR), also called brainstem evoked response audiometry (BERA) or brainstem auditory evoked potentials (BAEPs) or brainstem auditory evoked responses (BAERs) [1][2] is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp.

2023年1月12日 · Auditory brainstem response (ABR), or brainstem auditory Evoked Potentials (BAEP), is an objective measurement of auditory pathway function from the auditory nerve to the mesencephalon. ABR tests synchronous neural function and can estimate hearing sensitivity thresholds in individuals unable to tolerate traditional behavioral audiometry. [1]

1993年8月1日 · ABR showed a differential expression pattern in various mouse tissues, analogous to that of BCR, and the highest level was found in brain. Similar to BCR, ABR contains a region with homology to DBL, vav, and CDC24, which are likely to or have been shown to encode GTP exchange factors.

2021年12月22日 · This review summarizes the animal and human studies that have investigated the ABR as a measure of cochlear synaptic function, discusses factors that may have contributed to the mixed findings and the lessons learned, and provides recommendations for future use of this metric in the research and clinical settings.

Subtracting the sum of left and right monaural auditory brainstem responses (ABRs) from the corresponding binaural ABR isolates the binaural interaction component (ABR-BIC). In a previous investigation (Ikeda, 2015), during auditory yet not visual tasks, tone …

2021年10月1日 · An oft-measured deflection of the binaural interaction component (BIC) is the DN1 component of the human auditory brainstem response (ABR). This negative deflection reflects the reduced amplitude of the binaural response relative to the sum of each monaural response (Dobie and Norton, 1980; Ito et al., 1988; Jiang, 1996; Levine, 1981; Polyakov ...

1993年8月15日 · In the present study, genomic ABR sequences were used to isolate human ABR cDNAs. Surprisingly, the two types of ABR cDNAs identified differed only in their most 5' coding sequences. These are predicted to encode proteins of 93.5 and 92.3 kDa molecular mass.

2015年9月28日 · The model fits latency-vs-intensity functions observed in human ABRs and otoacoustic emissions while maintaining rate-level and threshold characteristics of single-unit AN fibers. The simulations help to reveal which tonotopic regions dominate ABR waveform peaks at different stimulus intensities.

2024年10月31日 · The auditory brainstem response (ABR) is an essential diagnostic indicator of overall cochlear health, used extensively in both basic research and clinical studies. A key quantification of the ABR is threshold, the lowest sound level that elicits a ...

Early neural responses to acoustic signals can be electrically recorded as a series of waves, termed the auditory brainstem response (ABR). The latencies of the ABR waves are important for clinical and neurophysiological evaluations.
