Australian BioResources (ABR) is a state-of-the-art facility for breeding and holding research mice, owned and operated by the Garvan Institute of Medical Research on behalf of the medical research community in Australia.

The auditory brainstem response (ABR) test provides information about the inner ear (cochlea) and the central pathways for hearing. The ABR reflects the electrical responses of both the cochlear ganglion neurons and the nuclei of the central ...

Jun 17, 2022 · Here, we describe a protocol for recording ABR in mice using four-channel equipment. We detail the procedures of animal preparation, the setup of the ABR recording system, the click- and tone burst-evoked ABR recordings, and data analysis.

Mar 20, 2016 · The auditory brainstem response (ABR) test provides information about the inner ear (cochlea) and the central pathways for hearing. The ABR reflects the electrical responses of both the cochlear ganglion neurons and the nuclei of the central auditory pathway to sound stimulation (Zhou et al. , …

To further assess the hearing sensitivity with ABR, we have studied the ABR threshold as well as the variation in amplitude and latency of ABR components as a function of stimulus intensity in 10 different inbred strains of mice.

The ABR is an electroencephalographic response measured with scalp electrodes. It provides a quick, easy, and reliable method for physiological assessment of auditory sensitivity in mice.

Jan 3, 2022 · Here we describe a detailed ABR test procedure in mice using Tucker-Davis Technologies (TDT) hardware integrated into a custom system. The general procedure, however, can be adapted to use for other systems, experimental objectives, and other small mammals.

Dec 1, 2023 · Auditory brainstem responses (ABR) are a high-throughput assessment of auditory function. Many studies determine changes to the threshold at frequencies that span the normal hearing range of their test subjects, but fewer studies evaluate changes in waveform morphology.

Mar 16, 2022 · Here, we describe a protocol for recording ABR in mice using four-channel equipment. We detail the procedures of animal preparation, the setup of the ABR recording system, the click- and tone burst-evoked ABR recordings, and data analysis.

Nov 1, 2016 · In mice, the auditory brainstem response (ABR) is frequently used to assess hearing status in transgenic hearing models. The diagnostic value of the ABR depends on knowledge about the anatomical sources of its characteristic waves. Here, we studied the contribution of the inferior colliculus (IC) to the click-evoked scalp ABR in mice.
