Product features
The mouse auditory brainstem response test system (ABR) induces and records the potential response of the cerebral cortex by giving different intensities of acoustic stimulation, so as to judge the hearing loss. It is often used in hearing screening and hearing threshold evaluation. Our device has four channels and can test the auditory brainstem response of four mice at the same time. Auditory brainstem response is a short latency potential, which can be used to distinguish hearing loss, brainstem lesions and acoustic neuroma. The test of auditory brainstem response in mice can help researchers carry out hearing related research.
