These may include a hearing test (either the otoacoustic emission or the
automated auditory brainstem response tests,) car seat safety check, testing for an hyperbilirubinemia, and screening for heart disease.
The loss is greatest in the higher frequency range; at seven weeks, Henry reported 50 % of the mice showed no 64
kHz auditory brainstem response (ABR), and by 100 days both the 2 kHz and 32 kHz responses were absent.
Our hearing testing offerings include diagnostic audiology services, intra-operative testing,
auditory brainstem response (ABR) testing, inner ear evaluations, specialized screening for newborns, infants and toddlers and patients with cancer.
«Traditionally FFRs were called the «
auditory brainstem responses», so we were very surprised when our method revealed that they also included a big contribution from the cortex,» says Robert Zatorre, Professor of Neurology and Neurosurgery at McGill University, and senior author.
