Intra-aural reflexes elicited by a cochlear prosthesis in monkeys
Hearing Research
|November 1, 1984
Summary
Cochlear prostheses can elicit intra-aural reflexes in monkeys, measured by threshold, latency, and amplitude. This electrically elicited reflex may aid in evaluating the auditory system of deaf patients unable to provide subjective feedback.
Area of Science:
- Neuroscience
- Audiology
- Biomedical Engineering
Background:
- Objective audiological tests are crucial for evaluating cochlear prosthesis patients who cannot provide subjective responses.
- Assessing the efficacy of cochlear implants requires reliable methods for patients with profound hearing loss.
Purpose of the Study:
- To investigate the elicitation of contralateral intra-aural reflexes using a cochlear prosthesis in a non-human primate model.
- To determine the feasibility of using electrically elicited reflexes for audiological assessment.
Main Methods:
- Monkeys were implanted with cochlear prostheses.
- Contralateral intra-aural reflexes were elicited by the prosthesis.
- Reflex variables including threshold, latency, and amplitude were measured.
Main Results:
- Cochlear prostheses successfully elicited contralateral intra-aural reflexes in the tested monkeys.
- Measurable reflex variables (threshold, latency, amplitude) provided objective data.
Conclusions:
- The electrically elicited intra-aural reflex response is a viable objective measure.
- This reflex may serve as a valuable tool for evaluating the peripheral auditory system in individuals with sensory deafness and cochlear implants.
