Optimizing objective detection methods for auditory evoked responses

Michael Chesnaye

Auditory evoked responses are short changes in neural activity along the auditory pathway in response to a brief acoustic stimulus, such as a click, chirp, or tone burst. They are typically recorded non-invasively using surface mounted electrodes, and are used primarily for diagnosing abnormalities within the auditory system, such as hearing loss and various neurological disorders. Determining whether an ABR is present (by either inspecting the data manually, or by applying an objective statistical test) is usually the first step for these applications, after which additional analysis can be performed on, for example, the morphology of the response. The focus for this project is on optimizing objective measures for detecting the evoked response.
