E3-ESR: Physiological measurements of auditory steady state brain responses

Auditory steady state brain responses (ASSRs) were introduced as a new technique to assess temporal neural processing in different populations (e.g. hearing impaired, auditory processing disorders, dyslexia). In this project we aim to apply auditory stimuli at supra-threshold levels and detect the ASSRs in multichannel EEG recordings. The auditory stimuli to evoke brain responses (from auditory periphery to cortex) are modulated with rates from about 100 Hz to a few Hz, respectively. However, the ASSRs must be detected above the high, time-varying level of the background EEG spectrum, and, especially for young subjects, the measurement time should be as short as possible for attention issues. The development of sensitive and reliable objective measures based on ASSR will be a tool for improved application and fitting of auditory prostheses
