Sound offset-related brain potentials show retained sensory processing, but increased cognitive control activity in older adults


It has been hypothesized that age-related hearing loss is caused not only by peripheral, but also central changes in the auditory system. Many studies utilized event-related potentials (ERPs) elicited by sound onsets to characterize age-related differences in central auditory processing. Age-related ERP enhancements in such studies have often been interpreted in terms of elevated sensitivity to auditory stimulation. Such ERPs, however, comprise various components reflecting different aspects of auditory and task-related processing.📍
