Deviant tones embedded in a sequence of standard tones elicit an event-related potential (ERP) component called the mismatch negativity (MMN), which reflects automatic stimulus change detection in the human auditory system. To determine whether stimulus change detection is impaired in Parkinson's disease (PD), we recorded ERPs in 13 non-demented patients with PD and in 11 age-matched healthy control subjects both when tones were attended and when they were unattended.
