Stability and Source Analysis of Auditory Mismatch Negativity in Healthy Subjects

摘要

Backgroud: Mismatch negativity (MMN) is an eventrelated brain potential which can be triggered by deviant signals among repetitive stimuli. It indicates the measures of preattentional impaired deviance detection, while MMN deficit had been noted in many neuropsychiatric disorders. However, data regarding MMN in Chinese ethnicity are lacking. In current study, we obtained auditory duration MMN testing twice over a 4-week period to study the stability and source analysis in 10Taiwan healthy controls.
