Abstract :
The present study focused on changes in P300 of the event-related potential (ERP) in subjects with Parkinson´s disease (PD). Changes in latency and amplitude of P300 are very useful indicators that can be used for clinical diagnosis. A low signal-to-noise ratio of the ERP signals makes it difficult to estimate small changes in latency and amplitude. In this paper, we propose a new method based on least mean square (LMS) algorithm to estimate the latency and amplitude changes of the ERP P300 response in real-time
