Abstract

The ERP signals describe the concentrated electrical activity of the brain in response to an external event. ERPs exhibit variations in latency, strength and location between various instances of the same event. Also, different population groups can show similarities in the characteristics of their ERPs and this fact is used by clinicians in diagnosis and monitoring of some specific psychiatric diseases. In this paper, we model the ERP components as transient spikes and use them as reference signals. We employ a novel localisation procedure utilising spatial notch filters and the information from the modelled ERP. The algorithm accurately localises the ERP sources within a noisy environment. © 2007 EURASIP.
