Abstract

Electrocorticogram (ECoG) from neighboring electrode locations contains a certain amount of redundancy. In order to take advantage of this redundancy to improve event-related potential (ERP) detection accuracy, four methods of multi-channel combination were tested. The best performance was achieved with the cross-correlelogram averaging method, which improved detection on 65% of electrode combinations
