Most published ECoG studies use common average reference (CAR) spatial filters to remove common noise, but CAR filters may introduce channel-specific noise into other channels. To address this concern, scientists often remove artifactual channels prior to data analysis. However, removing these channels depends on expert-based labeling and may also discard useful data. Thus, the effects of spatial filtering and artifacts on ECoG signals have been largely unknown. This study aims to quantify these effects and thereby address this gap in knowledge.10aYoung Adult1 aLiu, Y.1 aCoon, W., G.1 ade Pesters, A.1 aBrunner, Peter1 aSchalk, Gerwin  uhttp://www.ncbi.nlm.nih.gov/pubmed/26268446
