Abstract
Spatial sampling must follow the same sampling constraints as temporal sampling. We attempted to oversample human epileptiform (spike) EEG activity and then downsampled to visually gauge the effect of undersampling. 128 channels were more than adequate for the small data set used thus far, but further studies are warranted
