A new off-line procedure for dealing with ocular artifacts in ERP recording is described. The
procedure (EMPC) uses EOG and EEG records for individual trials in an experimental
session to estimate a propagation factor which describes the relationship between the EOG
and EEG traces. The propagation factor is computed after stimulus-linkes variability in both
traces has been removed. Different propagation factors are computed for blinks and eye
movements. Tests are presented which demonstrate the validity and reliability of the�…
