Figure 2.
Topography of eye blinks. Maps from 12 individual subjects display the typical anterior topography of eye blinks as identified by independent component analysis (ICA) in EEG data (see also the text in the “Preprocessing and Analysis” section for more detail on the method). Nose is at top, inion at the bottom, and left and right hemispheres appear on the left and right. The color scale depicts arbitrary units.
