From: Using a standalone ear-EEG device for focal-onset seizure detection
Example ear-EEG waveforms from a subclinical focal seizure detected during sleep. A 10 s window of interest is expanded in (a) and indicated in (b) by the “Zoom” region (blue), which falls within the full seizure annotation (white). Corresponding epileptologist annotations of seizure events are shown at the bottom of each plot, where the color-coded label “#1 (blinded)” refers to Reviewer #1’s annotation of the seizure made with access only to the ear-EEG system. ACC_Y: y-axis accelerometry from ear-EEG device; ELW-ELC: intra-ear left channel of ear-EEG; ERW-ELW: inter-ear canal channel of ear-EEG; ECG1: electrocardiogram channel; 11Ld10: the 10th recording site (equally spaced, with the 1st being deepest) along stereo-EEG depth electrode #11 placed on the left side of the head
