Figure 2. — Relation between eye-tracking measures and EPI Orbit (EO-EPI) regressor. (A) sample time window showing relationship between raw EO-EPI signal, EO-EPI Envelope used for Kernel computation, and pupil size and gaze power measures derived from simultaneously acquired eye tracking data. (B) two Kernels estimated as relating the relationship between the EO-EPI envelope and pupil size (gray) or gaze power (green). Note that peaks in eye-tracking gaze power (time = 0) precede a peak in EO-EPI envelope by around 2 sec.
