From: Natural image and receptive field statistics predict saccade sizes
(a), Natural images were displayed to mice running on a floating Styrofoam ball, while we tracked eye position with infrared cameras and running speed with an optical mouse. (b), Saccades were detected when velocity exceeded an initial threshold (red dashed line), and the beginning (green circle) and end (red circle) of saccades were determined as when the velocity fell below a second threshold in opposite directions (green dashed line).
