Mice accurately judge distance under binocular and monocular conditions.
(A) Example jump trajectories from a single mouse (red line is trajectory of left ear tracked by DeepLabCut, blue dot is end point of jump) at three distances for binocular (top row) and monocular …

Binocular vs. monocular task performance.
(A) Rates of failure (left column), success (middle column), and abort trials (right column) for binocular (blue) and monocular (magenta) conditions.

Mice perform more head movements during the decision period under monocular conditions.
(A) Example decision period trajectory of the left eye position overlaid with movements identified through velocity zero crossings. Color corresponds to movement cluster identity in (B ,C). Image is …
