Fig. 4 Bino-PRNs receive input from the two eyes that are offset in horizontal space and correspond to objects at different distances from a hunting larva (A) Monocular and binocular tuning curves of three example bino-PRNs from one larva. Blue line represents the left eye response to stimuli presented at each azimuth, orange line represents the right eye response, and green is the binocular condition. Shading represents 1 SD. (B) Distribution of the distances between the peaks of the left eye and right eye receptive fields for all bino-PRNs. Degree values indicate distance between the best left-eye (LE) and right-eye (RE) stimulus in screen coordinates. (C) Schematic showing how left eye/right eye peak separations in the imaging preparation correspond to object distances at medium (60°) and maximum (75°) levels of convergence. Blue lines = 10° separation, purple lines = 30° separation, violet lines = 50° separation between right and left eye peaks. See also Figure S4.
