A. Schematic illustrating three combination-mode bouton clusters that exhibit similar preferences for either horizontal motion (left), On (middle), or vertical motion (right). An axon selective for horizontal motion and On (blue) could participate in the first two clusters, while an axon selective for vertical motion and On (orange) could participate in the last two clusters.
B. Percentage of divergent axons in each FOV (blue dots) that contain boutons innervating different types of functional clusters (combination-mode clusters with common axis preference or OnOff preference, or relay-mode clusters that share both preferences). Mean ± s.e.m.
