Top: schematic of experimental configuration for widefield calcium imaging of visual cortex (VCx) in response to stimuli consisting of moving dots under control condition (left) and tetrodotoxin (TTX) silencing of superior colliculus (SC; right). Bottom: example F/F (120 trial average) across visual areas before (left) and after (right) TTX injection in SC. Cortical visual areas delineated as shown in Figure S1. POR, postrhinal cortex; LI, laterointermediate area; P, posterior area; LM, lateromedial area; AL, anterolateral area; AM, anteromedial area; PM, posteromedial area; RL/A, rostrolateral/anterior areas; V1, primary visual cortex. Orientation: A, anterior; M, medial.
