(A) Coronal slice containing visual cortex and LP, showing the injection site and retrogradely labelled neurons (green), tdTomato-expressing Colgalt2-Cre neurons (magenta), a DAPI stain (blue), and neurons that have been filled with biocytin during intracellular recordings and stained with DyLight 594 (cyan). (B) Biocytin-filled ttL5 neuron in V2m. (C) Neighbouring tdTomato-expressing Colgalt2-Cre neurons. (D) CTB-labelled L5 neurons projecting to LP. (E) Composite image of the above. Arrowheads highlight two example cells labelled by both tdTomato and CTB. (F) Schematic of coronal sections, adapted from Franklin and Paxinos, 2007, showing approximate mediolateral locations of V1 (red) and V2m (blue) neurons recorded in the cfADP experiments (90 out of the 129 neurons recorded in total). For visualization, neurons were projected onto the closest of the five atlas sections shown. (G) Approximate anteroposterior locations of the neurons relative to bregma.
