Efferent cortico-visual projections from V1. Shown is a top view of mouse neocortex based on the Allen common coordinate framework v.3. Robustness of efferent projections to and from V1 is illustrated for the wild-type mouse, rank ordered according to the density of projections of visual cortex adjusted for injection size. The inputs from most robust to least robust were: (1) the anterolateral visual area (VISal/AL), (2) the lateromedial visual area (VISlm/LM), (3) the rostrolateral visual area (VISrl/RL), (4) the lateral intermediate visual area (VISli/LI), (5) the posteromedial visual area (VISpm/PM), (6) the posterior visual area (VISp/P), (7) the anteromedial visual area (VISam/AM), (8) the postrhinal visual area (VISpor/POR), and (9) the anterior visual area (VISa/A).
