Examples of reconstructed spatiotemporal stimuli from model population responses. Each stimulus contains a set of objects moving toward the viewer and covers a visual angle of ∼120 × 120°. Reconstructions were performed with a ganglion cell density matching the mouse retina (∼20,000 model cells for a stimulus this size). A, The reconstructions of a stimulus consisting of moving light objects are largely similar for virtual retinas consisting of both ON and OFF RGCs (second row), only OFF RGCs (third row), and only ON RGCs (bottom row). B, The reconstruction for a stimulus consisting of moving dark objects is markedly altered when only ON RGCs are present: compared to the reconstruction based on the mixed population (second row) or the OFF RGCs only (third row), the reconstruction based on a population of only ON RGCs (bottom row) has several spurious objects.
