Neural coding in the VRL/A/AL and the V1. a–c Coding in the VRL/A/AL. a GCaMP6f expression at layer 2/3 in the VRL/A/AL. The position of the VRL/A/AL was determined with fluorescent guidance of tdTomato-labeled projections from the MOs. b Representative cells. Corresponding ROIs are shown in a. c Sorted normalized ∆F/F responses for neurons showing significant response (n = 913). Traces were aligned to either the onset of the visual target or the movement in the contraversive movement condition. d–f Coding in the V1. d GCaMP6f expression at layer 2/3 in the V1. e Representative cells. f Sorted normalized ∆F/F responses for neurons with a significant response (n = 306). g–l Comparison between visual and motor activity for neurons in the MOs (g, h, n = 904), VRL/A/AL (i, j n = 913), and V1 (k, l, n = 306). g, i, k Visual and motor activity was plotted for each neuron. h, j, l The angle in polar coordinates was computed for each neuron and plotted as a histogram. Degrees of 0 or 90 indicate pure visual or motor activity
