In vivo imaging of K-GECO1 in mouse V1 neurons. a Schematic setup of the experiment. b Image of V1 L2/3 cells expressing K-GECO1. c Example traces from neurons expressing K-GECO1. The direction of grating motion is indicated above the traces. d Fraction of cells detected as responding to the visual stimulus of K-GECO1 compared with previously reported values [24] from other red GECIs (n = 26 for RCaMP1h; n = 45 for jRCaMP1a; n = 30 for R-GECO1; n = 40 for jRGECO1a; n = 13 for K-GECO1). e Distribution of ΔF/F0 amplitude for the preferred stimulus of K-GECO1 compared with previously reported values [24] from other red GECIs.
