Amplitude, signal to noise ratio, time to peak, decay time for 1 ms light flash visual stimulation-evoked responses in anesthetized Emx-CaMKII-iGluSnFR, Emx-CaMKII-GCaMP6s and Emx-GCaMP3 mice, as well as RH1692 VSD imaged mice

ΔF/F(%)Time to peak (ms)Decay τ1/2 (ms)*SNR
Ai85 - iGluSnFR (n = 11)0.37 ± 0.0367.55 ± 6.5456.04 ± 11.2644.69 ± 6.11
RH1692 - VSD (n = 4)0.47 ± 0.0751.93 ± 1.6826.80 ± 6.1237.01 ± 8.77
Ai38 - GCaMP3 (n = 12)0.42 ± 0.05406.38 ± 52.03207.42 ± 19.7847.55 ± 3.89

  • *The decay time reflects the time to 50% of peak amplitude, which for Ai85 and RH1692 occurred over the fast initial component of the response (see Figure 7B).
