Fig. 4 — Vglut2-positive cells exhibit specific intrinsic properties. a Schematic of viral injection of ChR2-eYFP in Vglut2-CRE RN and in vitro whole-cell patch-clamp recordings. b Light induced-currents and firing activity in identified cells. c Input-output curves (n = 6 cells/group). d Capacitance distribution of Vglut2-positive and Vglut2-negative cells (n = 31 cells/group). e Capacitance, t(60) = 9.12, P < 0.0001. f Rheobase, t(8) = 2.77, P = 0.0244 (n = 8–12 cells/group). g Saturating current, t(10) = 4.27, P = 0.0016. h Maximal firing, t(10) = 4.38, P = 0.0014. i Action potential width, t(17) = 3.01, P = 0.0067. j Resting membrane potential. (n = 6 cells/group). All data are reported as mean and SEM. Data obtained from photo-identified Vglut2-positive neurons are shown in blue (Vg+) whereas those light-insensitive Vglut2-negative neurons are displayed in grey (Vg−)
