Fig. 5. Quinine-sensitive K2P channel is the best candidate for the astrocytic K+ uptake as the main source of activity-dependent IOS. (A) Schematic diagram of the source of K+ uptake. (B, E, H, K, N) Representative traces of IOS. Inset: Representative traces of fEPSP. (C, F, I, L, O) The percentage of IOS peak (paired t-test (two-tailed), *p<0.05, ***p<0.001, NS p>0.05). (D, G, J, M, P) The amplitude of fEPSP (mV) (paired t-test (two-tailed), *p<0.05, **p<0.01, ***p<0.001, NS p>0.05).
