DHPG-evoked IPSCs do not depend on internal calcium stores. A, Application of DHPG in the presence of CPA (100 μm) still induced a large increase in the occurrence of IPSCs in mitral cells. The slice was bathed in CPA for 20 min before the application of CPA plus DHPG. B, Cumulative probability plot of interevent intervals for CPG plus DHPG (black line) and control CPA (gray line). Inset shows event rates for both conditions (CPA only, 0.37 ± 0.17 Hz; CPA plus DHPG, 8.23 ± 2.27 Hz; n = 5).
