Figure 5.

sPSCs recorded in NG2 glia are AMPA mediated. (A) sPSCs recorded during bath application of 100 μM 4-AP. A single event fitted to a monoexponential is shown with higher time resolution (right). (B) sPSCs recorded after preincubation with 100 μM CTZ and co-application of 100 μM 4-AP plus 100 μM CTZ. A single event, fitted to a monoexponential, is shown with higher time resolution (right). Note that the time decay constant (τ) under CTZ is slower than that observed with 4-AP alone. (C) 100 μM GYKI 52466 blocks the sPSCs completely. (D) Histograms of amplitude distribution (left) and time decay constants (right) under 4-AP and in the presence of CTZ. (E) Cumulative fraction for amplitude (left) and decay time constants (right).
