Fig. 3. Modulation of the time course of inhibitory postsynaptic currents by midazolam. Averaged and normalized spontaneous inhibitory postsynaptic currents recorded in four different cells in control conditions and in the presence of 1 μm midazolam ( A , same cell as in fig. 1,), 0.1 μm midazolam ( B ), 0.01 μm midazolam ( C ; same cell as in fig. 2 ), and 1 μm midazolam plus 5 μm flumazenil ( D ). Ctrl = control; Flu = flumazenil; Mdz = midazolam.
