Figure 4. Block of sodium channels does not reduce mEPSC frequency.

In A a recording epoch is shown before and in B after the addition of 1 μm TTX. The cPDFs of f₁ (C) and amplitudes (D) before (black line) and after the addition of TTX (grey line). In both C and D, the cPDFs are not different from each other. The average sPSC time courses are shown in the inset. E and F, the average mPSC frequencies and amplitudes (in TTX) are plotted against those in control solution (for n = 18). Note that the points in both graphs cluster around the dashed line, which represents equality. The continuous line represents the linear fit to the data.
