Figure 4.
Single GABAA and glycine channels from presynaptic membrane. (A–D) Sample records and amplitude histograms for patches from the indicated ages exposed to 10 μM GABA or glycine. Histograms were fitted with sums of four to five Gaussian curves. Means of component were used to estimate channel chord conductance (given in pS above each peak), assuming a reversal potential of 0 mV.
