The experiments are identified in the column 1 and match Figs. 5 and 7, A, B, C, D, E, and F, along with H and T, which match Figs. 4 and 6. Total numbers of excitatory postsynaptic currents (EPSCs) are given, as well as the number of monophasic and multiphasic EPSCs. Kernel decay time is time from 90% to 10% of maximum value, as in Fig. 3. The K+ concentration in the bath solution is in column 3. Tetrodotoxin (TTX) was present in 5 experiments in column 4. Experiments B and H were used in previous publications (6, 12).
