Comparison of Expanded Versions of Model 1 (Fig. 11)

Model		Relative log(Maximum likelihood)		AIC rank		Number of parameters
1-4		+45.4		1		13
1-3		+40.0		2		11
1-2		+5.4		3		10
1		0		4		8

Single channel currents activated by 5, 10, 15, 20, 30, and 50 μM ATP were used for the calculations of maximal likelihoods and AIC ranks. All data were from the same patch. The lowest number of AIC rank is considered best. Detailed balance constraint was applied in the loop of Models 1-3 and 1-4. Missed events were corrected by imposing a dead time of 0.05 ms. (Models 1-2, 1-3, and 1-4 are from Fig. 13.)
