Parameter*	K+ current	Rb+ current	P‡
Mean current at +60 mV (pA)	0.56 ± 0.04 (n = 6)	0.41 ± 0.03 (n = 6)	0.02
τO, brief (ms)	0.9 ± 0.01 (n = 3)	1.1 ± 0.2 (n = 4)	0.4
τO, long (ms)	4.4 ± 0.8 (n = 3)	7.1 ± 0.5 (n = 4)	0.03
WO, brief	0.82 ± 0.06 (n = 3)	0.64 ± 0.03 (n = 4)	0.03
WO, long	0.18 ± 0.05 (n = 3)	0.38 ± 0.03 (n = 4)	0.02

^*τ_O is the mean open duration and W_O is the relative weight.
