	Recorded with normal pipette solution				Recorded with SB202190 in pipette
	Tonic firing	Initial bursting	P	Delayed firing	Single spike	Tonic firing	Initial bursting	P
Values are mean ± SEM. P value in the column: tonic vs. initial bursting neurons recorded with the same pipette solution. P value in parentheses: recorded with vs. without SB202190 in pipette solution for the same type of neurons. *Student's t test, †Wilcoxon rank-sum test. C_m, membrane capacitance; R_in, input resistance; RMP, resting membrane potential; CT, current threshold for action potential.
