Table 1. Neuronal firing pattern observed for various kinds of stimulation pattern.

INPUT TYPE	Input Magnitude	INITIAL atp	Behavior
Continuous	Is = 0.1 mA/cm2,	[ATP]0 = 20 µM	Continuous Firing
1 s Pulse	Is = 0.1 mA/cm2,	[ATP]0 = 20 µM	Return to resting state
Continuous, subthreshold	Is = 0.05 mA/cm2	[ATP]0 = 20 µM	Firing with Initial Pause
1 s Pulse	Is = 0.1 mA/cm2	[ATP]0 = 5 µM	Bursting
Continuous, Vessel Oscillation	Is = 0.1 mA/cm2
2) 0.2 Hz, Maximum Radius 30 µm for 0.5 s	[ATP]0 = 5 µM	Forced Vessel Oscillations
