Compound action potentials elicited by varying pulse durations. The CAPs evoked by the laser change with different pulse durations. At the shortest pulse durations, the CAP is primarily composed of one negative peak (N1) and one positive peak (P1). As the pulse durations increase, there is a secondary peak that increases in amplitude. These CAPs were measured from the same animal. The amount of time between the onset of data acquisition and onset of CAP decreases as the pulse duration increases due to the data acquisition trigger from the laser.
