Dear colleague,

I would like to stimulate my recorded cell (whole-cell, pyramidal cells in hippocampus) with a pulse train of light during 600 ms. In the middle of those pulses of light, I would like to stimulate electrically the axons (0.1 ms, 1 pulse). How can we "superimposed " the two stimulations with clampex 10 ? For now I found how to build the protocole with one stim after the other. But I would like to stimulate electrically while the pulse of light is ON.

My electric stimulator is branched on the Out#0 and the LED is branched on the Out#1 of a Digidata 1500A.
