  • Can I use a laser that has no analog control and only TTL? Sort of. Zapit has a TTL signal signal on AO3 that is used to drive an optional masking LED. You could connect this to your laser and it will drive it. However you get no rapid power control, so you have to use the same number of points in every trial and you can not ramp down power at the end of the stimulus. The latter is a problem, because it will generate rebound artifacts when the stimulation ends.

  • Which wavelengths does the system work with? Any, but if you are using far red .
