[Neuroscience] Minimizing stimulus artifacts

[Bill]

Hey,

Another dull question: I need tips of minimizing stimulus artifacts. I
know the best way is to use low stimulus amplitudes/durations and have
the two poles of your stim. electrode very close together, but that is
not possible.

I am told that using a biphasic stimulating paradigm (i.e. the pulse
changes polarity half way through) is helpful; though I can't find one
to test that theory out. Has anyone tried that?

Are there any other tips?

(I'm running a Grass S88 with it's corresponding stimulus isolator,
square pulse, constant voltage).
