Based on my reading of numerous papers, I have created a mental picture of the experimental setup used for electrophysiological recordings of the A cells excited by ultrasound stimulus. I need to check my understanding though.
Would you have, or would you be able to obtain any pictures of experiments?
I am specifically interested in close ups that may show most of the following together: the sound source, the microphone, the moth, the mounting plate, the electrodes.
Thank you
A cells are mostly recorded extracellulary, so one uses a hook electrode. Imaging a string, hook the electrode on to that, now on one end of the string is a moth body on the other end is your loudspeaker as sound source. One normally has measured the distance between the mounting plate and sound source, so that during the actual nerve recording no microphone obscures the experiment.
Are you in contact with Lutz Thilo Wasserthal? He did some experiments during the 1980s and 1990s that might fit in with what you are looking for.
I have done (and still do) these recordings all the time -- if you still need such illustrations and photos, I'm happy to help.

Hi Jeff,
I am still in need of illustrations and pictures of these experiments.
Would you mind sharing with me what auditory stimulation method you use at the moment? Would there be any deviation from the method you previously used in the papers you co-authored about the spiking of the moth's A* cells?
Regards
