Is the animal restrained?
yes

What kind of electrophysiological measurements
are you making?


intracellular recordings. I'm concerned with the shielding actually.

Electrode/skin impedances are fairly low, although the preamp gain is
substantial for EEG signals with surface electrodes. If you're doing
intracellular recordings, the very high impedances will present a
definite problem with electrical radiation and magnetically-induced
currents. Implanted depth electrodes would fall nearer to the surface
electrode case.
