Comparison of amplifier settings for intraoperative and postoperative recording sessions.

	OR	INS
Input impedance	>100 MOhm	1 MOhm
Range	−250 mV–250 mV	−10 V–10 V
Filters used	0.5–2000 Hz	0.5–100 Hz
Sampling Rate	4800 Hz	422 Hz
Noise Floor	<0.3 µV RMS (0.1–10 Hz)	Min signal to detect 1 μV RMS differential with noise floor <0.3 µV RMS

OR, operating room. INS, implantable neurostimulator. MOhm, megaohm. RMS, root mean square.
