Which of the following could explain this? - Brachial plexus Assume your impedances for two recording electrodes are 5.1 kΩ and 2.1 kΩ. What should you do to reduce background noise and improve responses? - Equalize electrode impedances During a median nerve preoperative study, a patient has discomfort at the wrist.
