Abstract
A system and method for monitoring nerve activity in a subject. The system includes a plurality of electrodes placed in proximity to skin of the subject, an amplifier electrically connected to the electrodes and configured to generate a plurality of amplified signals corresponding to electrical signals received from the subject through the electrodes, and a signal processor. The signal processor applies a high-pass filter to the amplified signals to generate filtered signals from the amplified signals, identifies autonomic nerve activity in the plurality of filtered signals; and generates an output signal corresponding to the filtered signals. The high-pass filter attenuates a plurality of the amplified signals having frequencies that correspond to heart muscle activity during a heartbeat.
