Certain embodiments described herein relate to a system for use in analyzing neural activity of nerves surrounding a biological lumen. The system includes a probe body, electrodes, a stimulator, and an amplifier. The stimulator delivers electrical stimulation via a first pair of the electrodes, supported by the probe body, to test for an evoked neural response by nerves surrounding the biological lumen. The amplifier includes a pair of input terminals, an output terminal, and a ground reference terminal. A second pair of the electrodes is electrically coupled to the pair of input terminals of the amplifier, to thereby enable the amplifier to produce the sensed signal indicative of the evoked neural response. A remaining one of the electrodes, which is not included in the first and the second pairs of the electrodes, is electrically coupled to the ground reference terminal of the amplifier.
