Measured activity between two electrode pairs is referred to as

• A. Unipolar
• B. Bipolar
• C. Multipolar
• D. Monopolar

Answer: (B)

Bipolar recording is the measurement between two closely spaced electrodes with differential amplification. This setup captures the difference in voltage between the two points, emphasizing local electrical activity while canceling out signals that are common to both electrodes, which reduces far-field noise. That contrasts with unipolar (monopolar) recording, where the active electrode is compared to a distant reference and is more susceptible to distant signals. Multipolar involves more than two electrodes to sample activity from multiple directions, rather than a simple two-electrode differential pair. So, measuring activity between two electrode pairs corresponds to a bipolar configuration.
