What is a key characteristic of electrodes when exposed to radio frequency energy?

When electrodes are exposed to radio frequency energy, they can behave like an antenna. This is because antennas are designed to capture and transmit electromagnetic waves, and the characteristics of the electrodes can allow them to pick up this radio frequency energy. When placed in a field of electromagnetic radiation, electrodes can resonate and capture some of that energy, which is similar to how antennas function in terms of frequency and energy reception.

This behavior is particularly important in the context of neurophysiological monitoring during surgery because it can lead to unintended interference with the recorded signals. Understanding this property helps clinicians take precautions against potential artifacts in the data, ensuring more accurate monitoring during procedures. Recognizing how electrodes can act as antennas emphasizes the need for proper placement and shielding when using neurophysiological monitoring equipment in environments where radio frequency energy is present.
