🔍 Can you identify the source of the noise on this image of MEP data? 💡 Notice that if you count the number of noise “spikes” seen in this image you’ll see ~12 spikes in 10 divisions. Some quick math (12 spikes x 10 divisions) tells us the cycles per second = 120Hz which is a harmonic of 60 cycle noise from surrounding equipment.
