At an equivalent paper speed of 15mm/sec, how long does one page of printed EEG represent?

• A. 10 seconds
• B. 20 seconds
• C. 5 seconds
• D. 15 seconds

Answer: (B)

At a paper speed of 15 mm/sec, one must consider how many millimeters are typically represented by one full page of an EEG. In standard EEG practice, one page often represents 300 mm of data. To calculate the duration that this 300 mm corresponds to at a speed of 15 mm/sec, we can use the formula: Time (seconds) = Distance (mm) / Speed (mm/sec). Plugging in the values, we have: Time (seconds) = 300 mm / 15 mm/sec = 20 seconds. Thus, at a paper speed of 15 mm/sec, one page of printed EEG represents 20 seconds of brain activity. This calculation aligns with standard EEG practices, where recording lengths and speeds are predetermined based on the clinical need to visualize brain activity over specific time frames.
