What is the distance from Fp2 to F8?

The distance from the Fp2 electrode to the F8 electrode is typically measured based on standardized positions in a 10-20 EEG system. According to the international 10-20 system for electrode placement, the distance between Fp2 and F8 is approximately 5.0 cm. This measurement is crucial for accurate electrode placement during an EEG, as precise distances ensure the reliability of the data collected and are fundamental to the interpretation of the results.

This distance reflects the standardized measurements used in clinical practice and highlights the importance of maintaining consistency in electrode positioning to achieve valid and reliable readings. Understanding the distances between these electrodes is essential for sleep technicians when performing EEGs, as it directly influences the functionality and accuracy of the recordings.
