In an EEG montage, which electrode corresponds to location F4?

In an EEG montage, the electrode labeled F4 corresponds to the frontal lobe. The nomenclature used in EEG electrode placement is based on the International 10-20 system, which is designed to provide consistent and systematic electrode positioning on the scalp.

In this system, the letter "F" stands for "frontal," indicating that the electrode is positioned over the frontal lobe region of the brain. The number "4" denotes a specific placement in relation to the midline and other associated electrodes. Therefore, F4 is specifically located over the right frontal hemisphere, making it a key point for monitoring brain activity in that area.

Understanding the layout of the EEG electrode locations is essential for interpreting the corresponding brain wave patterns, which can provide valuable insight into neurological function or dysfunction.
