Which electrode placement is associated with the frontal lobe?

The electrode placement associated with the frontal lobe is F4. The naming convention for electrode placements in electroencephalography (EEG) is based on the International 10-20 system, which defines specific locations on the scalp corresponding to underlying brain regions. The "F" in F4 indicates that this electrode is positioned over the frontal lobe.

F4 is located on the right side of the scalp, generally over the area corresponding to the right frontal cortex. This region plays a significant role in various functions, including reasoning, motor function, emotion, and language.

In contrast, T3 is related to the temporal lobe, Pz corresponds to the parietal lobe, and O2 pertains to the occipital lobe. Each of these electrodes focuses on different brain regions and their associated functions, further emphasizing that F4 is indeed the correct choice for representing the frontal lobe.
