In which electrode positions is LAMBDA typically found?

The LAMBDA wave is typically associated with the occipital region of the brain, which is closely related to visual processing. When considering electrode positions, the occipital electrode sites are placed at O1 and O2 on the 10-20 EEG system. These sites are ideally suited for detecting LAMBDA because the wave is prominent when the subject is visually alert and involved in visual tasks. As such, the placement of electrodes at the occipital positions allows for the best detection of this specific wave pattern in EEG recordings.
