Primary standardized method for applying patch Electrodes for EEG
- letter corresponds to Lobe/brain region it is reading from:
- Prefrontal(Fp)
- Frontal(F)
- Temporal(T)
- Parietal(P)
- Occipital (O)
- Central (C)
- there is no “central lobe”; due to their placement, and depending on the individual, the “C” electrodes can exhibit/represent EEG activity more typical of frontal, temporal, and some parietal-occipital activity, and are always utilized in polysomnography sleep studies for the purpose of determining stages of sleep. - wikipedia
- also a Z site, refers to electrode placed on the midline/sagittal plane of the skull, (FpZ, Fz, Cz, Oz)
- numbers corresp to side
- even numbers on left on right side, odd on left
