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
