Review of 10/20 system of electrode placement for EEG recording. Polysomnography. Sleep Study. Epilepsy Diagnosis
An internationally recognised method that allows EEG electrode placement to be standardised.
Montage is a collection of derivations for multiple channels recorded simultaneously and arranged in a specific order 
• Scalp electrodes applied according to the International 10-20 System. The advantages of this system is as follows: 
• Ensures inter‐electrode spacing is equal
• Electrode placements proportional to skull size & shape
Basics of International 10-20 System: 
• Covers all brain regions: F= Frontal; T= Temporal; P = Parietal; O = Occipital
• Numbering system: Odd = left side, Even = right side, Z = midline
