EEG / International 10–20 System

International 10–20 System

The 10–20 system or International 10–20 system is an internationally recognized method to describe and apply the location of scalp electrodes in the context of an EEG exam, polysomnograph sleep study, or voluntary lab research. This method was developed to maintain standardized testing methods ensuring that a subject’s study outcomes (clinical or research) could be compiled, reproduced, and effectively analyzed and compared using the scientific method. The system is based on the relationship between the location of an electrode and the underlying area of the brain, specifically the cerebral cortex.

Our headcaps are made in accordance with the International 10-20 System.

Spes Medica offers the possibility to customize the electrode layout up to a 128 channels application.
