RECORDABLE AREA / 10%-SYSTEM

10%-Electrode System and Electrode Position Nomenclature of the American Electroencephalographic Society

Montage No. 1

mostly equidistant, inter electrode distance 28 bis 38 mm (given a head circumference of 58 cm).

This graph shows all 10% electrode positions which can be mounted in a subtemporal cap. The inner circle encompasses the area of the int. 10/20-system, the outer circle encompasses another 10% from the canthi to the inion.

A cap with 74 adaptors mounted like this enables to work with the defined 10% positions in a great variety of investigations.

The differences to the german electrode nomenclature is demonstrated on the next page. After that the american names will be used throughout this booklet.
