The international 10-20 System of Sensor Positions (according to Herbert Jasper, 1958)
Download

Acrobat Reader
The international 10-20-System is the system of electrode/sensor positions on the scalp. In this standard system, used with Neurofeedback, 19+2 sensor positions and their names are defined. A more detailed system with 61 sensor positions exists as well, but for the most training purposes the system with 19+2 positions is sufficient.

This table form is used be filled with Z-score values derived in an assessment. In this matrix form the form serves as supplementary aid to BrainMaps to give an overview simultaneously over significant Z-score values of a frequency band (in a column) as well as over a particular electrode site (in a row). This table form can support the training planing. The three most right columns can be used to be filled with significant Z-score values of coherences.

 Montage Types


Referential, Bipolar and Laplacian Montage:

Placing the electrodes/sensors, three basic montage types can be distinguished: The referential, the bipolar and the Laplacian Montage Type. The later one is named after the french mathematician Pierre-Simon Laplace who gave the name for the mathematical operation called the Laplace transformation.
The referential and the bipolar montages are 2-point-montages (1 active and 1 referential electrode) per 1-channel evaluation, whereas the Laplacian montage is a 5-point-montage (1 active and 4 referential electrodes around) for a 1-channel-evaluation.

More commonly used in daily practice are referential and bipolar montages/derivations:

Neurofeedback - Referential and bipolar Montage




A 1-channel referential or bipolar derivation consists of 3 cables (2 channels = 5 cables) , one for the active electrode, one for the reference electrode and one for the ground (GND) of the electronic unit.

At a referential montage the reference electrode is (virtually) located on a fixed potential, symbolized in the image above by the yellow flag on the mainland and the active electrode symbolized by the blue flag. This way the blue flag indicates the wave movements in reference to the mainland, but also the movements of the tides in reference to the mainland.

At a bipolar montage both electrodes are located on active ground, symbolized by the green and red flag in the image above. Thus the bipolar montage indicates the wave movements but the tide movements (long distance effect) are eliminated - i.e. are not part of the measurement.






 Z-score Training


Z-Score Statistics:

The z-score value is a term from statistics and expresses how far a measured value (in Neurofeedback e.g.: amplitude, relative amplitude or coherence of a frequency band) of a test person is apart from the statistical average value of a reference group.

A z-score value of 0.0 indicates that the measured value of the test person is the same as the median of the reference group (50% of that reference group have a higher and 50% have a lower value). A value of +1.0 indicates that the measured value is greater than the average of the reference group, namely that (in the mathematical ideal case) 84.1% of persons of the reference group have a lower value (accordingly with a z-Score value +2.0 = 97.7%; 3.0 = 99.9%). At negative z-score values, the measured value of the test person is lower than the corresponding average of the reference group.

A z-score training concept assumes that with present deficits in health or performance the state can be improved towards "normalcy" by training toward smaller z-score values (ideally, against 0.0).
