The Othmer Method (Requires NeuroAmp® and Cygnet®)

Good technology is only one component of effective neurofeedback. Even more important is an effective treatment method. In comparison: For effective driving you need a good road map or a good GPS. Over the last 25 years the Othmers have developed a technique which is considered as very efficient. Development of this method occurred similarly to the development of pharmaceuticals: Based on proven neurofeedback protocols (such as the classical beta-SMR training) the feedback parameters were optimized and further developed purely based on the effect on the client, accompanied by a continuous development and improvement of neurofeedback hardware and software. This lead to the fact that now signals are included in the training which were until now always filtered out as "Baseline Wander", namely the very low frequencies (ILF = Infra Low Frequeny). Only the SCP training method (Slow Cortical Potentials) also works with this frequency domain.

The Othmer method today is a combination of three powerful components:

  1. Classic frequency band training: The classic band training is clearly part of Cygnet and the Othmer method. Even if we work at very low frequencies, we use the dynamics of the feedback methods; in addition to that there are also many individual inhibits at work, even up to 40Hz.
  2. ILF training: The effectiveness of the work in the field of Slow Cortical Potentials is now clearly established due to the many studies that have taken place in Germany in the recent years. We have empirically entered into this frequency range in the last years and have continually optimized the protocols.
  3. Bipolar training: Empirical studies have clearly shown that feedback to the brain on how the two regions work relatively to each other, is much more efficient than displaying only the activity of a single one. Most Othmer method protocols are based on bipolar placements. Note: Nevertheless, usually one EEG channel is sufficient, which simplifies the practical work very much.

NeuroAmp and Cygnet

Do you remember what airplane cockpits used to look like? With hundreds of buttons, levers and instruments? Imagine a car would look like that and what you could all adjust and optimize! For example, the cylinder head temperature, the fuel-air mixture, the ignition timing, the fuel pump pressure, chassis stiffness, brake behaviour ... A modern car has three controls - steering wheel, accelerator, and brake. And of course, a few peripheral controls - not that the auto industry doesn´t think you could adjust the ignition timing even more optimal - but a modern car is designed so that you can focus on the growing demands of road traffic to safely and efficiently reach your destination.
This is exactly the philosophy of Cygnet - a neurofeedback system, where, in the background, hundreds of parameters are set in an optimum way for you, as a result of our twenty-five years of experience in the development and clinical use of neurofeedback systems. This enables you to focus on your clients and effectively obtain the desired results

Neurofeedback at very low frequencies (ILF = Infra-Low Frequencies) proved to be very effective. Therefore, Cygnet has been equipped with an ILF-Module (since version, see picture) for training in this "frequency" band. Calculation of rewards and inhibits is different from the classical frequency band training. The whole transfer function between electrodes and feedback has been optimized and tweaked for maximum efficacy in EEG Info's own clinical research and in its development labs over the course of two years. In the ILF module there is no need for an artifact correction (automated), nor for the % success sliders. The clinician now just controls the reward-"frequency" by means of the logarithmic milli-Hertz Slider. All other technical decisions are being dealt with by the software. Note that the very low frequency contents of the signal are not being shown in the 'oscilloscope' of Cygnet- here, an internal high-pass filter is applied for display purposes.

The EEG NeuroAmp does not even have an on / off switch. But a clear and easy to read display for the electrode impedance, which allows the safe and correct placement of the electrodes. The employed broadband technology can be compared to a scale that you can weigh an elephant with the precision of a postage scale with.
NeuroAmp and Cygnet, including the feedback games, are approved as a medical device both in the EC (CE) and in USA (FDA) and thus meet the highest standards of quality. To our complete sets

For Cygnet, we have developed a variety of appealing feedback games. So for every client, the optimal feedback can be selected.

In developing the protocols and also the equipment and software we have constantly used the increasingly powerful computer technology. On the one hand for ever more sophisticated signal processing, on the other hand for better multi-dimensional feedback. Thus, we can now control up to twelve elements of a feedback game independently from each other with selected properties of the EEG.  

Note on approvals:

Given the high efficacy of neurofeedback and its application in therapy there is no doubt that this technology requires approval as medical device. In Europe, NeuroAmp and Cygnet are approved as medical product "for training the central nervous system to improve its capacity for self-regulation". In the U.S. there is only one category for biofeedback devices with the intended use: "for biofeedback and relaxation purposes". The Othmer Method, which EEG Info is all about, is entirely based on this intended use (see more details on that here). Therefore, indication-specific approvals are not required.

Structured Approach

The process of developing training protocols, equipment and software always aims at a single goal: To ensure maximum efficiency on the one hand and safe application on the other. In addition to an easy-to-use system, we have written down the training method in a structured and systematic manner in the Protocol Guide.

And what about QEEG?

When Hans Berger discovered the EEG (ElectroEnzephaloGramm) in the 20s of the last century, the hypothesis was not far that these brainwaves could be used for diagnosis of mental health issues. Then with the advances of computer technology more sophisticated analysis and especially the creation of normative databases became possible. We are of the opinion that only the analysis of event related potentials allow a statistically signifikant diagnosis. This is why we, in cooperation with the HBimed AG, that has developed the largest normative database containing such data, are developing a methodology that will allow the selection of appropriate neurofeedback protocols with even more precision.


In EEG Info we have combined top expertise from many disciplines:
- Clinical research and trials
- Theoretical investigations, scientific work

- Develpoment, manufacturing, qualification, testing of approved medical devices
- Contemporary feedback games
- Moderrn software kernel for real time processing

We also want to mention our large customer base. The feedback it provides us also helps to improve and expand the product continuously.
