The BrainMaster Discovery 24 system features 24 channels for recording EEG signals. 22 of these channels are available via a standard electrode cap (http://brainmaster.com/wp-content/uploads/2020/07/5Wh6F7KC1R1121.mp4), complemented by two differential input channels with separate references. This configuration enables the recording of a wide range of EEG and related potentials.

The system is equipped with low-noise, DC-sensitive amplifier technology and 24-bit analog-to-digital converters, offering a sampling rate of 1024 measurements per second on all channels. The amplifier covers a frequency range from DC (0 Hz) to 80 Hz. This makes the device suitable for use in research, clinical settings, laboratories, and supervised home training.

Data is transferred via a USB interface that is optically and magnetically isolated, ensuring secure and stable signal transmission. The device is fully USB-powered, eliminating the need for batteries and ensuring electrical safety.

Thanks to its lightweight and portable design, the Discovery 24 system can also be used in mobile applications together with laptop computers.

Thank you very much for this seminar

Dagmar Richter, St. Vinzenz Hospital Department of Occupational Therapy

Dear Ms. Branga,

We would like to thank you again today for the fantastic and informative internship day with you. We believe we will benefit greatly from it in our work in the coming weeks and months. Your expertise and enthusiasm for the project were truly contagious and enriching for us.

We are already looking forward to a sequel.

All the best and warm greetings from Bergisch Gladbach

Hanna Gjakonovski and Elisabeth Völker

I wanted to briefly describe my experiences after about 3.5 years of neurofeedback with the Thomas Feiner Institute for EEG – Neurofeedback.

The beginning is quickly told. I was very surprised by the competent, professional training I received at the institute. Based on these experiences, I then purchased my first software and hardware from the company Neurofeedback-Partner.

Mr. Feiner's team was there to support me during my first steps in neurofeedback (and the next steps as well), with professional competence and a friendly attitude. They were there almost around the clock. Now I'm a bit more confident, they will always be my contact, as their expertise and the comprehensive service package (see website) are simply perfect.

I would like to take this opportunity to thank Mr. Feiner and his team.

Your lecturer, Ruth Kreider, does a fantastic job, sets the right priorities, and I learned a great deal.

Dr. Karl-Wilhelm Jung, Head of Cardiovascular Medicine Practice, Offenburg

I just participated in the first module of IFEN (Thomas Feiner) at the end of June.

This training was held by occupational therapist Normen Schack in his practice in Hanover.

I went there on the recommendation of a colleague who had already participated in this training course.

Although I have no basis for comparison, I can only recommend this to you. I was very satisfied and gained a lot from the training.

L. Hilmes in a forum for occupational therapists

.... and to all of the BrainMaster and Stress Therapy crew.

This workshop was the best ever! There was so much useful information and all of the speakers and presentations were excellent. If you have never been to a workshop you do not know what you are missing. I had the honor of sitting and working with Rob Longo. Very exciting. Thank you all to those that attended and the new friends I have made.

Bill Brubaker

Our practice has been using the Brainmaster 4x4 channel for three years. We're very satisfied with it. There have rarely been any problems with the device or the program, and when there have been, I've always received immediate, quick, and helpful telephone support from Thomas Feiner, ensuring that there have been no missed sessions due to technical issues.

The service is very good and the webinars are also helpful.

In addition, there is a constant informative exchange with Thomas Feiner and the neurofeedback therapists trained at IFEN through the forum he leads.

Thank you for that.

Julia Reinsberg, senior occupational therapist at Fischer Practice in Hamburg

I've been working with NFB for over three years now—sometimes more, sometimes less, but for the last two years almost daily. I've familiarized myself with the various manufacturers and suppliers.

I then opted for the Brainmaster 4x4. I haven't regretted this decision once. I've repeatedly looked at other devices and methods, which was always exciting and educational, but I wouldn't change anything. Four weeks ago, I decided to order the Discovery and the Avatar. I believe in the effectiveness and possibilities of NFB, also because I've achieved good results in my practice for dyslexia, dyscalculia, and ADHD. Treating adults as an accompaniment to and supplement to psychotherapeutic intervention, whether in the area of burnout, depression, stress management, sleep disorders, or migraines, is fantastic. The possibility of incorporating a QEEG and thus achieving even more precise results seems to me to justify the investment, because I get fair value for money with the Brainmaster devices—a truly unique opportunity to help people alleviate their suffering as often as possible. I've attended several training courses and seminars.

I stand by the philosophy and the way Thomas Feiner carries out his work; I find his commitment and his work meaningful and committed in a way I have never experienced before.

WHY ARE CE AND MDR IMPORTANT FOR BRAINMASTER USERS?
