Neurofeedback is so fascinating, is`nt it? But when you are not yet familiar with it is sometimes complicated. With our Neurofeedback ABC on Instagram and Facebook we introduce to you every week neurofeedback related terms. Compact and understandable. To learn and share with the #neurofeedbackabc and #beemedic. And if you are not on social media we will keep you up to date here at our blog.


“In a multicentre observational study 97% of 196 children and adolescents who received 30 sessions of ILF neurofeedback over a 15-week period reported a clear improvement in symptoms.”

About five percent of school-age children suffer from ADHD. But it does not only affect children. Many adults continue to experience additional problems such as anxiety or sleep disorders. For ADHD ILF Neurofeedback can be an effective tool to:

> Improve concentration
> Encourage relaxed attention
> Increase frustration tolerance
> Improve the ability to switch between different states of attention
> Improve sleep
> Relax the school and homework situation
> Reduce medication doses if necessary

ILF Neurofeedback also appeals to young patients in particular because of the broad range of feedback animations we have, which resemble a computer game


B - Biofeedback
“Biofeedback is a term used in behavioral medicine to describe procedures that enable us to make unconscious processes of our body and psyche perceptible and thus influence them.”

People can learn almost anything. The prerequisite is that there is a feedback between what is wanted and what is achieved. For example, we cannot learn to ride a bicycle if we do not feel any incline. Most of the functions of our body and psyche, on the other hand, we cannot directly perceive or consciously influence. They are controlled automatically, such as blood pressure, skin conductance, body temperature and many others. If such a function does not work properly anymore or even fails completely, there is hardly any possibility to train it, because there is no direct influence. This is where biofeedback comes into play.

Biofeedback can be combined in many ways with various methods of psycho- and physiotherapy. Just by measuring body signals, such as heart rate, muscle tension, breathing, skin conductance, the patient can be shown very well how the body reacts to certain topics, thoughts, inner images or suggestions.


C - Courses
We emphasise the importance of high-quality and well-founded neurofeedback training. Our courses are therefore exclusively aimed at mental health professionals and have a high proportion of practical training and self experience.

Excellent neurofeedback education has always been very important to us. So important that we offer our courses and those of our training partners with an own product brand: EEG Info Europe. 

There, mental health professionals will find basic courses as well as a wide range of advanced and indication-specific courses. And depending on your individual needs, you can attend live online or increasingly on-site courses again.

Our instructors are true neurofeedback enthusiasts. All of them are experts who work successfully with neurofeedback themselves on a daily basis in clinics and practices. 

Furthermore, our courses are characterized by

> Intensive practical and self-experience
> Excellent course organization
> Attractive venues
> Wide range of online courses
> Course equipment - during the training we provide you with high quality neurofeedback equipment
> Courses in several languages throughout Europe
> Indication specific courses for advanced users e.g. ADHD, PTSD, pain, peak performance, burnout
> Full technical support


D - Dreamscapes
Dreamscapes© is a collection of 27 feedback animations for neurofeedback with our Cygnet© neurofeedback software. It includes landscape animations as well as creativity and thinking games and puzzles for an individual neurofeedback experience.

Not all neurofeedback is the same. 

Feedback animations play a central role in neurofeedback. They visualize what is to be reflected back to the brain. 

The first neurofeedback animations were very simple. Mostly they were bars that changed their height depending on the EEG frequency. And even today - more than 30 years later - very simple animations are still common in some procedures, where for example objects simply move up and down. 

However, the technical possibilities are far greater. Feedback games such as Dreamscapes©, InnerTube© or Tropical Heat© make it possible to experience animations similar to a video game. With ILF neurofeedback, up to 14 parameters are sometimes hidden in an animation - from color nuances that change subtly to the speed and movement of objects in the foreground and background to the brightness. In addition, the Cygnet© neurofeedback software offers a particularly wide range of different animations, which allows an individual adaptation to the patient. This promotes motivation and anticipation of the neurofeedback sessions, the therapy is diverse and, last but not least, patients can actively participate in therapy decisions. 


E - Enthusiastic
Neurofeedback enthuses patients and therapists! Neurofeedback is not only effective and painless, but also fun and it brings ease into everyday therapy.

Modern Neurofeedback is user-friendly and highly effective. 

Our systems are easy to use and allow therapists to concentrate on what matters most - their patients and the therapeutic work. Neurofeedback sessions can be a way to bring more lightness and ease into the therapeutic daily work. 

But not only therapists enjoy the neurofeedback sessions! The rapid treatment success and symptom improvements motivate patients and therapists. 

During the session the patient can lean back and relax while the brain performs neurofeedback automatically and without effort. And due to our wide range of different feedback animations, the neurofeedback sessions can be individually adjusted to the patient which makes the therapy even more attractive. This makes patients look forward to their neurofeedback session! 


F - Frequency
Frequency is measured in Hz (Hertz). The frequency describes how fast a regular process repeats itself in a certain amount of time. We also measure brain waves in Hz and we know that neurofeedback with particularly slow frequencies down to 0.0001 Hz is extremely effective.

What was that about frequencies and amplitudes...? Don't worry! You don't have to be a neuroscientist or a physicist to use modern and effective neurofeedback.

But to understand where neurofeedback actually comes in, we need to understand that electrical signals are continuously produced by the nerve cells in the brain. Whenever nerve cells join and oscillate together, we recognise rhythmic patterns, the so-called brain waves. 

The psychiatrist and neurologist Hans Berger discovered this a 100 years ago and invented the electroencephalogram (EEG) to record brain waves. In the meantime, we know that there is a wide range of brain waves, from very slow ones over several hours or even days to over 100 oscillations per second, which are also summarised in the so-called frequency bands. And that these are related to certain states of consciousness and functions. Modern EEG amplifiers allow us to measure the different frequencies precisely. And with neurofeedback we can learn to influence them.


G - Growing Evidence
A randomized controlled trial from the year 2020 has shown that just one session of ILF neurofeedback leads to significant changes in the brain’s connectivity.

In the study “"Modulation of Intrinsic Brain Connectivity by Implicit Electroencephalographic Neurofeedback" (2020), Dobrushina and colleagues have been able to show that ILF Neurofeedback modulates significant changes in brain connectivity.
The 52 healthy subjects completed a 30-minute ILF Neurofeedback session (electrode position: T4/P4) in a double-blind, controlled experimental design. Before and after the Neurofeedback session, the activity of neuronal networks in the brain was recorded in all subjects using functional magnetic resonance imaging (fMRI) at rest showing significant changes in the brain’s activity and connectivity post neurofeedback.
Evidence like this is important to support the clinical effects we see in neurofeedback in a variety of indications. But what exactly do we mean when we speak of evidence? “Evidence based“ means that a method is proven to be effective by scientific outcomes.
Neurofeedback – which has been scientifically examined for more than 35 years now – shows growing evidence with more than 2.000 published studies. (Pubmed, 2021)

H - High Performance
Neurofeedback improves the self regulation of the brain. As so called high or peak performance training it aims to improve performance in situations where you are required to give your best. 

Usually, the main focus of Neurofeedback is the therapeutic treatment. But Neurofeedback can also be used to enhance performance and this application area has gained more importance during the last years.

High or peak performance training can be especially useful to improve performance in sports, leadership situations or as a musician. Studies have shown that Neurofeedback training can improve executive functions which can help deliver the best performance in special situations and under pressure.


I - ILF Neurofeedback
Infra Low Frequency (ILF) Neurofeedback works with very low frequencies of 0.1 to 0.0001 Hz. It allows us to work with the best individual frequency for each client.

The Othmers worked with the beta/SMR training first, but they soon developed the first improvement in the procedure. They decided to no longer simply reward exceeding a single threshold level, but to work with the dynamic of the reward frequency band. The clients were now given feedback of their brain activity from an animation in which a bar moved up or down. The bar represents the proportion of Beta/SMR frequencies in the Frequency Bands recorded from the EEG.
Working with dynamic feedback has been made possible by advances in computer technology, which, moreover, could increasingly reflect the EEG signals in ‘real time’, with almost no  delay. Using the dynamic of reward frequency bands as a feedback signal marked the first of many subsequent shifts away from the initial explanatory model because this neurofeedback was no longer based on operant conditioning.
If you are curious to learn more, you can read our blog article or download the whitepaper about the development of the Othmer method.


J - Joy
Neurofeedback is fun and motivating because it doesn't really feel like therapy.

Children and adolescents especially look forward to their neurofeedback training. Through the feedback animations, some of which are similar to a computer game, they find easy access to the therapy. They enjoy neurofeedback and often can hardly wait to go to the next session again.

But not only young patients can get enthusiastic about neurofeedback. Also very performance-oriented adults quickly feel comfortable with neurofeedback since the focus is not on problems or diagnoses. The brain performs neurofeedback automatically and without effort. It is a relaxing, less stressful therapy situation. This is good for patients and equally for therapists.


K - Key technology
Neurofeedback is a key technology in the field of mental health.

The World Health Organization (WHO) defines mental health as “a state of well-being in which the individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and fruitfully and is also able to make a contribution to his or her community.”

Mental health is far more than the absence of serious long-term illness. We all have times when we feel down or stressed or frightened. Most of the time those feelings pass. But sometimes they develop into a more serious problem, which could happen to anyone of us.

Mental health is considered to be one of today’s mega-trends. No wonder – approx. 10 % of the population is suffering from mental health problems in a way that prevents them from participating in our post-industrial information-centric society.

As a result, the demand for help is rapidly increasing while the supply remains limited. As in other healthcare areas technology may be able to help close the increasing service gap.

BEE Medic is specialised in developing EEG-based technology for mental health. With our modern neurofeedback solutions selected parameters of the patient's own activity, which can normally not be perceived, are made accessible to clients via the senses, e.g. by means of an audio-visual animation. This helps to improve the self-regulation of the brain and thus many symptoms of mental illnesses.


L - Long-term
Neurofeedback therapy can help to increase patient well-being in the long term. Just a few sessions are often sufficient to achieve an improvement in symptoms.

Within the first sessions of Neurofeedback, patients usually already notice some changes. But this does not mean that the improvement is finished - also in the further progress of the therapy patients and therapists notice changes in their symptoms and everyday circumstances - sometimes even partners, parents or teachers see them more than the patients themselves. Therefore it is important, also for the relatives, to report such observations back to the neurofeedback therapist for therapy planning.

Several studies have proven that Neurofeedback can help to increase patient well-being in the long term. For instance the medical journal European Child & Adolescent Psychiatry published a study that found that children diagnosed with ADHD showed large and positive improvements after 6 months of Neurofeedback treatment. In the process their symptoms have even improved over time, without needing further Neurofeedback therapy. 
Another study examined the treatment of tinnitus through Neurofeedback. The results of this study show that the participants could significantly improve their tinnitus  handicap inventory and visual analog scale scores after 5 months of Neurofeedback treatment. 
Furthermore a study of experimental neuropsychologists at Saarland University showed that subjects of the study could improve both short-term and long-term memory after participating in Neurofeedback training compared to the control group.

It can be concluded that there is growing scientific evidence which proves that Neurofeedback can improve patients’ wellbeing not only in the short term but also in the long term. 

Details and referneces to the studies can be found in our blog.


M -  Mirror
Neurofeedback is like a mirror for our brain. Through this self-awareness, the self-regulating ability of our brain and therefore also symptoms of various conditions can be improved in the long term.

During Neurofeedback, EEG signals are derived from the surface of the head. Through the positioning of the electrodes and the feedback parameters, based on the symptoms of the patient, it can be determined which range of neuronal activity is presented to the brain visually, auditorily and tactilely.

The brain uses those reported signals like a mirror. That is because our brain constantly tries to relate impressions from the environment to itself and analyze its own influence on it. During Neurofeedback, it is important for patients to realize that their brain influences what is happening on the screen. Through this self-awareness, patients can learn to improve their self-regulation skills.

For instance, stress symptoms, sleep disorders or disturbances of the attention and concentration spectrum, which often accompany mental illness, can thereby be significantly improved.


N - NeuroAmp
The NeuroAmp EEG amplifier with the integrated Cygnet neurofeedback software  is the core of effective neurofeedback.

You don't need much for neurofeedback. Most practices today value making patients feel comfortable anyway and have already comfortable seating, monitors and a laptop. For the neurofeedback itself you need the NeuroAmp EEG amplifier. The NeuroAmp is a compact, portable device which can be easily placed on a desk or a trolley. And well... the software just runs on a laptop or PC ;)

In our EEG Info Europe courses we provide the complete hardware and software for the practicum. You will see there how easy it is to use. And of course we also equip our education partners with our systems.


O - Online Training
Our Neurofeedback courses are also offered online in an effective and educational way.

Since the beginning of the Covid-19 pandemic, a large part of our lives has been taken place online. This also applies to our courses. We offer both webinars and basic courses online - with succes! With our online courses we have already convinced numerous participants who now even want to learn only online. Surely, this is also a type question, but nevertheless online learning can be fun and effective.

Online basic courses offer you planning security. The courses can take place, completely independent of possible regional or national travel or assembly restrictions as well as quarantine requirements. You also minimize your risk of infection. 

Through user-friendly software and varied course content we make sure to offer you a pleasant course experience. Of course you can also borrow and try out a complete Neurofeedback system for free of charge for the duration of the course. 

All course dates and more information can be found on our EEG Info website

If you are interested in some course insights you can read about the personal experiences of two of our colleagues, who participated in an online basic course, on our blog.


P - Patients
Neurofeedback is suitable for all patients from young to old. Due to its playful character and various feedback animations, neurofeedback is also perfectly suited for children and adolescents.

Neurofeedback is suitable for all age groups. For instance studies show that Neurofeedback can be an effective therapy option for children and teenagers diagnosed with ADHD. Neurofeedback sessions are often not perceived as therapy in a classical way and therefore provide a pleasant experience that young patients are actually looking forward to. Neurofeedback can however raise many questions. How does it work? Is neurofeedback safe for my child? How much does neurofeedback cost and how do I know if the therapist is well trained?

We at BEE Medic know that modern, effective neurofeedback is a powerful tool and therefore only train professional users with medical background in our EEG Info Europe courses. In addition, it is of course important to us that patients are well informed before they decide on neurofeedback. So in Germany we have supported since 2011 the “Neurofeedback Netzwerk” a website which gives information about the different approaches, costs and what to look for when choosing a neurofeedback therapist.


Anyone who deals with neurofeedback will quickly stumble across the term QEEG. Why we don't like to use this term and prefer to talk about brain function analysis, we explain here.

QEEG (quantitative EEG) is a method of EEG analysis. It describes procedures where spontaneous, resting EEG activity is recorded, broken down into individual frequency ranges and then graphically displayed in the form of so-called "brain maps".

But in order to make accurate conclusions for diagnostics and therapy from the observation of brain activity the comparison with a normative database is required. Here it is essential that in addition to the self-organization processes of the brain determined by analysis of the EEG in awake resting state (“resting EEG”), also the information processing processes are analysed. These are determined from the observation of the activation of different brain regions (“evoked potentials” – ERPs) during the repeated solving of standardized tasks.

This is the reason why we prefer to talk about brain functions analysis because it is necessary to look also at the ERPs. In the field of QEEG research, we therefore work closely together with HBImed AG. They have the largest and most accurate database of self-organization and information procession processes of several thousand persons.


R - Relax
Neurofeedback is a relaxed form of therapy - for patients but also especially for therapists.

During a neurofeedback session, the focus is not on problems and diagnoses, but rather on relaxing and letting neurofeedback work on you. Patients do neurofeedback "automatically". This results in less tension and stressful situations than normal. Thus, both children and often performance-oriented adults quickly find access to neurofeedback. 
But also especially for therapists neurofeedback is a relaxed form of therapy. Neurofeedback brings ease into their everyday life and allows them to simply take a breath.


S - Self-regulation
In neurofeedback therapy, the brain learns through self-regulation to find the optimal arousal frequency for itself in order to avoid over- and under arousal and associated symptoms.

In neurofeedback the brain's ability to self-regulate is trained. During neurofeedback therapy EEG signals are derived from the surface of the head. Based on the patient's symptoms, certain frequency ranges of brain activity are measured and evaluated in order to control feedback in the form of an animation on a screen in real time. Through this continuous process patients can learn to improve their ability to self-regulate. Particularly in the case of mental illnesses, accompanying stress symptoms, sleep disorders or disturbances of the attention and concentration spectrum can often be significantly improved in this way. 

What is important to know is that there is no one optimal frequency that is the same for every patient. Instead, the optimal frequency is very individual and depends on both the person and the given situation. In ILF neurofeedback, very low frequencies are used and the therapist determines the training frequency for the neurofeedback session depending on the patient and his response.


T - Trauma
In a sample of therapy-resistant PTSD patients, neurofeedback was able to produce a significant improvement in symptoms.

Post-traumatic stress disorder (PTSD) arises as a delayed response to an threatening event that would cause deep despair in almost everyone. Typical is the repeated experience of the traumatic situation in the form of flashbacks or nightmares, the social and emotional impairment. PTSD is often accompanied by indifference towards the environment, sleep disorders and avoidance of activities that could evoke memories of the trauma. 

In a sample of therapy-resistant PTSD patients, neurofeedback was able to produce a significant improvement in symptoms. One of our research groups was successfully involved in a rather large research program with U.S. veterans five years ago. It was immediately apparent that neurofeedback has a positive influence. 

Note: If you are struggling with PTSD, please be aware that Neurofeedback is not a substitute for medical treatment and a medical diagnosis.


U - You
ILF Neurofeedback is all about you! The so-called treatment protocols are are personalised to you. Depending on the symptoms and goals of the neurofeedback therapy.

Different neurofeedback approaches are available today, differing mainly in which parameters are fed back from the EEG and how these control the feedback. It is always debated whether a "one-size-fits-all" approach, such as classical frequency band training (in which we also have our origins), or an individualized approach, such as ILF neurofeedback, in which primarily changes in patient symptoms should guide neurofeedback training, is preferable.
The first neurofeedback protocols in the 1970s were nothing more than classical frequency band training. Since this has been around for a very long time, it is also well researched. The advantage is also clear: a "one-size-fits-all" approach is quick to learn. Certain frequencies are considered good and you train to reach them.
Individual neurofeedback, such as ILF neurofeedback, is more therapeutically demanding because the training parameters, i.e., primarily the electrode position and training frequency, are individually adapted to the patient's symptoms.
But no matter which type of neurofeedback professional users choose: at BEE Medic we have solutions for frequency band training, ILF, alpha-theta and synchrony neurofeedback as well as for tomographic neurofeedback or even with virtual reality, which are modular and no matter which type you want to start with, you can always expand your repertoire of treatment protocols.


V - Virtual Reality
Research shows that three-dimensional neurofeedback animation can lead to improved therapy outcomes and higher patient motivation.

Virtual reality (VR) usually refers to computer-generated environments. Through real-world movement users can navigate through the virtual world. The VR glasses enable users to enter the virtual world and interact with it. VR is often compared with video games, although the difference consists in the fact that users do not only control a character, but are the character. VR consequently offers possibilities to simulate experiences in protected spaces, including therapeutic uses.

We know that feedback animations in form of a video game lead to more effective outcomes than audio-visual content alone (Hafeez et al., 2019). Studies using virtual reality neurofeedback indicate greater learning success as well as better attention and impulsivity control than two-dimensional neurofeedback (Berger & Davelaar, 2018; Cho et al., 2004). And also relaxation can successfully be trained with VR neurofeedback (Gu & Frasson, 2017). VR neurofeedback can furthermore increase patients' motivation, interest, and also their sense of control during therapy.

The use of virtual reality in a therapeutic setting can therefore be helpful, especially for patients with anxiety disorders and phobias, but also for post-traumatic stress disorders, ADHD or chronic pain.

Cygnet® Virtual Reality combines state-of-the-art virtual reality technology with neurofeedback. The virtual worlds simulated in this feedback animation provides an unprecedented audio-visual neurofeedback experience to the patients.


W - Webinar
Our free webinars with experienced instructors are the ideal introduction to neurofeedback. 

Neurofeedback can be a therapy component in the treatment of numerous mental illnesses. But "healthy" people can also benefit from neurofeedback - this is referred to as peak or high-performance training. At our neurofeedback info days and webinars, you will get an overview of the current status, mechanisms of action and what characterizes modern neurofeedback methods and makes them so effective.

During the two-hour events, an experienced lecturer will give you a well-founded overview of the development of neurofeedback, the areas of application and what possibilities neurofeedback opens up today, thanks to modern signal processing. We will introduce you to the neurofeedback setting and there will be enough room for all your questions about neurofeedback. And all of that for free!


X - x23/x39
With our x23 / x39 QEEG device  the NeuroAmp is a up to 39 channel EEG amplifier for EEG and ERP based diagnostics. For research purposes, clinic and neurological practice.

If you are working with our Neurofeedback solutions you know that the NeuroAmp together with the Cygnet Neurofeedback software ist the core of our products. It enables effective and  powerful 2 channel Neurofeedback.

But did you know that the NeuroAmp can do even more than that? It is developed in such a way that it can be expanded modularly at any time e.g. with our x23 / x39 QEEG device. The NeuroAmp can then be also used as a 23/39 channel EEG amplifier. For neurodiagnostics, EEG / ERP Research or EEG biomarker development.

Y - Y neurofeedback?
 Y (Why) neurofeedback? There are many reasons for neurofeedback. We will show you a few very personal reasons

"If someone had told me a year ago that my son would grow up to be a bookworm, I would have shaken my head in disbelief."
- Mother of an autistic boy


"Neurofeedback brings ease to therapy."
- Gunnila Radu, Nordic Center of Neurofeedback


"The nice thing is that neurofeedback brings an ease to therapy and successes show up quickly. Sleep and mood improve and many patients report a sense of well-being after just a few sessions, feeling more confident and tidier in their minds."
- PD Dr. rer. nat. Meike Wiedemann


"Although I knew a lot about the process and effect of neurofeedback beforehand, I was totally surprised how quickly you notice an effect or a change. It only takes a few minutes and even minimal frequency differences have a completely different effect. And that's despite the fact that you don't have to actively do anything at first and basically just look at a screen."
- Participant of one of ouf online basic courses in 2021


Z - Zero
0,0001 Hz

In ILF neurofeedback we work with very low frequencies. ILF stands for Infra Low Frequency and especially neurofeedback with frequencies down to 0.0001 Hz is particularly effective. In the meanwhile German standard book "Praxisbuch Biofeedback und Neurofeedback" ILF Neurofeedback is also called "bridge between the original frequency band training (...) and the training of slow cortical potentials (SCP training)".
