not is a specialist magazine aimed at patients with traumatic brain injuries, stroke, and other acquired brain injuries - while simultaneously offering insights for healthcare professionals, relatives, and interested parties. The magazine provides well-founded articles, practical tips, and current developments in the field of neurorehabilitation.

In March, the magazine published an article on the topic of ILF Neurofeedback in collaboration with BEE Medic:

Making changes in the brain visible
In neurological rehabilitation, neurofeedback is increasingly being used. This refers to methods in which the electrical activity of the brain is measured via electrodes on the surface of the scalp and analyzed using an electroencephalogram (EEG). The information obtained is translated into real-time feedback, for example through visual and auditory changes in a film or animation. In this way, the brain continuously receives information about its own activity. This feedback can enable changes in the organization and regulation of neuronal activity.

Symptom-based application
One possible approach is Infra-Low-Frequency Neurofeedback (ILF neurofeedback). Extremely slow changes in brain activity are included in the feedback, which are associated with higher-level processes of self-regulation and stabilization. ILF neurofeedback does not rely on conscious tasks but works predominantly on an unconscious level. In practice, it is applied based on symptoms. The starting point is specific complaints, understood as an expression of limited regulatory capacity. ILF neurofeedback is not used in isolation but combined with classical frequency band information. Only this combination constitutes the complete ILF neurofeedback protocol.

Imaging methods
In this context, imaging methods provide an additional perspective. Functional magnetic resonance imaging (fMRI) plays a central role here. It allows indirect measurement of changes in brain activity by assessing blood flow and oxygen supply in the brain. This makes it possible to map functional brain networks.
Against this background, a key question arises:
Can changes in the brain after neurofeedback be objectively demonstrated not only through symptom progression but also using imaging methods?

Extensive body of research
Numerous clinical studies already exist on the effectiveness of neurofeedback-based methods, including ILF neurofeedback. What has largely been missing so far, however, are imaging data showing whether and how different components of an established ILF neurofeedback protocol are reflected in the brain. A study published in December 2025 in the journal NeuroImage addresses exactly this question. The aim of the investigation was not to evaluate treatment outcomes but to examine whether objective changes in the brain can be detected after a single neurofeedback session and whether these depend on which signal components are used.
A total of 135 healthy adults participated in the study. The focus was therefore on fundamental neurophysiological effects rather than clinical treatment outcomes. Participants were divided into groups and received different forms of neurofeedback, using either individual signal components or their combination. Functional MRI was used before and after the session to assess changes in brain connectivity.

Results
The results show a clear pattern. Stable and statistically robust changes in functional connectivity were observed exclusively after application of the full ILF neurofeedback protocol, meaning the combination of classical frequency band information and infra-low-frequency signals. When the signal components were applied separately, no comparable stable changes could be detected.

Conclusion
Although the present study does not make statements about clinical effectiveness, its significance for understanding neurofeedback is considerable. Using imaging data, it shows that ILF neurofeedback is associated with stabilization and increased connectivity of functional brain networks.
The study does not add further effectiveness data to existing clinical studies but instead provides an imaging-based perspective on the underlying neurophysiological processes. For patients, this can serve as an important point of orientation. Neurofeedback can thus be understood not only through subjective experience but also through objectively measurable changes in the brain under clearly defined experimental conditions.

The Neuro-Bio-Practice was founded in November 2025 in the Rhein-Lahn District by Marcin Grabowski. His clear vision: to combine traditional occupational therapy expertise with modern neurotechnological methods. The focus is on therapy that is individually tailored to clients’ needs and oriented toward their real-life situations.

The practice treats a wide range of neurological, psychological, and psychosomatic conditions. These include, among others, attention and regulation issues such as ADHD, stress-related complaints, anxiety disorders, depressive symptoms, as well as chronic pain or sleep problems. People experiencing exhaustion or cognitive impairments—such as those related to Long COVID—will also find suitable therapeutic options here.
 

From Interest to Specialization

Marcin Grabowski’s journey into neurofeedback began early in his professional career. He received a formative impetus during his work in forensic medicine, where he first came into close contact with the subject. “The possibility of directly addressing the brain’s functioning fascinated me from the very beginning,” he recalls.

Since then, he has continuously pursued further training and deepened his knowledge of various neurofeedback methods. As early as 2018, he completed his training in ILF Neurofeedback according to Othmer. In the years that followed, he gained diverse practical experience, including working with individuals on the autism spectrum and those with post-traumatic stress disorder. 

Today, Marcin Grabowski combines various neurofeedback approaches with biofeedback, pursuing a client-centered and systemic therapeutic approach.
 

Focus on Modern Therapeutic Approaches

A particular focus of the Neuro-Bio-Practice is on the use of neurofeedback and biofeedback. Both methods are specifically employed to support therapeutic processes and make changes immediately tangible for clients.

Both ILF neurofeedback according to Othmer and classic frequency band training methods such as alpha-theta or synchrony protocols are employed. “Working with neurofeedback makes it possible to directly address the brain’s regulatory processes. Many clients are surprised at how immediately the first changes become noticeable, without any active effort on their part,” Marcin Grabowski describes his experience.

In addition, biofeedback is used to visualize physical processes such as breathing, muscle tension, or stress responses. This fosters a better understanding of one’s own body, opening up new possibilities for specifically influencing well-being.
 

Individualized Therapy for Different Life Stages

Daily practice is characterized by a wide variety of clients. From adolescents to adults to older adults, neurofeedback is used across different life stages. The method can also be used even when communication is limited, as it works directly on brain activity.

Many report initial changes in their daily lives as early as after the first few sessions. Statements like “I didn’t think it would be noticeable so quickly” or “I don’t have to actively do anything for this?” reflect these experiences well.
As therapy progresses, concrete improvements often emerge: improved concentration, greater inner calm, a more stable mood, or a changed approach to stress. These advances are continuously monitored and incorporated into further treatment planning.
 

Experiences that motivate

Particularly impressive is the feedback from clients who have already tried many therapeutic approaches and initially approach neurofeedback with skepticism. Often, after just a few sessions, they report greater clarity, inner stability, or improved resilience in daily life.

For example, a client with significant concentration and fatigue issues described how everyday tasks have become easier again and how he feels more mentally organized. Such developments strengthen trust in the therapeutic process and foster motivation for continued collaboration.
 

Proven Collaboration with BEE Medic

Marcin Grabowski has been working with BEE Medic systems since 2019. He particularly values the reliability of the devices as well as the practical training programs. “For me, it was important from the very beginning to integrate neurofeedback well into the practice, both technically and spatially. The systems have proven to be stable and reliable, which plays a major role in everyday therapeutic practice,” reports Marcin Grabowski.

Modern approaches such as virtual reality are also increasingly finding their place in therapy. They make it possible to actively involve patients and bring content to life in new ways. This is complemented by biofeedback sensors that make physical processes visible, thereby facilitating access to one’s own experience.thetic.
