HEG Neurofeedback info channel

Here you will find basic information about HEG neurofeedback. This is a procedure for self-regulation. Unlike conventional EEG neurofeedback, which requires a high degree of self-discipline and especially "sitting still" from the trainee, HEG is extremely easy to use, does not require any pre- and post-processing and is easy for the trainee to understand in its feedback effect.

The Potential of Functional Near-Infrared Spectroscopy-Based Neurofeedback—A Systematic Review and Recommendations for Best Practice
The Potential of Functional Near-Infrared Spectroscopy-Based Neurofeedback—A Systematic Review and Recommendations for Best Practice

Background: The effects of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI)-neurofeedback on brain activation and behaviors have been studied extensively in the past. More recently, researchers have begun to investigate the effects of functional near-infrared spectroscopy-based neurofeedback (fNIRS-neurofeedback). FNIRS is a functional neuroimaging technique based on brain hemodynamics, which is easy to use, portable, inexpensive, and has reduced sensitivity to movement artifacts.

Method: We provide the first systematic review and database of fNIRS-neurofeedback studies, synthesizing findings from 22 peer-reviewed studies (including a total of N = 441 participants; 337 healthy, 104 patients). We (1) give a comprehensive overview of how fNIRS-neurofeedback training protocols were implemented, (2) review the online signal-processing methods used, (3) evaluate the quality of studies using pre-set methodological and reporting quality criteria and also present statistical sensitivity/power analyses, (4) investigate the effectiveness of fNIRS-neurofeedback in modulating brain activation, and (5) review its effectiveness in changing behavior in healthy and pathological populations.

Results and discussion: (1–2) Published studies are heterogeneous (e.g., neurofeedback targets, investigated populations, applied training protocols, and methods). (3) Large randomized controlled trials are still lacking. In view of the novelty of the field, the quality of the published studies is moderate. We identified room for improvement in reporting important information and statistical power to detect realistic effects. (4) Several studies show that people can regulate hemodynamic signals from cortical brain regions with fNIRS-neurofeedback and (5) these studies indicate the feasibility of modulating motor control and prefrontal brain functioning in healthy participants and ameliorating symptoms in clinical populations (stroke, ADHD, autism, and social anxiety). However, valid conclusions about specificity or potential clinical utility are premature.

Conclusion: Due to the advantages of practicability and relatively low cost, fNIRS-neurofeedback might provide a suitable and powerful alternative to EEG and fMRI neurofeedback and has great potential for clinical translation of neurofeedback. Together with more rigorous research and reporting practices, further methodological improvements may lead to a more solid understanding of fNIRS-neurofeedback. Future research will benefit from exploiting the advantages of fNIRS, which offers unique opportunities for neurofeedback research.

Praxisnaher Zugang zu neuartigem Neurofeedback-Training

Neurofeedback gewinnt als Behandlungsform fortgesetzt an Bedeutung.
Das Spektrum an Behandlungs- und Anwendungsbereichen für Neurofeedback
nimmt ebenfalls stetig zu. Eine der größten Herausforderungen im
Einsatz von Neurofeedback ist die Behandlung von Kindern und Jugendlichen
(insbesondere mit ADS/ADHS), da EEG-basiertes Neurofeedback
leicht durch Artefakte beeinträchtigt werden kann. Ferner ist in diesen Fällen
bei einer typischen Behandlungsfrequenz von einmal wöchentlich eine
etwa ein Jahr währende Behandlung erforderlich, um ADS/ADHS wirksam
zu verbessern.
Diese Veröffentlichung beschreibt einen alternativen Weg der Neurofeedbackbehandlung.
Sie beruht auf dem Konzept nIR-basierten HEG-Neurofeedbacks
nach Toomin et. al. Die primäre Zielgruppe hier besteht aus
Kindern mit ADS/ADHS, Lese-Rechtschreibschwäche oder verwandten
Lernstörungen. Die Autoren untersuchen die Möglichkeiten und Effektivität
eines kompakt ausgestalteten täglichen Trainings über ein bis zwei
Intensivtrainings wochen. Das erklärte Ziel ist es, Kindern und Jugendlichen
mit Konzentrationsschwächen und mangelnder Ausdauer zu einem
Training zu verhelfen, das für sie gut durchführbar und erfolgreich ist, und
zwar in überzeugender und schneller Art und Weise.
