An Investigation into Discomfort and Fatigue Related to the Wearing of an EEG Neurofeedback Headset
Self-regulating brain activity using electroencephalography (EEG) neurofeedback has the potential to improve cognitive functions, rehabilitate motor control and reduce chronic fatigue. Nonetheless, user experience and factors which may interfere with the beneficial effects of neurofeedback are still under researched. This preliminary study aimed to investigate whether wearing an EEG neurofeedback recommended headset for 1 hour induced significant physical discomfort and fatigue. Data were obtained from a standard visual analogue scale questionnaire and a newly developed EEG headset discomfort (EEGhd) questionnaire. 21 participants (12 in the experimental (headset) and 9 in the control (electrodes only) group) watched a nature documentary video while their brain signals were recorded. They completed the set of questionnaires before and after the video, while wearing the EEG headset (or electrodes). A two-sample t-test revealed that the experimental group experienced significantly hig...

A wireless, dry, inexpensive and easy to use EEG home training device, adapted from the NeuroSky MindWave headset, will be presented, along with proof of concept data, Beta testing reactions and preliminary efficacy findings. Attention will be given to the development of the device and its use of four power-training protocols developed from the available NeuroSky bandwidth platform. Training and control screens will be illustrated. Finally, the benefits and limitations of the device will be discussed, with focus on its ease of use vs. the temporal, bandwidth and site restrictions of the training device.
What is Neurofeedback: An Update
Journal of Neurotherapy, 2011
Written to educate both professionals and the general public, this article provides an update and overview of the field of neurofeedback (EEG biofeedback). The process of assessment and neurofeedback training is explained. Then, areas in which neurofeedback is being used as a treatment are identified and a survey of research findings is presented. Potential risks, side effects, and adverse reactions are cited and guidelines provided for selecting a legitimately qualified practitioner.
A Wireless EEG System for Neurofeedback Training
Applied Sciences
This paper presents a mobile, easy-to-maintain wireless electroencephalograph (EEG) system designed for work with children in a school environment. This EEG data acquisition platform is a small-sized, battery-powered system with a high sampling rate that is scalable to different channel numbers. The system was validated in a study of live z-score neurofeedback training for quantitative EEG (zNF-qEEG) for typical-reading children and those with developmental dyslexia (DD). This system reads and controls real-time neurofeedback (zNF) signals, synchronizing visual stimuli (low spatial frequency (LSF) illusions) with the alpha/theta (z-α/θ) score neural oscillations. The NF sessions were applied during discrimination of LSF illusions with different contrasts. Visual feedback was provided with color cues to remodulate neural activity in children with DD and their cognitive abilities. The combined zNF-qEEG and training with different visual magnocellular and parvocellular tasks (VTs) comp...
The effects of electrode placement upon EEG biofeedback training: the monopolar-bipolar controversy
International Journal of Psychosomatics, 1989
Roles of tradition, convenience, and noise or artifact rejection are discussed with regard to the referential versus bipolar electrode placement controversy in electroencephalography (EEG). Particular emphasis is placed on the relevance to neurofeedback. The crucial interactions between the differential amplifier, brain waves, and referential/bipolar placements are discussed. Through logical analysis and empirical observation, it is demonstrated how the very nature of the EEG differential amplifier must destroy those elements of brain activity which are common (synchronous) to the recording electrodes. Controlled experiments further illustrate the critical importance of electrode placements. Various methods, including preferred electrode placements, are presented to help resolve recording problems that frequently arise. It is concluded that there are serious implications for researchers, EEG clinicians, neurofeedback providers, and their clients in preferring one type of electrode placement technique over another. EEG recording information is affected by this choice.
Review of the therapeutic neurofeedback method using electroencephalography: EEG Neurofeedback
Review of the therapeutic neurofeedback method using electroencephalography: EEG Neurofeedback, 2019
Electroencephalographic neurofeedback (EEG-NFB) represents a broadly used method that involves a real-time EEG signal measurement, immediate data processing with the extraction of the parameter(s) of interest, and feedback to the individual in a real-time. Using such a feedback loop, the individual may gain better control over the neurophysiological parameters, by inducing changes in brain functioning and, consequently, behavior. It is used as a complementary treatment for a variety of neuropsychological disorders and improvement of cognitive capabilities, creativity or relaxation in healthy subjects. In this review, various types of EEG-NFB training are described, including training of slow cortical potentials (SCPs) and frequency and coherence training, with their main results and potential limitations. Furthermore, some general concerns about EEG-NFB methodology are presented, which still need to be addressed by the NFB community. Due to the heterogeneity of research designs in EEG-NFB protocols, clear conclusions on the effectiveness of this method are difficult to draw. Despite that, there seems to be a well-defined path for the EEG-NFB research in the future, opening up possibilities for improvement.
