Learned self-regulation of EEG frequency components affects attention and event-related brain potentials in humans

  author={Tobias Egner and John H. Gruzelier},
Learned enhancement of EEG frequency components in the lower beta range by means of biofeedback has been reported to alleviate attention deficit hyperactivity disorder (ADHD) symptoms. In order to elucidate frequency-specific behavioural effects and neurophysiological mediators, this study applied neurofeedback protocols to healthy volunteers, and assessed impact on behavioural and electrocortical attention measures. Operant enhancement of a 12–15 Hz component was associated with reduction in… 

Neurofeedback of Theta and Beta Frequencies: Effects on Selective Attention and Response Inhibition

The present research was not conclusive regarding the NF conditions that might have contributed to improvements in target processing efficiency and cancellation of a previously prepared response in previous studies.

Ecological validity of neurofeedback: modulation of slow wave EEG enhances musical performance

Improvements in musical performance in a student group that received training on attention and relaxation related neurofeedback protocols were documented, and improvements were highly correlated with learning to progressively raise theta over alpha band amplitudes.

Electrostimulation contingencies and attention, electrocortical activity and neurofeedback

This thesis has supplied novel evidence for significant cognitive and electrocortical effects of neurofeedback training and transcutaneous electro-acustimulation in healthy humans.

Effects of SMR and Theta/Beta Neurofeedback on Reaction Times, Spatial Abilities, and Creativity

This work investigated whether healthy individuals are able to learn, within 30 NFT sessions, how to modulate either the SMR or the TBR, and whether such modulation can lead to an enh...

Slow cortical potential and theta/beta neurofeedback training in adults: effects on attentional processes and motor system excitability

Overall, the results are limited by the non-sufficiently acquired self-regulation skills, but some specific effects between good and poor learners could be described.

Self-regulation of frontal-midline theta facilitates memory updating and mental set shifting

Frontal-midline (fm) theta oscillations as measured via the electroencephalogram (EEG) have been suggested as neural “working language” of executive functioning. Their power has been shown to

ERPs correlates of EEG relative beta training in ADHD children.




Operant conditioning of EEG rhythms and ritalin in the treatment of hyperkinesis

Although the procedure clearly reduced hyperkinetic behavior, a salient, specific therapeutic factor could not be identified due to the dual EEG contingency imposed combined with associated changes in EMG, which suggested the prognostic and diagnostic value of the SMR in the disorder when overactivity rather than distractibility is the predominant behavioral deficit.

A first attempt to explore the SMR biofeedback technique's applicability to the problem of hyperkinesis independent of the epilepsy issue and the subject population has recently been increased to establish the validity and generality of the findings.

Evaluation of the effectiveness of EEG neurofeedback training for ADHD in a clinical setting as measured by changes in T.O.V.A. scores, behavioral ratings, and WISC-R performance

The findings corroborate and extend previous research, indicating that neurofeedback training can be an appropriate and efficacious treatment for children with ADHD.

Physiological origins and functional correlates of EEG rhythmic activities: Implications for self-regulation

Basic evidence concerning the origins, frequency modulation, and functional significance of normal EEG rhythmic activities is reviewed here in an effort to provide guiding principles for the interpretation of clinical abnormalities and their remediation with EEG feedback training.

A Comparison of EEG Biofeedback and Psychostimulants in Treating Attention Deficit/Hyperactivity Disorders

There is not enough evidence from well controlled scientific studies at this time to support the effectiveness of EEG biofeedback for AD/HD children, concluded Barkley (1992), who criticized studies that used small numbers of subjects, lacked appropriate control groups, confounded treatment effects by using multiple interventions, and employed outcome measures susceptible to practice and/or placebo effects.

Thalamocortical dysrhythmia: A neurological and neuropsychiatric syndrome characterized by magnetoencephalography.

Spontaneous magnetoencephalographic activity was recorded in awake, healthy human controls and in patients suffering from neurogenic pain, tinnitus, Parkinson's disease, or depression, indicating the presence of a thalamocortical dysrhythmia which is responsible for all the above mentioned conditions.
