'[[File:Neurofeedback gráfico.JPG|right|300 px|thumb|Sofware real time data of Neurofeedback trainning.]] '''Neurofeedback (NFB)''', also called '''neurotherapy''', '''neurobiofeedback''' or '''EEG biofeedback''' is a type of [[biofeedback]] that uses realtime displays of [[electroencephalography]] or [[fMRI|functional magnetic resonance imaging (fMRI)]] to illustrate brain activity, often with a goal of controlling [[central nervous system]] activity. Sensors are placed on the scalp to measure activity, with measurements displayed using [[video display]]s or sound. ==Definition== Neurofeedback is a type of [[biofeedback]] that uses [[electroencephalography]] or [[fMRI]] to provide a signal that can be used by a person to receive feedback about brain activity. Proponents claim that neurofeedback is an effective intervention for [[ADHD]] and [[epilepsy]], and research is being performed to investigate the effectiveness of the technique for treating [[autism]], headaches, insomnia,<ref>[http://www.ncbi.nlm.nih.gov/pubmed/19826944]</ref> anxiety, substance abuse, TBI.<ref>Thornton, K. & Carmody, D.

Barkley and Loo <ref>Barkley, R. A. & Loo, S. (2005). Clinical utility of EEG in attention deficit hyperactivity disorder. Applied Neuropsychology, 12(2), 64-76</ref> reviewed the available literature in 2005 on neurotherapy's effectiveness in treating ADHD and concluded that most early studies were uncontrolled [[case studies]], failed to use any control groups,did not use blinded methods to insure that parents, teachers, and clinicians were not aware of treatment assignments of the patients, and thus could have results largely if not entirely due to the [[placebo effect]]. Other studies used improper techniques for statistical analysis of their data and most failed to show if changes occurred in the EEG as a consequence of training which is critical if one is claiming that any resulting improvements in ADHD are due to the training itself. One also needs to show whether such changes in the EEG were statistically related to the improvements reported in ADHD symptoms. The authors concluded that evidence for the effectiveness of neurofeedback for ADHD was far from definitive and far more rigorous research was needed. Subsequent studies of this treatment for ADHD have now been published using larger samples, more appropriate control groups receiving alternative, attention placebo, or even sham neurofeedback control treatments as well as better assessment methods for ADHD symptoms. These more recent studies along with any early ones using appropriate scientific methods and published through 2010 were recently reviewed by Nicholas Lofthouse, Ph.D. and colleagues <ref>Lofthouse, N. et al. (2011). A review of neurofeedback treatment for pediatric ADHD. Journal of Attention Disorders, 1087054711427530, first published online November 16, 2011 as {{doi|10.1177/1087054711427530}}.</ref> and discussed in a separate paper <ref>Lofthouse, N. et al. (2011). Biofeedback and neurofeedback treatment for ADHD. Psychiatric Annals, 41(1), 42-47.</ref> that concluded that neurofeedback was probably efficacious but that the available evidence was hardly conclusive. Neither of these reviews included the results of his own rigorously conducted randomized trial of neurofeedback against sham feedback reported at a recent scientific meeting that found no benefits of biofeedback compared to the sham control condition. Of two studies published in 2010-2011 that both used attention placebo or sham control treatment groups, one found evidence of specific treatment effects only on inattention but not hyperactive or impulsive symptoms while the other smaller study found chiefly placebo effects.<ref>Bakhshayesh, N.

(2009). Efficacy of neurofeedback treatment in ADHD. Clinical EEG and Neuroscience, 40(3), 180-189.</ref> including many of the earlier poorly controlled studies that did not meet the methodological requirements for inclusion in the Lofthouse review. Further research on the benefits of neurofeedback for ADHD is clearly warranted given this history of mixed results, especially in the more recent and better conducted studies. As Lofthouse and colleagues admonished in their reviews, future research on this treatment needs to employ appropriate sham neurofeedback or other attention-placebo control groups, double-blinded procedures to insure that parents, teachers (and clinicians reporting on outcomes) are not aware of treatment group assignment, and measures of ADHD collected both in school and at home to better evaluate the efficacy of this treatment for ADHD.

During the years 1929-1938 he published 14 reports about his studies of EEGs, and much of our modern knowledge of the subject, especially in the middle frequencies, is due to his research.<ref name = "Kaiser">Kaiser, David A. "Basic Principles of Quantitative EEG." ''Journal of Adult Development'', Vol. 12, Nos. 2/3, August 2005</ref> Berger analyzed EEGs qualitatively, but in 1932&nbsp;G. Dietsch applied [[Fourier analysis]] to seven records of EEG and became the first researcher of what later is called QEEG (quantitative EEG).<ref name = "Kaiser" /> Later, Joe Kamiya popularized neurofeedback in the 1960s when an article<ref name="Kamiya1971">{{cite journal | author = Kamiya, J. | year = 1971 | title = Operant Control of the EEG Alpha Rhythm and Some of its Reported Effects on Consciousness | journal = Biofeedback and Self-Control: an Aldine Reader on the Regulation of Bodily Processes and Consciousness }}</ref> about the alpha brain wave experiments he had been conducting was published in ''Psychology Today'' in 1968. Kamiya’s experiment had two parts. In the first part, a subject was asked to keep his eyes closed and when a tone sounded to say whether he thought he was in [[alpha rhythm|alpha]]. He was then told whether he was correct or wrong. Initially the subject would get about fifty percent correct, but some subjects would eventually develop the ability to distinguish between states and be correct a highly significant percentage of the time. In the second part of the study, subjects were asked to go into alpha when a bell rang once and not go into the state when the bell rang twice. Once again some subjects were able to enter the state on command. Others, however, could not control it at all. Nevertheless, the results were significant and very attractive. Alpha states were connected with relaxation, and alpha training had the possibility to alleviate stress and stress-related conditions. Despite these highly dramatic claims, the universal correlation of high alpha density to a subjective experience of calm cannot be assumed. Alpha states do not seem to have the universal stress-alleviating power indicated by early observations.<ref name="Hardt1978">{{cite journal | author = Hardt, J.V. | coauthors = Kamiya, J. | year = 1978 | title = Anxiety change through electroencephalographic alpha feedback seen only in high anxiety subjects | journal = Science | volume = 201 | issue = 4350 | pages = 79–81 | doi = 10.1126/science.663641 | pmid = 663641 }}</ref> However, this is not cause to reject the concept of biofeedback entirely. Many other biofeedback treatments have emerged, since Kamiya’s alpha experiments. At one point, [[Martin Theodore Orne|Martin Orne]] and others challenged the claim that alpha biofeedback actually involved the training of an individual to voluntarily regulate brainwave activity.<ref name="Paskewitz1973">{{cite journal | author = Paskewitz, D.A. | coauthors = Orne, M.T. | year = 1973 | title = Visual Effects on Alpha Feedback Training | journal = Science | volume = 181 | issue = 4097 | pages = 360–363 | doi = 10.1126/science.181.4097.360 | pmid = 4719909 }}</ref> James Hardt and Joe Kamiya, then at [[University of California, San Francisco|UC San Francisco]]'s [[Langley Porter Psychiatric Institute|Langley Porter Neuropsychiatric Institute]] published a paper,<ref name="Hardt1976">{{cite journal | author = Hardt, J.V. | coauthors = Kamiya, J. | year = 1976 | title = Conflicting results in EEG alpha feedback studies | journal = Applied Psychophysiology and Biofeedback | volume = 1 | issue = 1 | pages = 63–75 | url = http://www.springerlink.com/index/Q6XU641775678664.pdf | accessdate = 2007-12-05 }}</ref> proving the efficacy of EEG biofeedback training, and that it was not just related to visuo/motor eyes open or closed factors. In the late sixties and early seventies, [[Barbara Brown (scientist)|Barbara Brown]], one of the most effective popularizers of Biofeedback, wrote several books on biofeedback, making the public much more aware of the technology. The books included ''New Mind New Body'', with a foreword from [[Hugh Downs]], and ''Stress and the Art of Biofeedback''. Brown took a creative approach to neurofeedback, linking brainwave self-regulation to a switching relay which turned on an electric train. The work of Barry Sterman, Joel F. Lubar and others has indicated a high efficacy for beta training, involving the role of sensorimotor rhythmic EEG activity.<ref name="Sterman1962">{{cite journal | author = Sterman, M.B. | coauthors = Clemente, C.D. | year = 1962 | title = Forebrain inhibitory mechanisms: cortical synchronization induced by basal forebrain stimulation | journal = Exp Neurol | volume = 6 | pages = 91–102 | doi = 10.1016/0014-4886(62)90080-8 | pmid = 13916975 | issue = 2 }}</ref> This training has been used in the treatment of epilepsy,<ref name="Sterman1972">{{cite journal | author = Sterman, M.B. | coauthors = Friar, L. | year = 1972 | title = Suppression of seizures in an epileptic following sensorimotor EEG feedback training | journal = Electroencephalogr Clin Neurophysiol | volume = 33 | issue = 1 | pages = 89–95 | doi = 10.1016/0013-4694(72)90028-4 | pmid = 4113278 }}</ref><ref name="Sterman2000">{{cite journal | author = Sterman, M.B. | year = 2000 | title = Basic concepts and clinical findings in the treatment of seizure disorders with EEG operant conditioning | journal = Clin Electroencephalogr | volume = 31 | issue = 1 | pages = 45–55 | pmid = 10638352 }}</ref> attention deficit disorder and hyperactive disorder,.<ref name="Lubar1995">{{cite journal | author = Lubar, J.F. | coauthors = Swartwood, M.O.; Swartwood, J.N.; O'Donnell, P.H. | year = 1995 | title = Evaluation of the effectiveness of EEG neurofeedback training for ADHD in a clinical setting as measured by changes in TOVA scores, behavioral ratings, and WISC-R performance | journal = Applied Psychophysiology and Biofeedback | volume = 20 | issue = 1 | pages = 83–99 | url = http://www.springerlink.com/index/L2213885102N16W6.pdf | accessdate = 2007-12-05 }}</ref> The sensorimotor rhythm (SMR) is rhythmic activity between 12 and 16 hertz that can be recorded from an area near the sensorimotor cortex. SMR is found in waking states and is very similar if not identical to the sleep spindles that are recorded in the second stage of sleep. For example Sterman has shown that both monkeys and cats who had undergone SMR training had elevated thresholds for the convulsant chemical monomethylhydrazine. These studies indicate that SMR is associated with an inhibitory process in the motor system and therefore increasing SMR through operant conditioning increases the ability to control seizures.<ref name=Sterman2000 /> Neuroimaging studies have correlated ADHD with abnormal functioning in the anterior cingulate cortex (ACC) during tasks involving selective attention. In 2006, Johanne Levesque et al. published results from their fMRI study showing normalization of ACC activation during a selective-attention task in ADHD subjects who had undergone neurofeedback training. Subjects in the study were randomly assigned to either the neurofeedback treatment group or a no-treatment control group, and subjects from the latter showed no difference in ACC activation compared to their baseline.<ref>Levesque, Johanne and Mario Beauregard.

For years, EEG biofeedback was treated as a minor part of the field of biofeedback, particularly by the primary biofeedback organization, [http://www.aapb.org AAPB]. In 1993, three different efforts, somewhat overlapping, dramatically increased the energy and influence of EEG biofeedback. In February 1993, Rob Kall, president of Futurehealth, organized the first annual [http://www.brainmeeting.com Winter Brain Meeting], in Key West Florida. The meeting brought together many of the leading figures in the field and it created a setting where the leaders could discuss and plan strategies for building greater influence and organization to move the field forward. In April 1993, Ken Tachiki, Jim Smith and Bob Grove organized a meeting of leaders in the field of Neurofeedback on Catalina Island, immediately before the 1993 AAPB meeting. Further planning took place at this meeting and the beginnings of SSNR occurred. SSNR= Society for the Study of Neuronal Regulation. Since then, SSNR has evolved to become ISNR International Society for Neuronal Regulation, and is now known as the International Society for Neurofeedback & Research [http://www.isnr.org ISNR]. Immediately after the Catalina meeting, at the 1993 AAPB meeting, a new EEG section was formed, after plenty of lively discussion. It quickly grew to become the biggest section of the organization. Things were never the same at AAPB. Neurofeedback had become a mainstream part of the field, though it took a few years to fully integrate into the annual meeting and journals. Within the last 5–10 years, neurofeedback has taken a new approach, in taking a second look at deep states. Alpha-theta training has been used in the treatment of alcoholism,<ref>http://www.neurofeedback-scotland.com/alpha-theta-brainwave.html</ref> other addictions as well as [[anxiety]].<ref>http://www.neurofeedback-scotland.com/anxiety-disorders.html</ref> This low frequency training differs greatly from the high frequency beta and SMR training that has been practiced for over thirty years and is reminiscent of the original alpha training of Elmer Green and Joe Kamiya. Beta and SMR training can be considered a more directly physiological approach, strengthening sensorimotor inhibition in the cortex and inhibiting alpha patterns, which slow metabolism. Alpha-theta training, however, derives from the psychotherapeutic model and involves accessing of painful or repressed memories through the alpha-theta state. The alpha-theta state is a term that comes from the representation on the EEG. The most recent development in the field is a conceptual approach called the Coordinated Allocation of Resource Model (CAR) of brain functioning which states that specific cognitive abilities are a function of specific electrophysiological variables which can overlap across different cognitive tasks.<ref>Thornton, K. & Carmody, D. Eyes-Closed and Activation QEEG Databases in Predicting Cognitive Effectiveness and the Inefficiency Hypothesis, Journal of Neurotherapy, 2009, (13) 1, 1-22</ref> The activation database guided EEG biofeedback approach initially involves evaluating the subject on a number of academically relevant cognitive tasks and compares the subject's values on the QEEG measures to a normative database, in particular on the variables that are related to success at that task. The approach has been able to improve auditory memory some 3 standard deviations (or 300%) in a group of 20 memory impaired learning disabled and attention deficit disorder children. The subject's memory was better than the control group following the treatment.<ref>Thornton, K. & Carmody, D. EEG Biofeedback for Reading Disabilities and Traumatic Brain Injuries.

The questionnaire specifies the complaints and also helps to indicate if the referral to a specialist might be called for. In some cases but not all a full EEG will be recorded. # If a full EEG is called for, the EEG recording is typically done on 19 - 21 sites on the scalp. It results in a brainmap ("quantitative EEG"). This is a series of maps (for each frequency one) where for each measured spot the average level of activity is shown. The brainmap is compared to a database to determine spots of over- and under activity compared to the average people of the patient's age and sex. There are several commercial providers of such databases. # The actual session itself involves placing sensors on the head. The feedback may involve, for example, a simple light or tone or game that will move and play when certain brain activity is detected by the system. For other brain activity the rewarding tone, or light or game is taken away. # A typical course of sessions takes 20 to 40 visits. At the beginning of each session the patient reports the course of his complaints and also mentions other mental effects. On the basis of this report the therapy may be adjusted. In some cases a patient is allowed to take a feedback machine home and have most - but not all - sessions there.
