This review traces the application of electroencephalographic (EEG) operant conditioning, or biofeedback, from animal research to its emergence as an alternative treatment for the major types of seizure disorder. Initial animal studies focusing on brain mechanisms that mediate learned behavioral inhibition revealed a uniquely correlated 12- to 15-H...

This review provides an updated overview of the neurophysiological rationale, basic and clinical research literature, and current methods of practice pertaining to clinical neurofeedback. It is based on documented findings, rational theory, and the research and clinical experience of the authors. While considering general issues of physiology, lear...

The treatment of epilepsy through operant conditioning of the sensorimotor rhythm electroencephalogram has a 35-year history. Neurophysiological studies have shown that this phasic oscillation reflects an inhibitory state of the sensorimotor system. Operant learning of sensory motor rhythm production results in an upregulation of excitation thresho...
Article
A new quantitative EEG metric is described here that examines the temporal correspondence of magnitude modulation between cortical recording sites. It is termed “comodulation,” and is applied as a cross-correlation analysis either within-subject or statistically between subject and a control database. Analysis can be performed for any selected freq...
Article
Two issues concerning sensorimotor EEG operant conditioning, or biofeedback, as a therapeutic modality for the treatment of seizure disorders are the focus of this review. The first relates to the question of whether relevant physiological changes are associated with this procedure. This question is addressed through review of an extensive neurophy...

The AAN/ACNS report is misleadingly negative regarding the current status of quantitative EEG and tends to discourage its development and use with other related clinical problems. There have been many excellent studies showing that QEEG can be useful for the evaluation and understanding of mild traumatic brain injury, learning disabilities, attenti...
Article
Averaged event-related EEG frequency response profiles were generated from normalized spectral analysis data obtained in 2 studies of short-term memory. A continuous performance task was used requiring a keyboard response to targeted letter sequences presented on a video screen at 2 sec. intervals. Seven 2 Hz frequency bands between 5–15 Hz were ev...
Article
In a previous study of simulated vehicle performance we found that stationary visual attention and body movements alone produced selective effects on topographic EEG frequency patterns. In the present study we focus on an expanded set of these task components. EEG, EOG and ECG data were recorded from 21 subjects during instructed driving movements...
Article
Recent neurophysiological findings in relation to thalamocortical mechanisms for sensory processing, together with established anatomical and expanding functional evidence, have provided a rational theoretical framework for the interpretation of normal and abnormal EEG rhythmic activities. This perspective is integrated here with earlier animal stu...

... In this work, the following spectral measures were calculated to assess the spectral couplings between different oscillatory activities from LFP recordings: www.nature.com/scientificreports/ where ρ i,j is the cross-frequency comodulation 69,70 (i.e., the Pearson product moment correlation of spectral magnitudes) between the spectral power SP(f) at a frequency f i and at another frequency f j within the same LFP spectrum. The term SP �t κ (f i ) is the spectral power at frequency f i in time-window �t κ and the term SP(f i ) is the average spectral power magnitude at frequency f i over all time-windows ranging in k. ...
... The remaining EEG epochs maintained greater than 95% split-half and greater than 90% test-retest reliability coefficients as computed by NeuroGuide with at least 1.5 total minutes of artifact-free data remaining for analysis. Each participant record was then filtered offline between 1 and 30 Hz and exported into separate text files containing 2-s segments using a 75% overlapping taper window (Kaiser & Sterman, 2000). ...
... The literature on interpretating changes in spectral power during appropriateness evaluations is scarce. In general, alpha band desynchronization has been related to memory retrieval operations while processing language (e.g., Klimesch et al., 1997;Sterman et al., 1996), whereas alpha synchronization seems to reflect the neutralization of task-irrelevant regions (Jensen & Mazaheri, 2010). More specifically, several studies report alpharelated desynchronization when participants process nonliteral language such as irony (Akimoto & Miyazawa, 2017;Regel et al., 2014;Spotorno et al., 2013). ...
... In healthy people, NFb is believed to enhance cognitive functions and attention processes and helps improve behavior and well-being. A number of brain waves have been targeted during NFb, among which sensory-motor rhythms (SMR) (12)(13)(14)(15) [1][2][3][4] have been associated with improved attentional processes [5][6][7], even in healthy subjects [8,9] who did not suffer from any brain disease. A drawback with such interventions is that people have been submitted to several sessions of SMR-NFb [8][9][10], which poses the question of acceptability. ...
... Ritmo sensoriomotor (12-15 Hz) es característico de la corteza motora y sensorial. Esta asociada a la motricidad y en cierta medida con la asistencia a la atención sostenida o a la memoria verbal de trabajo (Gruzelier y col., 2010) y su entrenamiento se ha visto vinculado a la mejora de pacientes epilépticos (Sterman, 2010;Sterman y Egner;2006). ...
... During the experiment, the participants sat in a room with a controlled environment. The EEG signals were recorded according to the international 10-20 system (Fp1, Fp2, F3, F4, F7, F8, C3, C4, T3, T4, P3, P4, T5, T6, O1, O2, Fz, Cz, and Pz), with a sampling frequency of 256 Hz, feedback was from Cz channel (it was chosen since it is at the primary motor cortex and has been associated with sensory information processing over the sensorimotor area and provide a measurement of the activity in both hemispheres and in the frontal lobe) [17,18], the ground was located at forehead and the reference was the average of left and right mastoids. The signals were amplified by a 24-channel system (Vertex 823 from Meditron Electomedicina Ltd.a, São Paulo, Brazil) and were recorded by Somnium software platform (Cognitron, São Paulo, Brazil) and NF module by Laseeb-ISR. ...
... Diagnosis can also benefit from the complementary information exhibited by SPECT images displayed in a variety of formats including slices, surfaces and volumes. The optimal approach to accomplish accurate and efficient interpretation of brain imaging modalities is debated by researchers and clinicians in the literature (2)(3)(4)(5)(6)(7), with discussions primarily centered on either conventional visual analysis by an experienced investigator and/or quantification techniques including voxel-wise analysis or region of interest (ROI) approaches (8)(9)(10)(11)(12). SPECT image quantification within clinical research typically identifies statistically significant differences based on mean group values, which do not always equate to individual differences, which is typically the focus in clinical practice (8). ...
... Its tolerance toward false alarms leading to unnecessary interventions would depend on the magnitude of side effects. The principal feasibility of different seizure-intervention strategies such as local application of short-acting drugs (Stein et al., 2000), electrical stimulation techniques (Berényi et al., 2012), local cooling (Hill et al., 2000), or biofeedback operant conditioning (Sterman, 2000) has been described in the literature. Presently, much research is directed toward designing a closed-loop intervention system using deep brain or transcranial stimulation (Morrell, 2006;Kozák and Berényi, 2017;Takeuchi et al., 2021). ...
... Egner and Gruzelier (2001) showed that uptraining sensory-motor rhythm (SMR; in the range of 12-15 Hz) was linked to decreased errors on the Continuous Performance Test (CPT), increased attention and might address problems of inhibitory control (Egner and Gruzelier 2001). The enhancement of SMR activity has been proposed to be influential for reduction of impulsiveness/ hyperactivity (Lubar and Shouse 1976) and enhancing attention more generally (Egner and Sterman 2006;Sterman et al. 1970;Tsatali et al. 2019). It is also suggested that the effects of SMR training on attention performance might support the idea that training results in decreased motor interference in attentive cognitive processing (Marlats et al. 2020;Sterman 1996). ...
