“…From the very early studies conducted in late 70s by Bird, Newton, Sheer, and Ford (Bird et al, 1978ab, Ford et al, 1980 ) on EEG gamma frequency neurofeedback, 40 Hz activity was considered as a psychophysiological biomarker of attention in humans, and further research on association of the 40 Hz-centered gamma activity with attention, especially in neurodevelopmental disorders such as ASD definitely warrants further explorations, either as stand-alone treatment or as an adjunct arm in a combined treatment similar to one used in this study.…”

Autism spectrum disorder (ASD) is a pervasive developmental disorder characterized by deficits in social interaction, language, stereotyped behaviors, and restricted range of interests. In previous studies low frequency repetitive transcranial magnetic stimulation (rTMS) has been used, with positive behavioral and electrophysiological results, for the experimental treatment in ASD. In this study we combined prefrontal rTMS sessions with electroencephalographic (EEG) neurofeedback (NFB) to prolong and reinforce TMS-induced EEG changes. The pilot trial recruited 42 children with ASD (~14.5 yrs). Outcome measures included behavioral evaluations and reaction time test with event-related potential (ERP) recording. For the main goal of this exploratory study we used rTMS-neurofeedback combination (TMS-NFB, N=20) and waitlist (WTL, N=22) groups to examine effects of 18 sessions of integrated rTMS-NFB treatment or wait period) on behavioral responses, stimulus and response-locked ERPs, and other functional and clinical outcomes. The underlying hypothesis was that combined TMS-NFB will improve executive functions in autistic patients as compared to the waitlist group. Behavioral and ERP outcomes were collected in preand post-treatment tests in both groups. Results of the study supported our hypothesis by demonstration of positive effects of combined TMS-NFB neurotherapy in active treatment group as compared to control waitlist group, as the TMS-NFB group showed significant improvements in behavioral and functional outcomes as compared to the waitlist group.

“…A high-frequency EEG activity centered at 40-Hz (36-44 Hz) has been found to co-vary with focused arousal, a functional component of the multi-dimensional attentional process [109][110][111][112][113][114]. Focused arousal, its brain circuitry, and direct electrical measurement procedure, and its relationship with an EEG activity within a 36-44 Hz frequency band, centering at 40-Hz has been described by Sheer [115,116].…”

Hypnotizability is a dispositional trait reflecting the individual ability to modify perception, memory and behavior according to imaginative suggestions. It is measured by validated scales that classify the general population in high (highs), medium (mediums) and low (lows) hypnotizable persons, predicts the individual proneness to respond to suggestions, and is particularly popular in the field of the cognitive control of pain and anxiety. Different hypnotizability levels, however, have been associated with specific brain morpho-functional characteristics and with peculiarities in the cognitive, sensorimotor and cardiovascular domains also in the ordinary state of consciousness and in the absence of specific suggestions. The present scoping review was undertaken to summarize the asymmetries observed in the phenomenology and physiological correlates of hypnosis and hypnotizability as possible indices of related hemispheric prevalence. It presents the findings of 137 papers published between 1974 and 2019. In summary, in the ordinary state of consciousness, behavioral, neurophysiological and neuroimaging investigations have revealed hypnotizability related asymmetries mainly consisting of pre-eminent left hemisphere information processing/activation in highs, and no asymmetries or opposite directions of them in lows. The described asymmetries are discussed in relation to the current theories of hypnotizability and hypnosis.

“…Prior studies showed that the EEG gamma band (40 Hz) is enhanced in a whole range of cognitive processes, according to studies which used simple bandpass measurements. Application of the 40 Hz EEG band for neurofeedback has a long history, however, early studies were targeting only training of focused attention (Bird, Newton, Sheer, &Ford, 1978ab;Ford, Bird, Newton, & Sheer, 1980). These measurements probably confounded at least two different sources of the 35-45 Hz rhythms, one of which comes from the relay nuclei in the peripheral thalamus and may be similar to beta rhythms, reflecting arousal and attention.…”

Background: In addition to well-known cognitive impairments, there are disruptions in processing emotions in individuals with substance dependence and in those predisposed to drug abuse. Neurofeedback training-based intervention is one of the potentially efficacious nonpharmacological treatment options for substance use disorders. Several neurofeedback protocols which reported success in treating addictive behaviors have been employed. However, there are no studies on the use of neurofeedback in occasional drug users who have a drug use history have not yet developed substance use disorder or substance dependence. Method: We tested a protocol that may be useful to prevent drug abuse through self-regulation training aimed at enhancing EEG measures of positive emotional states. One of the aims of this pilot case series study was to determine the dynamics of self-reported perceived positive emotional state rating before, during and after twelve 25-minute long neurofeedback training course in two groups of subjects. One group of subjects (N=6) had a documented drug use history, most of them referred from the local metro operated mental health community center for adolescents; and the other group were drug-naïve subjects (N=5), recruited mostly from undergraduate students. Our hypothesis was that learning to increase the prefrontal 40 Hzcentered EEG band (a gamma frequency) power over 12 training sessions is possible and will be accompanied by increased ratings of positive affect. We trained subjects to increase a 40 Hz gamma measure (i.e., a "clarified 40 Hz-centered gamma" index termed "Neureka!") at a prefrontal site above FPz, in the middle of the forehead, referenced to the left ear. Results and Discussion: Neurofeedback training was accompanied by a highly significant linear increase of the "40 Hz gamma" measure and a less significant change in the relative power of the gamma activity in 35-45 Hz range. Individual reports of self-recorded happiness scores assessed during each neurofeedback session using the Continuous Response Digital Interface (CRDI) showed a linear increase both during and across training sessions. Both posttraining evaluations and 3.9 months follow-ups showed increased happiness ratings in both groups of subjects in this study. Neurofeedback training also resulted in better performance on the MicroCog and IVA+Plus neurocognitive tests. Conclusion: This proposed neurofeedback training method is promising for increasing both present happiness and future health. It needs further research and clinical trials to be validated as a method of positive emotion self-regulation in adolescents, particularly those predisposed towards drug abuse.
