Multiple studies have stated that autonomous sensory meridian response (ASMR) induces relaxation. ASMR is defined as a static tingling-like sensation across the scalp and back of the head, experienced by some people in response to specific audio and visual triggers like tapping, whispering, and slow hand movements. This study explores the relaxation states and the stress states on which ASMR videos have the highest impact. Data from 60 college students with a mean age of 22 years and a standard deviation of 1.12 were collected for this study, among which 30 were assigned to an experimental group and 30 were assigned to a control group single blindly. The relaxation states and stress states were measured using Smith Relaxation Scale Inventory (SRSI) for the pretest and Smith Relaxation Posttest Inventory (SRPI) for the posttest. The experimental group watched an ASMR video, and the control group watched a neutral video between the pretest and posttest. SPSS version 16 was used for data analysis. The result suggested a significant increase in sleepiness after watching the ASMR video (significant difference).

Addictive disorders are characterized by cognitive, behavioral, and neurological impairments caused by dysregulations of brain structure that can extend well beyond early withdrawal in the months and years of recovery. The present study aimed to examine the efficacy of neurofeedback rehabilitation on anxiety in methamphetamine abusers. The sample consisted of 14 male methamphetamine drug addicts who were randomly assigned to an experimental group (n = 7) and a control group (n = 7). Participants were assessed for Axis I disorders (SCID) and the Beck Anxiety Inventory (BAI). Mixed repeated ANOVA, independent t-tests, and chi-square were used for data analysis. The experimental group received 18 sessions of neurofeedback rehabilitation and standard psychological interventions treatment as usual, while the control group received only standard interventions. Results showed that neurofeedback significantly reduced anxiety in methamphetamine abusers at posttreatment and during a one-month follow-up. Along with other psychological interventions, neurofeedback rehabilitation is recommended for methamphetamine abusers.

Introduction. The present study aimed to evaluate the effectiveness of neurofeedback (NFB) for the treatment of acquired cognitive impairment after brain tumor surgery. Methods. The patient was a 49-year-old bilingual African woman who underwent surgical craniotomy after a tuberculum sellae meningioma was diagnosed. Cognitive deficits were evident following post-surgical recovery, and therefore intensive NFB training consisting of 15 sessions was carried out over a period of three weeks. Full neuropsychological testing and quantitative EEG analysis were performed before and after the training for outcome measurements. Results. The treatment resulted in improved attention and executive functions; specifically sustained, focused, and divided attentional abilities; cognitive flexibility, access to the lexical vocabulary, and a better processing speed. Analysis of the qEEG revealed an increased alpha peak frequency value and reduced delta/alpha ratio in frontal areas. The EEG examination revealed interhemispheric asymmetry after treatment. Conclusion. These findings suggest that a delta/alpha decrease might account for some clinical effects on cognitive abilities seen in a brain tumor resection survivor, reducing cognitive symptoms that can have a significant impact on daily life functions. Future studies on larger patients’ samples should clarify the feasibility of NFB protocols for patients with brain tumors. have associated with positive cognitive outcomes (e.g., control and shifting, attention, executive functions, abstract reasoning, nonverbal intelligence).

Hypertension is among the leading causes of mortality and an important contributor toward disability-adjusted life years worldwide. Several factors contribute toward individuals’ risk to develop hypertension. Stress is considered an important pathogenic component affecting blood pressure regulation. However, systematic reviews examining the effect of psychosocial stressors and anxiety on hypertension produced spurious results. The observed heterogeneity in the operationalization of stress and subsequent reactivity hindered the characterization of the evidence for the association between exposure, physiological reactivity, and risk for hypertension. This is of paramount importance as physiological reactivity constitutes a biological interface mechanism through which stressors affect blood pressure regulation. The neural substrates of vagally mediated heart rate variability (VM-HRV) indicate that it is able to assimilate such an interfacing mechanism. Large-scale epidemiological studies provided substantial evidence linking decreases in VM-HRV with the development and progression of hypertension, indicating that individuals’ reactivity to stressors, as measured via VM-HRV, increases individuals’ risk for the development and progression of hypertension. As such, VM-HRV can reinforce current screening initiatives and support treatment-related prognosis. Self-regulation techniques, like heart rate variability biofeedback (HRVB), and neuromodulation techniques, like cranial electrotherapy stimulation (CES), are able to enhance VM-HRV and the associated parasympathetic modulation of cardiovascular outcomes, and thus address autonomic imbalances associated with hypertension.

Neurofeedback has gained great interest as a noninvasive treatment for various disorders. However, there is still a lack in literature regarding the effects of infra-slow fluctuation (ISF) neurofeedback training. ISF neurofeedback training is aimed at the lowest brainwave oscillations and attempts to balance dysregulated brainwave activity by inducing shifts in the parasympathetic and sympathetic response. The aim of this study was to determine whether ISF neurofeedback training has a significant effect in participants with insomnia by using quantitative electroencephalography (qEEG), Central Nervous System Vital Signs (CNS VS), and by measuring the changes of physiological vitals. The intervention consisted of 10 sessions for 40 participants separated equally into two groups. Significant results were achieved with improved core temperature ( p = .002), finger temperature ( p < .001), lower heart rate ( p = .002), systolic ( p = .003) and diastolic blood pressure ( p = .001). The qEEG components significantly improved within standard ranges. An improved neurocognitive state was achieved in terms of CNS VS, with a decrease in depression ( p = .003), anxiety ( p < .001), and stress ( p < .001). This study demonstrated that ISF neurofeedback training should be considered as a viable alternative that can be used concurrently with other insomnia treatment

The combination of modern machine learning and traditional statistical methods allows the construction of individual regression models for predicting the blood oxygenation level dependent (BOLD) signal of a selected region-of-interest within the brain using EEG signal. Among the many different models for motor cortex, we chose the EEG Fingerprint one-electrode approach, based on rigid regression model with Stockwell EEG signal transformation, used before only for the amygdala. In this study we demonstrate the way of finding suitable model parameters for the cases of BOLD signal reconstruction for five individuals: three of them were healthy, and two were after a hemorrhagic stroke with varying degrees of damage according to Medical Research Council (MRC) Weakness Scale. The principal possibility of BOLD restoring using regressor model was demonstrated for all the cases considered above. The results of direct and indirect comparisons of BOLD signal reconstruction at the motor region for healthy participants and for patients who suffered from a stroke are presented.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating disease of the central nervous system known to be associated with multiple behavioral symptoms (fatigue, low stamina, dizziness, etc.) combined with autonomic nervous system (ANS) dysfunction, thus implicating the central autonomic network (CAN). Postexertional malaise (PEM) is a core feature of ME/CFS, characterized by a pathological reduction in stamina in response to performing minor physical or mental tasks, often lasting at least 24 hours. Exact low-resolution electromagnetic tomography (eLORETA) allows noninvasive investigation of cortical regions of interest that may contribute to better understanding of the role of the brain disturbances in behavioral manifestations of PEM. This pilot study therefore aimed to use eLORETA to characterize changes in current density in cortical structures related to the CAN following submaximal isometric handgrip exercise in seven patients with ME/CFS and six neurotypical healthy controls (HCs). Resting EEG was recorded at pre- and posthandgrip, and 24 hours later. Findings showed that significant differences occurred immediately posttest, which were most pronounced after 24 hours, particularly in the low alpha (8–10 Hz) and low beta (13–18 Hz) frequency subbands. Together, the present findings offer support for EEG source localization techniques to investigate PEM. If confirmed, this study could provide a useful instrument for aiding functional diagnosis and evaluation of treatment outcomes.

This meta-analytical study examined the effect of neurofeedback (NF) on decreasing depression. The main finding of the meta-analysis was that NF resulted in a large ( g = −0.91) decrease in depression. This finding can be explained through the various roles of brainwave oscillations in terms of both the formation and persistence of depression and the development of oscillatory patterns less compatible with depressive states. One plausible mechanism for NF’s depression-reduction effect is that of the approach-withdrawal model as related to not only the asymmetrical activation of the frontal regions but also the hypoactivity of the amygdala. Future research might uncover other possible explanations for NF’s observed efficacy as a means of reducing depression. The findings of the study provide some support for the utilization of NF as either a complement to the pharmaceutical treatment of depression or, given its effect size, a standalone therapy. However, because NF research base is immature in comparison to the research base on pharmaceutical antidepressants, additional analysis remains necessary.

Traumatic brain injury (TBI) creates a variety of sequelae such as aphasia that can be highly challenging for clinicians when developing rehabilitation interventions. Therefore, the present study aimed to investigate the effectiveness of LORETA z -score neurofeedback (LZNFB) on language performance for a 21-year-old male suffering from aphasia following TBI. To this end, LZNFB was applied while focusing on the language network for 15 sessions. The study used an experimental design with a pre–post comparison. Baseline and posttreatment comparisons were made on qEEG/LORETA metrics, aphasia symptoms, working memory, and attention. The results indicated clinical improvements in language, working memory, and attention performances after 15 sessions of LZNFB. Our findings suggest that LZNFB may have the potential to aid language performance among those with TBI.

Introduction: Neuromodulation has been used for walking difficulty as a therapeutic approach and, as transcutaneous spinal direct current stimulation (TsDCS) is emerging as a novel tool for patients with neurological disorders when combined with transcutaneous direct current stimulation (tDCS) and/or gait training, it seems to have a promising effect; therefore, a systematic review may provide a better insight into the efficacy of the results. This systematic review aims to assess the effects of TsDCS when applied in combination with different therapies in neurological disorder patients . Methods : Databases (Pubmed, CENTRAL, and Web of Science) were used for searching studies since inception. With the guidance of reviewers, one author extracted data. Two independent reviewers assessed qualities of the randomized controlled trials (RCTs). Results : Five studies from an initial yield of 256 studies met the inclusion criteria. TsDCS might improve walking capacity when combined with tDCS and/or gait training in stroke (TsDCS with gait training and tDCS), cerebral palsy (tDCS with gait training), and cerebellar ataxia (TsDCS with tDCS). Conclusion: The result suggests that more studies are needed for concluding the therapeutic potential. Future studies should emphasize standard stimulation protocol and determining its efficacy in other outcome parameters of gait and in patients with different neurological disorders.
