Abstract

The aim of this study was firstly to identify alpha band EEG sources playing a functional role in the performance differences
between elite and amateur table tennis players use of visuo-spatial cues to guide response selection. EEG was recorded from 206 elite and amateur table tennis athletes from across the International Table Tennis Federation. EEG was obtained during eyes closed. (EC) and eyes open rest (EO) and during a 4-minute video task (VT). The VT was filmed from the player’s perspective to simulate match-play against a top 100 world ranked player. Participants imagined playing against the on-screen player. Players also completed a visuo-spatially cued version of the Go-NoGo continuous performance task (vsCPT). eLORETA compared EEG source activity between an age and gender matched sample of 16 elite and 16 amateur players. Activity at maximal source differences was then correlated with behavioural vsCPT performance measures. EEG source differences between elite and amateur players reached a maximum between 10.50 and 11.75 Hz (upper alpha) in the VT condition with loci in right BA6 (supplementary motor area, sensory selection for motor control) and right BA13 (insula cortex, salience detection). Source activity estimates correlated significantly with superior processing speed and perceptual sensitivity under increased processing demands on the vsCPT. Upper alpha synchronisation in right BA6 and right BA13 when actively processing an opponents’ match specific motion is greater in elite than amateur players and indicates superior visuo-spatial guided response selection.

Cannabis: Exit Drug to Neurotherapy

  1. Department of Neurobiology and Behavior, University of California Irvine, Irvine, CA, United States.
  2. Department of Electrical & Electronic Engineering, University of Jeddah, Jeddah, Saudi Arabia.

Abstract

This article reviews the use of cannabis for therapeutic purpose. Cannabis or marijuana had been used as a medicine in ancient China, but the illicit use of substance was stigmatized under the United Nations’ single convention on narcotic drugs. Researchers have conducted limited preclinical and clinical studies using medical marijuana, mainly as curative for memory impairment, or exit drug for substance abuse cases. The use of Cannabis for Therapeutic Purposes (CTP) in several neurological disorders is also discussed together with respective details. Finally, the similarity of CTP objectives with neurofeedback, and future research recommendations are proposed. The information presented in this article shows potential and scope of CTP with complete references.

Keywords: Cannabis, Exit Drug, Neurotherapy, therapeutic, medicine, CTP, neurofeedback, severe pain relief.

Abstract

Studies have found that optimizing course contents or lecture materials according to student’s interest could improve learning outcomes. In this work, we advocate the use of Electroencephalogram (EEG) as a modality to qualify student’s interest based on their respective brain activities. An EEG-based detection of interest in real classroom environment using Approximate Entropy (ApEn) is proposed. The method involved the use of Artificial Neural Networks (ANN) to discriminate the EEG data as relevant to either high or low situational interest. The qualitative assessment was performed by Personal Interest (PI), Situational interest (SI) questionnaires and knowledge tests which were considered as ground truth for the classifications. An accuracy of 100% and R2=0.996 was achieved in classifying 17 students as high SI or low SI. The results show that the proposed features could be used to differentiate brain activities based on student’s interest.

Keywords: Situational interest, EEG, classroom, Approximate Entropy and ANN.

EEG Neurofeedback Training for Mental Health Issues of Prisoners

  1. Department of Psychology, CHRIST (Deemed to be University), Hosur Road, Bengaluru – 560029, India.

Abstract

The EEG neurofeedback training is an upcoming intervention concerning many disorders such as Attention-Deficit/Hyperactivity
Disorder, Schizophrenia and Depression as well. The main aim of this review was to study the efficacy of this intervention on a vulnerable population like prisoners. Papers for this review were selected from established databases like PubMed, ProQuest, and ScienceDirect among many. The use of neurofeedback in the forensic psychiatric setting did not show a healthy level of applicability as expected. The main reasons for this were the variations in the sample characteristics between the studies, along with the motivation of the prisoners as well. The prison setting also delayed and interfered with the training and could also be alluded to its apparent difficulty in the application of this treatment. There are a small number of studies with even smaller samples in a population that is difficult to engage. These conditions have led to inconclusive results in most cases. There is scope for improvement, and this is an upcoming area of research. Future directions are also discussed.

Abstract

Environmental toxins are rapidly increasing as more new chemicals are synthesised and applied in agriculture, nutrition and industry including conventional and unconventional mining exploration. In the coal seam gas (CSG) exploration industry, fracking or fracturing and venting are common methods of extraction where several hundred known and unknown chemicals are used or released from the ground during the mining and venting process. Chemicals associated with fracking can lead to headaches and migraine, stress and anxiety, toxic encephalopathy as well as dizziness/balance problems and seizures. Quick and accurate as well as economical diagnostic tools are required for confirming neurological disease or toxic encephalopathy. Quantitative electroencephalography (qEEG) is one such tool for obtaining baseline data that may be associated with toxic encephalopathy. Characteristic EEG findings from the literature are focal or generalised slowing in the delta and theta frequencies or fast beta rhythms indicative of diffuse or focal cerebral structural damage and dysfunction. This paper discusses some of the common chemicals associated with CSG mining and associated EEG findings.

The Efficacy of Neurofeedback and Traditional Therapies with Autism Spectrum Disorder in a Clinic Setting

  1. PhD (Psych), Good Start Psychology, South Australia.
  2. BPsych (Hons), Good Start Psychology, South Australia.

Abstract

The efficacy of amplitude neurofeedback (NFB) in a clinic-based setting was explored in this study using a sample of 132 participants. 96% of participants were under 21 years of age. The sample appeared to be representative of the wider autistic child population. The current study used an ex post facto, quasi-experimental design. Using a clinically meaningful measure of change, called the Goal Attainment Scale, NFB participants demonstrated moderate gains on a targeted, challenging behavior or emotional problem. These gains were equivalent to a clinical response (> 50% reduction in symptoms) in traditional research terms. The NFB group performed better in absolute terms compared with traditional therapies and with NFB combined with traditional therapies. These group differences were not significant. A number of other factors did not influence clinical outcome
(e.g., age, diagnosis, protocol type) suggesting that assessment-based NFB protocols, informed by experienced NFB practitioners, and delivered by NFB practitioners with two years’ experience or less, can translate into significant and meaningful improvements for people on the spectrum. The limitations of this study were addressed.

Abstract

Learning and memory are two related, but distinct, fundamental cognitive processes. Both of these are continuous processes over the life span. In the current article, we provide a comprehensive review of the extant literature that has focused on various factors that influence the human brain processes for learning and memory. We review several factors that have been reported as directly or indirectly influence the learning and memory processes, such as sleep, emotion, exercise, attention, intelligence, testing, rehearsal, and technology. We also examine the literature on ways to enhance cognitive abilities, including neurofeedback, improve learning and memory capabilities. We conclude with a discussion of the gaps in the literature and suggestions for future research in the field.

Keywords: Learning & memory, neurofeedback (NFB), sleep, attention, stress, emotion, intelligence, testing & rehearsal, and technology.

Treating Autism Spectrum Disorder Using Pulsed EMF Therapy: A Case Series Report

  1. Brain Therapy Centre, Adelaide, South Australia.

Abstract

Autism Spectrum Disorder (ASD) is a complex, multifaceted developmental disability and presents significant challenges for intervention. Applied Behaviour Analysis (ABA) is considered the standard of treatment for improving ASD symptoms but has limitations. Neuromodulation exists as a possible additional intervention for Autism Spectrum Disorder (ASD) that may be helpful for younger, lower functioning people. This study presents a series of 5 cases where young people with ASD were treated using transcranial pulsed electromagnetic field therapy (tPEMF). Pre- and posttreatment assessment using the Autism Treatment Evaluation Checklist (ATEC) revealed statistically significant improvements in total ATEC scores, and qualitative improvements in symptoms were also reported. Future research should focus on developing a clinical trial protocol to address the limitations of a case study methodology.

Keywords: Autism Spectrum Disorder, case study research, Autism treatment, tPEMF, tPEMF for Autism.

Neurofeedback for Psychosis

  1. MB, BS, DPM, MRCPsych, FRANZCP, School of Medicine, Western Sydney University.

Abstract

Psychosis causes major disease burden, individual, family, social and economic pain. Medications are of limited effectiveness and cause many unpleasant side effects. Technology is now allowing us to examine the organ being treated, to better personalize therapies, including neurofeedback operant conditioning. The epigenetic effects of developmental trauma in the causation of psychosis are highly significant and responsive to quantitative electroencephalography (qEEG) guided neurofeedback, with very promising results. While there are many questions to be answered, it is time to implement this therapy more widely.

EEG amplitude neurofeedback: a review of the research

  1. Neurotherapy Institute of Australasia (NIA), 55B Kooyong Road, Caulfield North, Victoria 3161, Australia.

Abstract

Studies published on neuromodulation for the past 50 years were analyzed for neuromodulation technique, research design, condition or disorder investigated and outcome. 314 relevant studies were found, involving over 9,500 research subjects. EEG amplitude neurofeedback contributed over 70% of all studies. 62 randomized controlled design studies were found (and two utilizing an ABA crossover design), and of those, over 75% involved amplitude neurofeedback. Outcomes for amplitude neurofeedback were overwhelmingly positive, as they also were for other techniques with a reasonable research base. For some neuromodulation techniques the research data is meagre, and more research is needed to confirm efficacy.

Multi-modality based diagnosis: A Way Forward

  1. Neurotherapy Institute of Australasia (NIA), 55B Kooyong Road, Caulfield North, Victoria 3161, Australia.

Abstract

The Human brain is our most complex organ and responsible for controlling all bodily functions. The brain is also implicated in many psychiatric disorders and diseases such as Dementia, Depression, Epilepsy, Parkinson, Stroke, Tumour, and so on. Researchers from different fields including Neuroscience, Neurosurgery, Psychiatry, Psychology, Pharmacology, Engineering, and Computing, are continuously working to investigate and develop novel techniques to diagnose and treat the brain’s disorders using neuroimaging modalities. Today, many different modalities are currently used such as electroencephalogram (EEG), functional magnetic resonance imaging (fMRI), functional near infrared (fNIR), Magnetoencephalography (MEG), positron emission tomography (PET), and computed tomography (CT). Each technique has its own strengths and limitations and thus is suited to a specific area of study. However, these modalities can be used simultaneously to reduce the limitations of using one technique and enhance the accuracy of disease diagnosis. Multimodality-based diagnosis will help clinicians to identify both early and accurately those individuals who are at risk of many conditions including brain tumor, tumor recurrence, and Alzheimer’s disease.

Abstract

Recent evidence points to the increasingly important role of sleep disturbance in ADHD. Circadian phase delay, resulting in delayed sleep onset, has been consistently described with causality implied for a large subgroup with Attention Deficit Hyperactivity Disorder (ADHD). The likelihood of varied and numerous causations in ADHD, the high prevalence of sleep disorders and the likely etiological/pathogenetic role of sleep disorders for a large subgroup with ADHD encourages a personalized medicine approach, particularly by assessing sleep and identifying biomarkers to assist in identifying subgroups which can enable a more personalized treatment. Psychostimulants are the mainstay of pharmacological treatment of ADHD, but do not assist sleep problems and can in fact exacerbate them. In a large subgroup with ADHD, psychoeducation and sleep hygiene, CBTi and chronotherapy also have an important role to play in treating ADHD symptoms associated with sleep disturbance. Neurofeedback (operant conditioning of EEG), may have specific and lasting effects on sleep, and in turn ADHD symptoms, with the effect shown to be mediated via the normalization of sleep. This review article summaries and reports on some of the accumulating evidence for the role of sleep in ADHD and outlines various methods for assessment and intervention.

QEEG AS A BASE FOR NEUROFEEDBACK TREATMENT: IS IT RELIABLE ENOUGH?

  1. CEO at BetterFly Neurofeedback, 24 Beit-El st, Tel-Aviv 6908720, Israel.

Abstract

In the last two decades, qEEG has turned from a purely research tool into an important, basic part of the work of many neurofeedback clinicians. The analysis of EEG samples requires extensive knowledge and experience, which up until a decade ago were the province of a few experts in the neurofeedback community. Unlike the deep knowledge that is required in order to analyze raw EEG, performing an FFT analysis and creating qEEG maps and graphs is computerized and relatively straight forward. This article presents examples that explain the importance of surveying the raw EEG before starting the qEEG analysis, and combining raw EGG analysis with a close reading of the qEEG report in order to perform a reliable analysisof the information and to make proper decisions regarding the treatment protocol. In this article, we will use a few different softwares and technologies, and try to illustrate the common factors and common ideas that underlie each of these technologies.

Developmental Trauma, LENS and Neural Regulation: Brain and Body

  1. Ph.D. Private Practice206A – 1571 Bellevue Avenue, West Vancouver, BCV7V1A6, Canada.

Abstract

Individuals with a history of Developmental Trauma often have complex histories and symptom patterns that do not respond easily to therapeutic interventions. The addition of LENS Neurofeedback and its integration with other psychotherapeutic interventions for Developmental Trauma are discussed. LENS is unique in the field of neurofeedback in that it applies the concept of neural regulation not only to the brain but also to the body, reflecting both Top-down and Bottom-up interventions. Such an integrated body mind approach dovetails uniquely with other information processing interventions. Case studies of individuals that had previously had not responded to other interventions are presented who benefitted from the integration of LENS neurofeedback and associated neural regulation approaches into standard trauma treatment interventions. It is suggested that individuals with a history of Developmental Trauma benefit from the addition to LENS neurofeedback by directly intervening at the level of the electrical or frequency domain.
