Developing an EEG-fNIRS Neurofeedback Application for Brain Training for Autistic Children Altered brain function is a hallmark feature of autism spectrum disorder and underpins cognitive, emotional, and social differences in autistic individuals. Unfortunately, in Hong Kong, the brain health of autistic children has been largely neglected; technological methods that directly alter autistic brain functioning also remain lacking. These lead to suboptimal outcomes for many autistic children. In the West, neurofeedback training using either electroencephalography (EEG) or functional near-infrared spectroscopy (fNIRS) has been shown to bring promising cognitive, emotional, and behavioral benefits to some neuropsychiatric disorders, including autism. Importantly, these technologies are relatively low-cost and user-friendly, making them ideal for remediating brain dysfunction. Because EEG and fNIRS capture different aspects of brain activity, integrating them can arguably augment the therapeutic effects of neurofeedback training. Here, we propose a proof-of-concept project to make innovations in developing a versatile, currently nonexistent combined EEG-fNIRS neurofeedback application to offer synergistic brain training for autistic children. Using this application, we will then evaluate the feasibility and efficacy of combined EEG-fNIRS neurofeedback training for improving functioning and symptoms in these children. This project will enable a direct, comprehensive technology-based neurorehabilitation for autistic children, which can help reduce healthcare costs and feed the medical technology industry in Hong Kong.

Temporal dynamics of resolving multiple concurrent conflicts: A pilot developmental ERP study In everyday life, we often encounter situations in which various types of conflicts need to be resolved at the same time. Currently, much is known about conflict resolution and its neural processing under one single conflict. However, the neural mechanisms underlying conflict resolution under multiple concurrent conflicts remain poorly known, and whether there are developmental differences in the independence of different conflict processes also is still elusive. These prevent the development of effective intervention strategies for individuals with difficulty resolving conflicts. The aim of this study is to examine the temporal dynamics and developmental differences associated with conflict resolution under multiple concurrent conflicts using the event-related potential (ERP) technique. Children aged 8–12, adolescents aged 13–17, and young adults aged 18–25 will perform several combined conflict tasks, each with three conflict types, while their electroencephalography is being recorded. Different co-occurring conflict types are expected to modulate ERP components differently, suggesting that multiple, independent conflict-driven control mechanisms exist in the brain. In addition, these patterns are expected to be evident in young adults but not in children. The findings will inform strategies and facilitate identification of the best timing for intervening with conflict resolution under multiple concurrent conflicts.

Understanding the role of the frontoparietal network in the development of executive function in children and adolescents with autism spectrum disorder Executive function (EF) skills (i.e., attentional shifting, cognitive/behavioral inhibition, and working memory updating) play an essential role in social competence and behavioral flexibility. In autism spectrum disorder (ASD), which is characterized by social communication impairment and restricted and stereotyped behavior, an improved understanding of EF is essential for developing effective treatments for ASD individuals. While considerable evidence suggests that EF impairments are associated with ASD, the reported findings on the subject have been mixed. Several cross-sectional studies, including our pilot study, have linked older age with worse EF relative to age-expected levels in ASD. However, details about the exact neural mechanisms underlying this phenomenon are currently lacking, preventing the development of effective neurological rehabilitation as a means to improve EF development in ASD. The lateral frontoparietal network, comprising the dorsolateral prefrontal and inferior parietal cortices, has long been implicated in EF. This network undergoes continued functional development characterized by dissociable increases in local activation and long-range connectivity during EF tasks throughout childhood and adolescence. This project is aimed to build on our pilot study’s results, examining whether reduced developmental improvements in frontoparietal function in ASD individuals compared to typically developing (TD) individuals underlie these individuals’ differences in developmental changes in EF. The findings will determine whether interventions targeting the frontoparietal network represent a promising approach to remediating the underdevelopment of EF in ASD individuals. We will recruit 90 ASD and 90 demographically matched TD individuals aged 8–17 years. Each will complete nine EF tasks, three each for shifting, inhibition, and updating.Functional near-infrared spectroscopy (fNIRS) will be used to measure frontoparietal activation and connectivity during some EF tasks. We hypothesize that (1) older age is associated with a larger group difference (TD > ASD) in each core EF skill, (2) older age is associated with greater group differences (TD > ASD) in frontoparietal activation and connectivity during EF tasks, and (3) reduced developmental changes in frontoparietal activation and connectivity in ASD underlie the difference in developmental changes in EF between TD and ASD individuals. This ASD project is novel in that we (1) perform a systematic assessment of EF, evaluating each component through multiple tasks; (2) employ two orthogonal measures (i.e., activation level and functional connectivity) to give a full picture of frontoparietal hemodynamics; and (3) elucidate the currently unknown neural mechanisms underlying the difference in developmental changes in EF between ASD and TD individuals.
