چکیده

Background and Aim : Holding information in the brain for a while is a common process underlying most of the higher cognitive functions such as attention, working memory, decision making, mental imagery, and planned actions. Recent evidence proposed the great contribution of beta-band activity in the maintenance of the status quo. There is a massive body of evidence for the role of beta-band activity in the sensorimotor cortex, however, the association of beta-band activity in non-motor tasks across the non-motor cortex is poorly understood.Methods : To explore the different roles of beta-band activity in cognitive tasks, we will review the beta-band coupling observation in system neuroscience papers. We focused on primate electrophysiological studies (ECOG and E/MEG in human and extracellular recording in monkeys) reported the role of beta-band activity in cognitive tasks.Results : As a unique component in indigenous tasks, the beta-band activity might be a simple tool for the top-down indigenous driven signal. By categorizing different studies in this field, we will provide alternative explanations for the neural mechanism of beta-band coupling.Conclusion : Furthermore, given the role of beta-band activity in disorders, we will cover the brain stimulation protocol which can be used in cognitive rehabilitation.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
