Both resting state fMRI (R-fMRI) and task-based fMRI (T-fMRI) have been widely used to study the functional activities of the human brain during task-free and task-performance periods, respectively. However, due to the difficulty in strictly controlling the participating subject's mental status and their cognitive behaviors during fMRI scans, it has been very challenging to tell whether or not ...

Considering that functional magnetic resonance imaging (fMRI) signals from multiple subjects (MS) can be represented together as a sum of common and distinct rank-1 matrices, new MS dictionary learning (DL) algorithm named sparse group (common + distinct) bases (sgBACES) is proposed. Unlike existing MS-DL algorithms ignore fMRI data’s prior information, it formulated penalized plus const...

Blood oxygen contrast-functional magnetic resonance imaging (fMRI) signals are a convolution of neural and vascular components. Several studies indicate that task-related (T-fMRI) or resting-state (R-fMRI) responses linearly relate to hypercapnic task responses. Based on the linearity of R-fMRI and T-fMRI with hypercapnia demonstrated by different groups using different study designs, we hypoth...

به طور کلی، هر سلول طبیعی بدن انسان، که مشتمل بر قسمت‌های مختلفی همچون هسته، غشاء سلولی و نانوالیاف پروتئینی می‌باشد، دارای سختی استحکام مکانیکی مشخصی است. هرگونه تغییر محسوس در این استحکام، نشان از یک بیماری دارد. یکی راه‌های تشخیص بیماری‌های مختلف سرطان های سنجش میزان تغییرات رخ داده خواص آن‌ها می‌باشد. مقالۀ حاضر، مشخصات شامل مدول الاستیسیته نیروی چسبندگی Ago-1522 سلول‌های پوست محسوب می‌شود،...

The dynamic core hypothesis posits that consciousness is correlated with simultaneously integrated and differentiated assemblies of transiently synchronized brain regions. We represented time-dependent functional interactions using networks assessed the integrity by means size flexibility largest multilayer module. As a first step, we constrained parameter selection newly developed benchmark fo...

Brain stroke discovery remains one of the foremost critical investigation zones in restorative imaging. A brain can be classified into two primary categories Ischemic and Haemorrhagic. Imaging technology detects strokes early. When it comes to imaging, American College Radiology persistently overhauls its rules for imaging pathways through ACR Fittingness Criteria. There are a few prevalent met...

Using machine learning methods to estimate brain effective connectivity networks from functional magnetic resonance imaging (fMRI) data has garnered significant attention in the fields of neuroinformatics and bioinformatics. However, existing usually require retraining model for each subject, which ignores knowledge shared across subjects. In this paper, we propose a novel framework estimating ...

Pain is a subjective feeling having sensory, cognitive and emotional components. Brain regions that cognitively affectively contribute to pain sensation are the anterior cingulate cortex (ACC), insula, prefontal (PFC) default mode network (DMN). Depression anxiety may accompany they exaggerate via affective disturbance. As complementary treatment of pain, mindfulness meditation which therapeuti...
