Nowadays, many people worldwide suffer from brain disorders, and their health is in danger. So far, numerous methods have been proposed for the diagnosis of Schizophrenia (SZ) attention deficit hyperactivity disorder (ADHD), among which functional magnetic resonance imaging (fMRI) modalities are known as a popular method physicians. This paper presents an SZ ADHD intelligent detection resting-s...

Introduction: The purpose of multimodal and co-registration In MR Neuroimaging is to fuse two or more sets images (T1, T2, fMRI, DTI, pMRI, …) for combining the different information into a composite correlated data set in order to visualization, re-alignment and generating transform to functional Matrix. Multimodal registration and motion correction in spinal cord MR Neuroimag...

Billions of people play Internet games and some them may develop gaming disorder (IGD), yet the differences between IGD non-disordered but heavy use behavior remain unclear. We used multiple behaviors multimodal functional magnetic resonance imaging (fMRI) to examine specificity impulse control differentiate from use. One hundred sixty subjects, including patients with (PIGD), participants (NIG...

We propose a novel matrix autoencoder to map functional connectomes from resting state fMRI (rs-fMRI) structural Diffusion Tensor Imaging (DTI), as guided by subject-level phenotypic measures. Our specialized infers low dimensional manifold embedding for the rs-fMRI correlation matrices that mimics canonical outer-product decomposition. The is simultaneously used reconstruct DTI tractography vi...

Multimodal functional near-infrared spectroscopy–functional magnetic resonance imaging (fNIRS–fMRI) studies have been highly beneficial for both the fNIRS and fMRI field as, example, they shed light on underlying mechanism of each method. However, several noise sources exist in methods. Motion artifact removal is an important preprocessing step analysis. Several manual motion–artifact methods d...

Abstract Background Juvenile myoclonic epilepsy (JME) is the most common syndrome of idiopathic generalized epilepsy. Although resting-state functional magnetic resonance imaging (rs-fMRI) studies have found thalamocortical circuit dysfunction in patients with JME, pathophysiological mechanism JME remains unclear. In this study, we used three complementary parameters rs-fMRI to investigate aber...

در این مقاله، به بررسی اثر پارامترهای کاری گوناگون بر شکل تپ‌های خروجی یک لیزر 2CO تپی فشار اتمسفری پرتکرار دست‌ساز (با آهنگ تکرار تا kHz 1) پرداخته شده است. راستا، عوامل گوناگونی هم­چون: نسبت گاز 2N، He و بازتابندگی آینه جلویی تغییر داده شدند انرژی گسیلی هر از حالت‌ها ثبت مشخصه‌یابی شدند. نشان شد که با گازهای 2N He، می‌توان دیرش زمانی میخه دنباله‌ی تپ‌ها را بازه‌ی ns 140-95 µs 5/3-5/1 تنظیم نم...

Neuronal brain activity is assumed to be reflected by blood level oxygenation levels, also known as BOLD signal, measured with fMRI. A scan of the literature points both oxygen and carbon dioxide levels effects on The roles (O2 ; hypoxia/hypoxemia, hyperoxia) (CO2 hypocapnia, hypercapnia) in neuronal signal are complex still under investigation [1,2]. Inspiration while varying O2 CO2 air have b...
