Objectives: Regarding the importance of craving in the persistence of addiction, this study has been carried out with the aim of determining the differences between the two distinguishable groups of heroin addicts: responders and non-responders to craving cues. Method: In a case-control study, 26 male intravenous heroin addicts were selected from among non-treatment seeker abusing addicts in Te...
Brain injuries are significant disorders affecting human life. Some of these damages can be completely eliminated by methods such as drug therapy. On the other hand, there is no known permanent treatment for caused diseases Alzheimer, Autism spectrum disorder (ASD), Multiple sclerosis and Parkinson. Treatments aimed at slowing progression disease generally applied in types disorders. For this r...
Abstract Introduction: Concurrent TMS/fMRI has become a promising technique for investigating the acute effects of rTMS on brain. However, image quality in concurrent may still have its limitations. In this study, we aimed to explore data before concluding findings from state-of-the-art setup ensure imaging was sufficient analysis. Methods: Nineteen healthy participants participated study. firs...
Introduction: Functional MRI methods have been used to study sensorimotor processing in the Spinal cord. However, these techniques confront unwanted contributions to the measured signal from the physiological fluctuations. For the spinal cord imaging, most of the challenges are consequences of cardiac and respiratory movement artifacts that are considered as significant sources of noise, especi...
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...
کنترل سلامت انسانها در دنیای کنونی و تشخیصهای پزشکی، بدون استفاده از تصاویر گرفته شده از اندامها و بافتهای بدن قابل تصور نیست. در این میان، روشهایی که مبتنی بر اخذ تصویر از مغز انسان هستند از اهمیت ویژه ای برخوردارند زیرا مغز بعنوان مرکز تصمیم گیری و کنترل فعالیتهای خودآگاه و ناخودآگاه انسان عمل می کند و عملکرد نامناسب آن عامل بروز بسیاری از ناتوانیهای جسمی و ناهنجاریهای رفتاری و روحی می باشد. ...
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...
