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...

Background: Functional neuroimaging can provide pathophysiological information in perinatal asphyxia (PA). However, fundamental unresolved questions remain related to the influence of neurovascular coupling (NVC) maturation on functional responses early development. We aimed probe feasibility and compare multiple sensory stimulations newborns with PA using magnetic resonance imaging (fMRI) near...

In honor of Dr. James S. Hyde’s contributions to the field of functional magnetic resonance imaging (fMRI) and resting-state functional connectivity magnetic resonance imaging (rs-fcMRI), we, the current and former graduate students, postdoctoral researchers, faculty colleagues, and academic friends, dedicate this two-issue special Festschrift publication series to him. We begin this publicatio...

background hepatic fibrosis is a typical complication of chronic liver diseases resulting in cirrhosis that remains a major public health problem worldwide. liver biopsy is currently the gold standard for diagnosing and staging hepatic fibrosis. percutaneous liver biopsy; however, is an invasive procedure with risks of complications. therefore, there is need for alternative non-invasive techniq...

Neuroimaging comprises a set of tools, which include different types of magnetic resonance imaging such as functional magnetic resonance imaging (fMRI), Magnetic Resonance Spectroscopy (MRS), Arterial Spin Labeling (ASL), and radiotracer imaging such as positron emission tomography and single photon emission computed tomography. The focus of this review is to address the question whether fMRI c...

background: alzheimer's disease is the most common form of dementia which is still difficult to be differentiated from other types of brain disorders. moreover, mild cognitive impairment refers to the presence of cognitive impairments that is not severe enough to meet the criteria of alzheimer's, and its diagnosis in early stages is so critical. there is currently no distinct method available f...

 The attempt to find out if someone is telling a lie has been of human's interest. One of the techniques which is believed to be efficient in future is fMRI (functional Magnetic Resonance Imaging), using which the changes of regional blood flow during the designed paradigm can be recorded. This method has been considered as a better technique for studying lie and deception. For investigating th...

The combination of optogenetics and functional magnetic resonance imaging (fMRI) is referred to as opto-fMRI. Optogenetics utilises genetic engineering to introduce light sensitive actuator proteins into cells. Functional MRI (fMRI) is a specialist form of magnetic resonance imaging concerned with imaging changes in blood flow and oxygenation, linked to regional variation in metabolic activity,...

Magnetic resonance (MR) acoustic scanner noise may negatively affect the performance of functional magnetic resonance imaging (fMRI), a problem that worsens at the higher field strengths proposed to enhance fMRI. We present an overview of the current knowledge on the effects of confounding acoustic MR noise in fMRI experiments. The principles and effectiveness of various methods to reduce acous...

Functional magnetic resonance imaging (fMRI) data provides information concerning activity in the brain and particular interactions between regions. Resting state fMRI is widely used for inferring connectivities which are not due to external factors. As such analyzes strongly rely on stationarity, change point procedures can be applied order detect possible deviations from this crucial assumpti...
