Resting-state functional connectivity alterations in intermet gaming disorder: A fMRI study combining voxel-based morphometry meta-analysis

open access: yesBrain Research Bulletin
Background: Internet gaming disorder (IGD) is a behavioral addiction, as revealed by previous neuroimaging studies on gray matter volume alterations and functional connectivity abnormalities that patients with internet gaming disorder have.

Functional imaging of plants: A nuclear magnetic resonance study of a cucumber plant

open access: yes, 2002
Functional magnetic resonance imaging was used to study transients of biophysical parameters in a cucumber plant in response to environmental changes. Detailed flow imaging experiments showed the location of xylem and phloem in the stem and the response ...

A bilateral cortico-bulbar network associated with breath holding in humans, determined by functional magnetic resonance imaging [PDF]

open access: yes, 2008
Few tasks are simpler to perform than a breath hold; however, the neural basis underlying this voluntary inhibitory behaviour, which must suppress spontaneous respiratory motor output, is unknown.

Alternations in Dynamic and Static Functional Connectivity Density in Chronic Smokers

open access: yesFrontiers in Psychiatry, 2022
Previous studies have implicated abnormal functional coordination in brain regions of smokers. Neuroimaging studies demonstrated alternations in brain connectivity by using the resting-state functional connectivity (rsFC) method which arbitrarily chooses

Functional Magnetic Resonance Imaging Methods [PDF]

open access: yesNeuropsychology Review, 2015
Since its inception in 1992, Functional Magnetic Resonance Imaging (fMRI) has become an indispensible tool for studying cognition in both the healthy and dysfunctional brain. FMRI monitors changes in the oxygenation of brain tissue resulting from altered metabolism consequent to a task-based evoked neural response or from spontaneous fluctuations in ...

Boosting BOLD fMRI by K-Space density weighted echo planar imaging [PDF]

open access: yes, 2013
Functional magnetic resonance imaging (fMRI) has become a powerful and influential method to non-invasively study neuronal brain activity. For this purpose, the blood oxygenation level-dependent (BOLD) effect is most widely used. T2* weighted echo planar

Weight Status Modulated Brain Regional Homogeneity in Long-Term Male Smokers

open access: yesFrontiers in Psychiatry, 2022
BackgroundTobacco smoking and being overweight could lead to adverse health effects, which remain an important public health problem worldwide. Research indicates that overlapping pathophysiology may contribute to tobacco addiction and being overweight ...

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Rapid magnetic resonance tissue relaxometry in the steady state [PDF]

open access: yes, 2015
Longitudinal (T1) and transverse (T2) relaxation are the most fundamental physical processes governing the signal intensity and the soft tissue contrast in magnetic resonance imaging (MRI).

Abnormal Granger causal connectivity based on altered gray matter volume and associated neurotransmitters of adolescents with internet gaming disorder revealed by a multimodal neuroimaging study

open access: yesDevelopmental Cognitive Neuroscience
Although prior studies have revealed alterations in gray matter volume (GMV) among individuals with internet gaming disorder (IGD). The brain's multifaceted functions hinge crucially on the intricate connections and communication among distinct regions ...
