Altered functional connectivity within the primary visual networks and neurotransmitter activity in male smokers: A group ICA study

open access: yesBrain Research Bulletin
Smoking puts patients at high risk for cognitive and psychiatric disorders. The aim of this study was to explore the effects of nicotine use on primary visual network (PVN) and its association with neurotransmitters.

Functional Magnetic Resonance Imaging in Pediatrics [PDF]

open access: yesNeuropediatrics, 2003
Functional magnetic resonance imaging (fMRI) allows non-invasive assessment of human brain function in vivo by detecting blood flow differences. In this review, we want to illustrate the background and different aspects of performing functional magnetic resonance imaging (fMRI) in the pediatric age group.

Explore the effects of overweight and smoking on spontaneous brain activity: Independent and reverse

open access: yesFrontiers in Neuroscience, 2022
Accumulating evidence suggested that overweight and smoking often co-exist. However, current neuroimaging researches have almost always studied smoking or overweight status separately.

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.

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
