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.

Static and temporal dynamic changes of intrinsic brain activity in early-onset and adult-onset schizophrenia: a fMRI study of interaction effects

open access: yesFrontiers in Neurology
BackgroundSchizophrenia is characterized by altered static and dynamic spontaneous brain activity. However, the conclusions regarding this are inconsistent.

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.

Altered hippocampal function in major depression despite intact structure and resting perfusion [PDF]

open access: yes, 2016
Background: Hippocampal volume reductions in major depression have been frequently reported. However, evidence for functional abnormalities in the same region in depression has been less clear.

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

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 ...

Imaging memory in temporal lobe epilepsy: predicting the effects of temporal lobe resection [PDF]

open access: yes, 2010
Functional magnetic resonance imaging can demonstrate the functional anatomy of cognitive processes. In patients with refractory temporal lobe epilepsy, evaluation of preoperative verbal and visual memory function is important as anterior temporal lobe ...

Asymmetry of parietal interhemispheric connections in humans [PDF]

open access: yes, 2011
Visuospatial abilities are preferentially mediated by the right hemisphere. Although this asymmetry of function is thought to be due to an unbalanced interaction between cerebral hemispheres, the underlying neurophysiological substrate is still largely ...
