Medical images modality classification using multi-scale dictionary learning [PDF]

open access: yes, 2014
In this paper, we proposed a method for classification of medical images captured by different sensors (modalities) based on multi-scale wavelet representation using dictionary learning.

Complex networks: new trends for the analysis of brain connectivity [PDF]

open access: yes, 2010
Today, the human brain can be studied as a whole. Electroencephalography, magnetoencephalography, or functional magnetic resonance imaging techniques provide functional connectivity patterns between different brain areas, and during different ...

Decreased Intrinsic Neural Timescales in Mesial Temporal Lobe Epilepsy

open access: yesFrontiers in Human Neuroscience, 2021
It is well established that epilepsy is characterized by the destruction of the information capacity of brain network and the interference with information processing in regions outside the epileptogenic focus.

Learning and comparing functional connectomes across subjects [PDF]

open access: yes, 2013
Functional connectomes capture brain interactions via synchronized fluctuations in the functional magnetic resonance imaging signal. If measured during rest, they map the intrinsic functional architecture of the brain.

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.

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.

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.

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.
