Acoustic, psychophysical, and neuroimaging measurements of the effectiveness of active cancellation during auditory functional magnetic resonance imaging [PDF]

open access: yes, 2009
Functional magnetic resonance imaging (fMRI) is one of the principal neuroimaging techniques for studying human audition, but it generates an intense background sound which hinders listening performance and confounds measures of the auditory response ...

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.

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.
