Altered intrinsic neural activity and its molecular analyses in first-episode schizophrenia with auditory verbal hallucinations

open access: yesFrontiers in Neuroscience
BackgroundAuditory verbal hallucinations (AVHs) are one of the signature positive symptoms of schizophrenia, affecting a substantial portion of patients with schizophrenia.

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.

Optically Detected Magnetic Resonance Imaging [PDF]

open access: yes, 2014
Optically detected magnetic resonance (ODMR) provides ultrasensitive means to detect and image a small number of electron and nuclear spins, down to the single spin level with nanoscale resolution. Despite the significant recent progress in this field, it has never been combined with the power of pulsed magnetic resonance imaging (MRI) techniques. Here,

More Than Just Statics: Temporal Dynamic Changes in Inter- and Intrahemispheric Functional Connectivity in First-Episode, Drug-Naive Patients With Major Depressive Disorder

open access: yesFrontiers in Human Neuroscience, 2022
Several functional magnetic resonance imaging (fMRI) studies have demonstrated abnormalities in static intra- and interhemispheric functional connectivity among diverse brain regions in patients with major depressive disorder (MDD).

Functional Magnetic Resonance Imaging

open access: yes, 2006
Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) is a powerful approach to defining activity in the healthy and diseased human brain. BOLD fMRI detects local increases in relative blood oxygenation that are most probably a direct consequence of neurotransmitter action and thus reflect local neuronal signalling.

Men fear other men most: Gender specific brain activations in perceiving threat from dynamic faces and bodies. An fMRI study. [PDF]

open access: yes, 2010
We report a functional magnetic resonance imaging experiment showing different activation patterns as a function of threatening signals from facial or bodily expressions and these differed between male and female participants as a function of male and ...

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 ...

Variation in the oxytocin receptor gene is associated with behavioral and neural correlates of empathic accuracy

open access: yesFrontiers in Behavioral Neuroscience, 2014
The neuromodulators oxytocin and serotonin have been implicated in regulating affective processes underlying empathy. Understanding this dependency, however, has been limited by a lack of objective metrics for measuring empathic performance.

Travelling Wave Magnetic Resonance Imaging at 3 Tesla [PDF]

open access: yes, 2013
Waveguides have been successfully used to generate magnetic resonance images at 7 T with whole-body systems. The bore limits the magnetic resonance signal transmitted because its specific cut-off frequency is greater than the majority of resonant frequencies.
