Meta-analysis of structural and functional alterations of brain in patients with attention-deficit/hyperactivity disorder

open access: yesFrontiers in Psychiatry, 2023
BackgroundA large and growing body of neuroimaging research has concentrated on patients with attention-deficit/hyperactivity disorder (ADHD), but with inconsistent conclusions.

Exploring T*2 decay : new methods for short echo time imaging and fat-water quantification [PDF]

open access: yes, 2013
The major advantage of magnetic resonance imaging (MRI) over other imaging modalities like computed tomography (CT) is that it does not utilize ionizing radiation.

Integrative Functional, Molecular, and Transcriptomic Analyses of Altered Intrinsic Timescale Gradient in Depression

open access: yesFrontiers in Neuroscience, 2022
The pathophysiology and pharmacology of depression are hypothesized to be related to the imbalance of excitation–inhibition that gives rise to hierarchical dynamics (or intrinsic timescale gradient), further supporting a hierarchy of cortical functions ...

Molecular magnetic resonance imaging of brain–immune interactions [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2014
Although the blood-brain barrier (BBB) was thought to protect the brain from the effects of the immune system, immune cells can nevertheless migrate from the blood to the brain, either as a cause or as a consequence of central nervous system (CNS) diseases, thus contributing to their evolution and outcome.

Porphyrin-magnetite nanoconjugates for biological imaging [PDF]

open access: yes, 2011
<p>Background: The use of silica coated magnetic nanoparticles as contrast agents has resulted in the production of highly stable, non-toxic solutions that can be manipulated via an external magnetic field.

Impaired large-scale cortico–hippocampal network connectivity, including the anterior temporal and posterior medial systems, and its associations with cognition in patients with first-episode schizophrenia

open access: yesFrontiers in Neuroscience, 2023
Background and objectiveThe cortico–hippocampal network is an emerging neural framework with striking evidence that it supports cognition in humans, especially memory; this network includes the anterior temporal (AT) system, the posterior medial (PM ...
