Frontiers in Psychiatry, 2022 BackgroundMajor depressive disorder (MDD) is associated with dysfunction of the reward system. As an important node in the reward system, the resting-state functional connectivity of the nucleus accumbens (NAc) is related to the etiology of MDD. However,

Proceedings of the National Academy of Sciences of the United States of America, 1992 We report that visual stimulation produces an easily detectable (5-20%) transient increase in the intensity of water proton magnetic resonance signals in human primary visual cortex in gradient echo images at 4-T magnetic-field strength.

Methodology of magnetic resonance imaging [PDF]
Quarterly Reviews of Biophysics, 1987 AbstractA survey of magnetic resonance imaging techniques is presented. Emphasis is put on the basic types of measurement procedures rather than, discussing all variants proposed so far. The general experimental procedure consists of two phases, the preconditioning period and the image formation period.

The magnetic-resonance force microscope: a new tool for high-resolution, 3-D, subsurface scanned probe imaging [PDF]
, 2003 The magnetic-resonance force microscope (MRFM) is a novel scanned probe instrument which combines the three-dimensional (3-D) imaging capabilities of magnetic-resonance imaging with the high sensitivity and resolution of atomic-force microscopy.

Tracing of Neuronal Connections in the Human Brain by Magnetic Resonance Imaging in vivo [PDF]
, 1990 Axon degeneration after disruption of fibre tracts in the mammalian nervous system is accompanied by myelin breakdown which leads to changes in its magnetic resonance properties.

Cardiovascular magnetic resonance imaging
Medicine, 2010 MRI (magnetic resonance imaging) uses the magnetic properties of the hydrogen nucleus, radio waves and powerful magnets to provide high-quality still and cine images of the cardiovascular system, with and without the use of exogenous contrast (gadolinium).

Linear magnetic resonance imaging measurements of the hippocampal formation differ in young versus old dogs [PDF]
, 2019 Age-related hippocampal formation (HF) atrophy has been documented on MRI studies using volumetric analysis and visual rating scales.This retrospective cross-sectional study aimed to compare linear MRI measurements of the HF between young (1–3 years) and
