Chronic fatigue: Brain matters

Date: Nov 1, 2014

Author: David Bradley

US researchers have discovered, using magnetic resonance imaging, that the brains of patients with chronic fatigue syndrome have diminished white matter and white matter abnormalities in the right hemisphere.

Journal Highlight: Functional magnetic resonance imaging of story listening in adolescents and young adults with Down syndrome: evidence for atypical neurodevelopment

Date: Oct 27, 2014

Author: spectroscopyNOW

Functional magnetic resonance imaging has been used to compare activation during language processing in young adults with Down syndrome to that in typically developing comparison groups matched for chronological age or mental age.

Tackling Tourette syndrome: Therapeutic clues from MRI

Date: Oct 1, 2014

Author: David Bradley

Magnetic resonance imaging scans can show the patterns of neurotransmitters in people with Tourette syndrome that are associated with particular brain activity. The details could lead to new therapeutic targets for disorder.

Journal Highlight: Interrelations of muscle functional MRI, diffusion-weighted MRI and 31P-MRS in exercised lower back muscles

Date: Sep 22, 2014

Author: spectroscopyNOW

Exercise-induced changes of transverse proton relaxation time, tissue perfusion and metabolic turnover were investigated in the lower back muscles of volunteers by applying muscle functional MRI and diffusion-weighted imaging before and after exercise as well as dynamic 31P-MRS during exercise.

Extended childhood: Brain volume

Date: Sep 1, 2014

Author: David Bradley

Pooled data from positron emission tomography (PET) and magnetic resonance imaging (MRI) scans of children's brains suggests that the brain increases in overall volume rapidly and using a large proportion of ingested nutrients during the period of lowest body growth in children at age about 4 years. The finding hints at a possible explanation as to why humans grow so slowly and have such a long childhood compared with most other mammals.

Journal Highlight: Iron deposits in post-mortem brains of patients with neurodegenerative and cerebrovascular diseases: a semi-quantitative 7.0 T magnetic resonance imaging study

Date: Aug 25, 2014

Author: spectroscopyNOW

The iron content in post-mortem brains with different neurodegenerative and cerebrovascular diseases has been investigated by T2*-weighted gradient-echo 7.0 T magnetic resonance imaging.

Anxiety: The pleasure principle

Date: Aug 1, 2014

Author: David Bradley

Functional magnetic resonances imaging (fMRI) reveals activity in two different regions of the brain of people given a choice between two or more equally positive outcomes that give rise to both pleasure and anxiety simultaneously.

Journal Highlight: MRI by steering resonance through space

Date: Jul 21, 2014

Author: spectroscopyNOW

A technique called steering resonance over the object (STEREO) has been developed to excite magnetic resonance signals locally to demonstrate the feasibility of MRI with multidimensional spatiotemporal-encoding that can compensate extreme field inhomogeneity.

Here comes the flood: Functional memory insights

Date: Jul 1, 2014

Author: David Bradley

Many people are familiar with how a simple trigger, a scent, a colour, a piece of music, a photograph can bring back a "flood" of disparate memories all at once. There are mathematical theories called global similarity models that attempt to explain this phenomenon. Now, a functional magnetic resonance study (fMRI) on memory and categorization has put this mathematical model on a firm neurobiological footing for the first time.

Journal Highlight: Does magnetic resonance imaging predict future low back pain? A systematic review

Date: Jun 23, 2014

Author: spectroscopyNOW

MEDLINE, CINAHL and EMBASE databases were searched in a systematic review of the ability of MRI studies of the lumbar spine to predict future lower back pain.
