Video nasties
Date: Apr 1, 2008
Author: David Bradley
US researchers have used functional magnetic resonance imaging (fMRI) for the first time to monitor how the brain copes with disgust while watching video nasties. They found that the grin and bear it approach does not work nearly so well as positive reappraisal of the images one is seeing.

Gender-related and age-related urinalysis of healthy subjects by NMR-based metabonomics
Date: Mar 26, 2008
Author:
NMR-based metabonomic analysis is a well-established approach to characterizing healthy and diseased states. The aim of this study was to investigate inter-individual variability in the metabolic urinary profile of a healthy population, not subjected to strict dietary limitations, by NMR-based metabonomics.

Men play, women left unrewarded
Date: Mar 1, 2008
Author: David Bradley
The latest results from functional MRI suggest a possible explanation as to why males enjoy, and even become addicted to, video games more commonly than females. Allan Reiss and colleagues at Stanford University School of Medicine have shown that one of the brain's reward centres is simply more active during video-game play in men than in women.

Fast screening of paramagnetic molecules in zebrafish embryos by MRI
Date: Feb 25, 2008
Author:
Zebrafish embryo is a well-established model used in many fields of modern experimental biology. In this paper the authors demonstrate that it provides a promising model platform for exploring fundamental MR aspects that can be used to screen and study active MR molecules before progressing to more complex living systems.

Cultural exchange
Date: Feb 1, 2008
Author: David Bradley
According to the latest results from functional magnetic resonance imaging (fMRI) studies, people from East Asian cultures use their brains differently from people immersed in American culture when solving the same visual mental tasks. The findings could have implications for understanding how culture affects behaviour.

In vivo proton magnetic resonance spectroscopy in patients with mood disorders: A technically oriented review
Date: Jan 30, 2008
Author:
Proton MR spectroscopy (1HMRS) has been extensively used among mood disorders patients. A review of some of the published literature in 1HMRS studies of mood disorders is published here in this recent paper taken from the Journal of Magnetic Resonance Imaging.

Gotta have faith
Date: Jan 3, 2008
Author: David Bradley
While many people will have completed their winter solstice festivals by now, there are many others who will still be taking part in religious celebrations for days to come. But what makes some people believers, others non-believers and yet others uncertain. Functional magnetic resonance imaging studies carried out by researchers in the USA could provide new clues about faith.

ADHD delay
Date: Dec 1, 2007
Author: David Bradley
Attention deficit hyperactivity disorder is often in the news, usually regarding its diagnosis and treatment, but little is said about the origins of this behavioural disorder in the maturing brain. Now, MRI has been used to demonstrate that there is a delay in the maturation of certain regions of the brains of ADHD sufferers of about three years.

Axonal damage in the spinal cord of multiple sclerosis patients detected by MRS
Date: Nov 27, 2007
Author:
Axonal damage is a major factor contributing to permanent disability in patients with multiple sclerosis; it has been extensively investigated in the brain using magnetic resonance spectroscopy. In this study, published in Magnetic Resonance in Medicine, MRS was used to investigate the degree of neuronal damage in the cervical spinal cord in MS.
