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.

Rapid eye scan in multiple sclerosis
Date: Nov 1, 2007
Author: David Bradley
MRI brain scans have been used to calibrate and corroborate the results of a new eye-scanning technique that can diagnose multiple sclerosis in a few minutes. The technique, optical coherence tomography (OCT), scans the layers of nerve fibres in the retina to reveal nerve damage associated with the disease. The quick test will ultimately complement more detailed MRI studies of the brain should nerve damage be found.

Cerebral sounds
Date: Oct 1, 2007
Author: David Bradley
Researchers have used functional MRI to locate the part of the brain responsible for constructing the "sound space" that allows us to locate the position of a particular noise. The results confirm the findings of an earlier controversial study of the planum temporale.

Current status of functional MRI on small animals: application to physiology, pathophysiology, and cognition
Date: Aug 16, 2007
Author:
This review aims to make the reader aware of the potential of functional MRI in brain activation studies in small animal models. As small animals generally require anaesthesia for immobilization during MRI protocols, this is believed to be a serious limitation to the type of question that can be addressed with fMRI.
