A silent spot: MRI reveals memory deficit
Date: Jan 5, 2012
Author: David Bradley
A new magnetic resonance study has linked so-called silent strokes that lead to small patches of dead brain cells with memory loss in elderly adults. The problem is thought to afflict one in four older adults with an important memory deficit.

Doctors who don't pay attention: Success chasers
Date: Dec 1, 2011
Author: David Bradley
Functional magnetic resonance imaging (fMRI) has been used to look at the brain activity of 35 experienced physicians from various non-surgical disciplines as they make decisions. The study shows that those physicians seen to pay most attention to failures as well as successes become more adept at deciding on the correct treatment.

Not so young at heart: MRI reveals plaques
Date: Nov 1, 2011
Author: David Bradley
Atherosclerosis - the potentially lethal accumulation of fatty deposits in the walls of one's arteries - is commonly thought of as a disorder associated with old age. However, an MRI study by the Heart and Stroke Foundation that measured fat distribution more precisely than before reveals that young people are also susceptible to the disorder.

Your dreams: Coming soon to YouTube?
Date: Oct 1, 2011
Author: David Bradley
Computational models of functional Magnetic Resonance Imaging has allowed researchers to reconstruct moving images from the blood flow in the visual cortex of volunteers as they watch a video clip. Fancifully, the technique might one day allow one to "record" one's dreams or to visualise what a patient in a chronic vegetative state or coma might be seeing and so perhaps open up a way to communicate with such patients.

Sweet, sweet: Memorable image
Date: Sep 1, 2011
Author: David Bradley
A new functional magnetic resonance imaging (fMRI) study in the US shows that our memories seem to work more effectively when our brains are prepared to absorb new information.

Pay up and eat up: The true cost of food
Date: Aug 1, 2011
Author: David Bradley
Ghrelin, a naturally occurring gut hormone, increases our willingness to pay for food, while simultaneously decreasing our willingness to pay for non-food items, according to researchers who have tracked behaviour linked to the hormone with functional MRI.

Offensive scans: Impulsiveness and delinquency
Date: Jul 1, 2011
Author: David Bradley
Youthful character traits, such as impulsiveness, are often considered amusing until they lead to juvenile delinquency and youth criminality. Now, functional magnetic resonance imaging (fMRI) of the brains of young offenders, of both impulsive and non-impulsive character hints at activity in a particular brain structure as being associated more commonly with the negative aspects of this personality trait.

Aerobics and the elderly: fMRI reveals benefits of staying active
Date: Jun 1, 2011
Author: David Bradley
Increased physical activity involving aerobic exercise might slow age-related decline according to a new functional magnetic resonance imaging and transcranial magnetic stimulation study. The study shows how the brain's motor cortex changes as we get older particularly in those people who become more sedentary as they do so. However, maintaining a physically active lifestyle can preclude the changes that lead to unnecessary decline.

Zen and the art of decision making: fMRI revelations
Date: May 1, 2011
Author: David Bradley
Buddhists are different from other people, at least when they meditate on an important decision. Functional magnetic resonance imaging (fMRI) shows that specific regions of the meditating brain become active when confronted with an ethical decision but that these are different from the brain regions apparently active in people of a less Zen disposition attempting to make the same decision.

Weighing up breast risk: MRI evidence and diabetes link
Date: Apr 1, 2011
Author: David Bradley
A magnetic resonance imaging study reduces the weight of earlier experiments that correlate a high breast volume with visceral adipose tissue (VAT) and a risk of type 2 diabetes.
