Brain reboot: Anaesthetic awakening
Date: May 1, 2012
Author: David Bradley
A new imaging study has demonstrated how the lower, more primitive part of the brain seem to pull consciousness up by its bootstraps, almost as a computer "boots" before the graphical user interface that is full self-awareness produced by the higher parts of the brain are initiated.

Journal Highlight: Iron deposition in pain-regulatory nuclei in episodic migraine and chronic daily headache by MRI
Date: Apr 23, 2012
Author: spectroscopyNOW
Magnetic resonance imaging findings of iron accumulation in the brain, especially in periaqueductal gray and red nucleus, have been correlated with both duration of illness and frequency of attacks.

MRI reads early signs: Dyslexia diagnosis
Date: Feb 1, 2012
Author: David Bradley
Children at risk of dyslexia show differences in brain activity on magnetic resonance imaging scans even before they start to learn to read, a study at the Children's Hospital Boston has found.

Journal Highlight: The differences in neural network activity between methamphetamine abusers and healthy subjects performing an emotion-matching task: functional MRI study
Date: Jan 11, 2012
Author:
Methamphetamine (MA) abusers commonly exhibit socially problematic behaviors, such as diminished empathy, decreased emotional regulation and interpersonal violence, which may be attributable to alterations in emotional experience. However, few studies have used functional MRI to examine directly the emotional experience of threatening or fearful non-face images in MA abusers. This study investigates possible differences in neural correlates of negative emotional experiences between abstinent MA abusers and...

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.
