Old brains, new tricks: Rewiring the elderly
Date: Jun 1, 2012
Author: David Bradley
Conventional wisdom has it that after major "rewiring" work during adolescence, the connections between neurones and groups of neurons remain fixed as we get older. However, evidence is emerging from a variety of sources to suggest that even the aged adult brain has plenty of plasticity and can adapt to accommodate novel sensory experiences.

Journal Highlight: Physics of MRI: A primer
Date: May 21, 2012
Author: spectroscopyNOW
A non-mathematical conceptual approach is presented for understanding magnetic resonance image formation from an intuitive perspective. It is based on an introductory lecture given for the past many years during the "MR Physics and Techniques for Clinicians" course at the Annual Meeting of the ISMRM.

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...
