Assessment of metabolic changes in the striatum of a rat model of parkinsonism: an in vivo 1H MRS study
Date: Feb 24, 2009
Author:
Degeneration of the dopaminergic neurons of the substantia nigra pars compacta in Parkinson's disease induces an abnormal activation of the glutamatergic neurotransmission system within the basal ganglia network and related structures. The aim of this study was to use proton MRS to show metabolic changes in the striatum of 6-hydroxydopamine-lesioned rats, a rodent animal model of Parkinson's disease.

Crime and punishment
Date: Jan 1, 2009
Author: David Bradley
A truly interdisciplinary collaboration between biology, law and neuroscience at Vanderbilt University has used functional magnetic resonance imaging fMRI to watch how the brain changes when a person thinks about crime and punishment.

Monitoring response to chemotherapy of non-Hodgkin's lymphoma xenografts by T2-weighted and diffusion-weighted MRI
Date: Dec 18, 2008
Author:
An effective method for in vivo detection of early therapeutic response of patients with non-Hodgkin's lymphoma would enable personalized clinical management of cancer therapy and facilitate the design of optimal treatment regimens. This study evaluates the feasibility of T2-weighted MRI and diffusion-weighted MRI for in vivo detection of response of human diffuse large B-cell lymphoma xenografts in severe combined immunodeficient mice to chemotherapy.

Minestrone and magnetic resonance
Date: Dec 1, 2008
Author: David Bradley
Researchers in the US and France may have overturned decades of theory in magnetic resonance studies by spotting a discrepancy in the way nuclear spins behave. Their new mathematical model of the process improves our understanding of atomic behaviour and could lead to better NMR spectra, sharper magnetic resonance images, and perhaps one day a fully portable MRI machine.

Voting and image
Date: Nov 1, 2008
Author: David Bradley
Functional magnetic resonance imaging studies reveal that voters are persuaded more by the negative aspects of a politician's looks than by the positive features. The findings apply specifically if the voter was previously unaware of the politician. Ahead of the US elections, voters there should read on but let their political conscience guide their voting decision.

Prognostic MRI biomarkers of treatment efficacy for retinopathy
Date: Oct 22, 2008
Author:
There is a pressing need for retina-specific imaging biomarkers that robustly measure early changes in physiology, are linked to the histopathology responsible for vision loss, and, importantly, predict treatment efficacy. In this paper, the authors conclude that functional MRI biomarkers are most promising for prognostic evaluation of treatment efficacy earlier in the course of retinopathy than is currently possible.

Anticipating excitation
Date: Oct 1, 2008
Author: David Bradley
Functional magnetic resonance imaging (fMRI) has revealed a reason why the excitement of unwrapping presents dwindles as our brains get older and more jaded. According to a new study, a biochemical pathway is responsible for mellowing our expectations.
