Dopamine leaves its mark in brain scans
Researchers use functional magnetic resonance imaging (fMRI) to identify which areas of the brain are active during specific tasks. The method reveals areas of the brain, in which energy use and hence oxygen content of the ...

Scientists identify metabolic link between aging, Parkinson's
(Medical Xpress)—University of Alabama researchers identified within animal models an enzyme that links genetic pathways that control aging with the death of dopamine neurons – a clinical hallmark of Parkinson's disease.

Turning off depression in the brain
Scientists have traced vulnerability to depression-like behaviors in mice to out-of-balance electrical activity inside neurons of the brain's reward circuit and experimentally reversed it – but there's a twist.

Two dimensions of value: Dopamine neurons represent reward but not aversiveness
To make decisions, we need to estimate the value of sensory stimuli and motor actions, their "goodness" and "badness." We can imagine that good and bad are two ends of a single continuum, or dimension, of value. This would ...

Genetic manipulation of urate alters neurodegeneration in mouse model of Parkinson's disease
A study by Massachusetts General Hospital researchers adds further support to the possibility that increasing levels of the antioxidant urate may protect against Parkinson's disease. In their report published in PNAS Early ...

Scientists identify neurotranmitters that lead to forgetting
While we often think of memory as a way of preserving the essential idea of who we are, little thought is given to the importance of forgetting to our wellbeing, whether what we forget belongs in the "horrible memories department" ...
