Spontaneous Brain Fluctuations Influence Risk-taking

Minute-to-minute fluctuations in human brain activity, associated with changing levels of dopamine, impact whether we make risky decisions, a new University College London study has found. The findings could help explain why humans are inconsistent and sometimes irrational. “Experts have long struggled to explain why people are so erratic, making one decision one day and […]

Antioxidant Precursor Molecule Could Improve Parkinson’s

N-acetylcysteine (NAC) is a naturally occurring molecule that replenishes one of the body’s antioxidants and now shows potential benefit as part of a standard course of treatment for patients with Parkinson’s disease, according to a new study. The study found improvements in dopamine levels, the primary neurotransmitter that is specifically decreased in Parkinson’s disease, as […]

Procrastination: Genetic, Anatomical And Functional Differences Sway Separately

In women, the tendency toward procrastination is associated with a genetic predisposition towards a higher level of dopamine in the brain. Researchers from Ruhr-Universität Bochum and the Technical University of Dresden discovered this using genetic analyses and questionnaires. They were unable to identify this correlation in men. “The neurotransmitter dopamine has repeatedly been associated with […]

Cerebellum Found To Activate The Ventral Tegmental Area

The brain’s cerebellum, long believed to be mainly involved in coordinating movement, helps control the brain’s reward circuitry, researchers at Albert Einstein College of Medicine report. The finding suggests that the cerebellum plays a major role in reward processing and social behaviors and could potentially lead to new strategies for treating addiction. “The notion that […]
