Study reveals how the brain volume changes in Parkinson's patients

Researchers of the Human Brain Project (HBP) found that in Parkinson’s disease the volumes of certain brain regions decrease over time in a specific pattern that is associated with clinical symptoms and largely coincides with the pattern described in Braak’s famous staging theory.

Discovery could lead to new treatments to minimize cravings in people with addictions

For some people with alcohol use disorder, it might be the sight of a familiar bar or a favorite bottle; for others, it might be the feeling of leaving the office after a stressful day at work or stepping into a crowded party. Most people who struggle with drug or alcohol addiction have particular cues that set off their cravings.

Study finds brain circuit controlling drug withdrawal-induced anxiety and reinstatement

New research from the University of California, Irvine, finds that drug withdrawal-induced anxiety and reinstatement of drug seeking behaviors are controlled by a single pathway in the brain and centered around dopamine cells.
