Researchers found that pallidotomy surgery for Parkinson's disease improves brain activity in areas responsible for controlling movement and decreases abnormal activation in cerebral areas. The study provides new insight into the brain mechanisms responsible for symptomatic improvement following surgery.
Researchers have developed a new imaging technique to visualize brain cells releasing serotonin in humans, potentially resolving the safety debate over two popular diet drugs. The method could provide valuable information on the risks of fenfluramine and dexfenfluramine, and its applications extend beyond diet drug studies.
Researchers found a direct link between changes in the brain's receptor sites and cocaine addiction behavior, suggesting that the body's natural opiates play a key role in craving. The study uses PET scans to measure binding to opiate receptors, providing new potential avenues for predicting relapse and treating addiction.
