New research suggests doctors conduct a risk-benefit analysis before administering gadolinium, a common contrast agent injected into a patient’s veins before undergoing an MRI scan. Recent studies have shown contrast agent deposits can accumulate in the brain. In some patients, excessive exposure to contrast agents can harm the liver and pancreas. (August 7, 2017)

Your Brain on Autopilot
Ever realized you have driven yourself home but have not really been paying attention? Brain scans have revealed that when your mind wanders, it switches into “autopilot” mode, enabling you to carry on without much conscious thought. Our autopilot mode seems to be run by a set of brain structures called the default mode network (DMN). Several studies have found that the DMN seems to be involved in assessing past events and planning for the future. Others suggest the network is involved in self-awareness.
