An international team of neuroscientists, anesthesiologists and other medical researchers has learned more about the changes that occur in brain neurotransmitter systems under the influence of psychedelics, anesthetics and cognitive enhancers by studying PET and fMRI scans of brains of people administered such drugs. The study is published in Science Advances.

With as little as 1 percent loss in body weight, a Mediterranean diet appears to slow the signs of accelerated brain aging typical of obesity, according to a new study.
