Enriched environments help fight off Alzheimer’s
More proof that “use it or lose it” applies to the aging brain. A new study published in the March 6, 2013 issue of “Neuron” found that “prolonged exposure to an enriched environment” activated receptors in the brain, which in turn triggered a signaling pathway that kept amyloid beta protein (the stuff that forms senile plaques) from weakening communication between cells in the hippocampus. (The hippocampus deals with short- and long-term memory.)
