Making an Old Brain Young

ABC News: Making an Old Brain Young: "New ways to manipulate neural plasticity--the brain's ability to rewire itself--could make adult brains as facile as young ones, at least in part. Drugs that target these mechanisms might eventually help treat neurological disorders as diverse as Alzheimer's, stroke, schizophrenia, and autism. But first scientists will need to figure out how to harness this rewiring capacity without damaging vital neural circuitry."
