Over three months, 37 healthy volunteers aged 50-69 had a daily drink containing either a high dose of flavanols -- 900 milligrammes -- or a low dose, 10mg. The scientists carried out brain imaging, measuring blood volume in a key part of the hippocampus called the dentate gyrus, a region of memory formation whose performance typically declines as one ages. The tests entailed a 20-minute pattern-recognition exercise designed to assess a type of memory controlled by the dentate gyrus.</p><br clear="all"/>
