Electrostimulation may improve short-term memory and thinking skills

In a recently published study in Nature Neuroscience, researchers have demonstrated that a non-invasive brain stimulation procedure could improve memory and thinking in older adults. The researchers state that this electrostimulation could improve the working memory of people in their 70s so that their performance on memory tasks is indistinguishable from that of 20-year-olds. Within the study, the researchers asked a group of individuals in their 20s and a group of individuals in their 60s and 70s to performs a series of memory tasks. For example, the study participants were asked to view an image and then after a brief...
