With the help of a brain scanner, she spies on what happens inside viewers&#8217; heads when they watch the first episode of the series and then describe the plot. <\/span><\/div>\n<\/li>\n<li>\n<div style=\"text-align: justify;\"><span style=\"font-size: 12pt;\">Powerful technological innovations in human and animal neuroscience in the past decade are enabling researchers to uncover fundamental rules about how individual memories form, organize and interact with each other. <\/span><\/div>\n<\/li>\n<li>\n<div style=\"text-align: justify;\"><span style=\"font-size: 12pt;\">Using techniques for labelling active neurons, for example, teams have located circuits associated with the memory of a painful stimulus in rodents and successfully reactivated those pathways to trigger the memory. <\/span><\/div>\n<\/li>\n<li>\n<div style=\"text-align: justify;\"><span style=\"font-size: 12pt;\">Such findings could one day help to reveal why memories fail in old age or disease, or how false memories creep into eyewitness testimony. These insights might also lead to strategies for improved learning and memory. <\/span><\/div>\n<\/li>\n<li>\n<div style=\"text-align: justify;\"><span style=\"font-size: 12pt;\">Scientists have worked out some basic principles of this broad framework. But testing higher-level theories about how groups of neurons store and retrieve specific bits of information is still challenging. <\/span><\/div>\n<\/li>\n<li>\n<div style=\"text-align: justify;\"><span style=\"font-size: 12pt;\">Researchers now want to explore how specific recollections evolve with time, and how they might be remodelled, distorted or even recreated when they are retrieved.<\/span><\/div>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-size: 12pt;\">For further info on the <a href=\"https:\/\/www.nature.com\/articles\/d41586-018-00107-4\">Nature site<\/a>. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>1. &#8216;Bat-nav&#8217; reveals how the brain tracks other animals By Alison Abbott, published on the Nature News in Jan 12, 2018 The brain&#8217;s navigation system \u2014 which keeps track of where we are in space \u2014 also monitors the movements of others, experiments in bats and rats suggest.
