implicates the hippocampus in the encoding of early memories,\u201d says developmental and cognitive scientist Vladimir Sloutsky of Ohio State University in Columbus. And that\u2019s important, Sloutsky says, because it shows the hippocampus \u201cis mature enough to encode early memories.\u201d<\/p>\n\n\n\n<p>Young babies can be difficult research subjects. But for the new study, awake babies were kept calm in functional MRI scanners with a parent nearby and earphones to protect them from startling sounds. In the scanner, these babies, who ranged from 4 months old to nearly 25 months old, saw images, one after another, of people, places or objects. All the while, scientists recorded blood flow in the babies\u2019 brains, a proxy of neural activity.<\/p>\n\n\n\n<p>Occasionally, the babies were tested with a pair of images, one of which they had seen before. If the babies looked longer at the previously seen image, researchers reasoned, they likely remembered it. \u201cWe can kind of quantify the strength of their memory based on how much they look at it,\u201d says study coauthor Nick Turk-Browne of Yale University. \u201cAnd then the trick in this sort of study is to then go back and look at, when they first saw the picture, what was different in the brain for pictures that they later had a memory for, versus that they later forgot?\u201d<\/p>\n\n\n\n<p>The difference, it turns out, was in the babies\u2019 hippocampi, seahorse-shaped structures, one on each side of their brains. In the study, 13 babies were younger than a year, and 13 babies were older than a year. The older babies could remember about half of the images they had seen before. And this memory feat corresponded to brain activity in a part of the hippocampus.<\/p>\n\n\n\n<p>The results add to <a href=\"https:\/\/www.sciencenews.org\/blog\/growth-curve\/babies-may-be-good-remembering-and-forgetting\">other evidence<\/a> that babies, the human sort as well as rats and mice, can in fact form memories, and starts to answer how. Added to earlier research, the new study shows \u201cthat in humans, like previously found in rats and mice, infant learning actively engages the hippocampus to form memories,\u201d says neuroscientist Cristina Alberini of New York University.<\/p>\n\n\n\n<p>Still, the results don\u2019t explain why we can\u2019t recall some of the earliest moments of our lives, a phenomenon known as infantile amnesia. It\u2019s possible that these memories aren\u2019t effectively stored elsewhere in the brain. Or it could be that neural traces persist but aren\u2019t able to be called back up. <\/p>\n\n\n\n<p>This second idea is out there, but there\u2019s some evidence for it, Turk-Browne says. Scientists have successfully reactivated infant memories in mice by stimulating the memory trace with light. It\u2019s possible that \u201cthere may be sort of fragments of early memories that are still in your brain, and that with the right kinds of cues, or in the case of animals with stimulation, you could reactivate those memories later in life.\u201d He likens the process to an unsuccessful internet search. \u201cThe search terms your brain is using to access the memory are wrong or different from what they were when you initially stored the memory.\u201d Turk-Browne and his colleagues are now studying how long babies\u2019 memories might last.<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/babies-memories-adult-infantile-amnesia\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>A baby\u2019s early life has a lot of milestones: first giggle, first tooth, first step.
