A lot of brain development happens early in life, but researchers don\u2019t have a strong understanding of how a baby\u2019s brain develops<\/a> while they\u2019re awake.<\/p>\n

New research from Northeastern University<\/a> sheds light on how babies develop brain network patterns during their first two years of life as they are exposed to new stimuli for the first time using an electroencephalogram, or EEG, which is a test that records the brain\u2019s electrical activity.<\/p>\n

\u201cIt\u2019s such a rapid window of change for the brain to come out into the world,\u201d said Laurel Gabard-Durnam<\/a>, an assistant psychology professor and director of the Plasticity in Neurodevelopment (PINE) Lab at Northeastern University. \u201cIt\u2019s a really exciting window to understand how these things first form and start to work together to coordinate behavior.\u201d<\/p>\n

These patterns, called functional networks, are a set of regions across the brain that are coordinated in their activity in order to achieve some sort of function, said Gabard-Durnam, also a member of Northeastern\u2019s Institute for Cognitive and Brain Health<\/a>.<\/p>\n

\u201cThat\u2019s the best reflection of how the brain does what it does to allow us to behave, move and think,\u201d she added. \u201cIt requires multiple coordinated regions working in sync to get that level of precision and incredible cognitive things done.\u201d<\/p>\n

Researchers have used MRIs on sleeping infants to understand how brain networks are first constructed, but limitations with technology confined how much they were able to understand how brain networks were first constructed or used while infants were awake. But through the use of electroencephalography and other computational tools, scientists found a novel approach to studying the redevelopment of these networks while infants are awake.<\/p>\n

\u201cThe recordings from MRIs were so slow that they cannot effectively capture the movement-to-movement brain activity,\u201d said Priyanka Ghosh, a postdoctoral research fellow at the PINE Lab who worked on the study. \u201cWith EEG, we saw that through infancy, as the baby grows, the network transitions are rapid, getting rapid with age. EEG gives us this flexibility to capture these networks while the baby is awake, which is amazing.\u201d<\/p>\n

Using EEG, researchers were able to see how these babies\u2019 brains organize and build themselves through \u201cmicrostates,\u201d which is a snapshot of brain activity.\u00a0<\/p>\n

The research was the result of what Gabard-Durnam described as \u201ca truly unique international collaboration\u201d through a grant mechanism called Welcome Leap, which allowed researchers to study different cohorts of children around the world to find differences and similarities in their brain development. They collaborated with researchers in Cape Town, South Africa, and Sao Paulo to study babies from those regions over their first two years of life.<\/p>\n

The testing involved showing the subjects, ranging in age from 3 months to 2 years old, baby-friendly images, movies or playing sounds meant to grab their attention. The baby\u2019s brain activity would then show up on a recording machine where scientists, and the parents, could see the brain in action.<\/p>\n

Ghosh said each microstate corresponds to different cognitive networks, with one being more energetically dominant in any given moment.<\/p>\n

\u201cIt\u2019s like switching a TV,\u201d she said. \u201cEach network represents a kind of function. The auditory network corresponds to sensory processing when there is an auditory stimulus. And then there is a very famous default mode network that is the most dominant network in resting state,\u201d she said.<\/p>\n

Despite only lasting milliseconds, these microstates correspond closely with functional networks in adults as the patterns they create repeat over time.<\/p>\n

\u201cYou could think of each one of these as sort of a fingerprint,\u201d Gabard-Durnam said. \u201cIt\u2019s easy to tell when the brain is in this fingerprint state in terms of the activity that\u2019s going on. But which one is energetically dominant in any given moment will change.\u201d<\/p>\n

She added that \u201cthe configuration in that moment is the driving configuration for the brain and then it may switch back. It\u2019s important for understanding what information you\u2019re actually going to take in.\u201d<\/p>\n

The researchers found that as the baby grows, these transitions between networks are more flexible and faster as the myelin sheath increases with age. This fatty lining of nerve cells allows faster transmissions to occur.<\/p>\n

Ghosh said studying babies from two different areas of the world allowed the researchers to also look into how cultural differences might impact development.<\/p>\n

This understanding of early brain development can help with future childhood interventions.<\/p>\n

\u201cThere are a number of very sensitive windows for brain growth, for brain function, for intervention,\u201d Gabard-Durnam said. \u201cWe know that intervention is most helpful and supports are most helpful if we can get to kids early. So there are a lot of reasons for trying to figure out what key brain dynamics are happening in those first one thousand days of life.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"A lot of brain development happens early in life, but researchers don\u2019t have a strong understanding of how…\n","protected":false},"author":2,"featured_media":234468,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[77],"tags":[11766,124661,18,19,17,42622,4226,172,133],"class_list":{"0":"post-234467","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-brain-development","9":"tag-center-for-cognitive-and-brain-health","10":"tag-eire","11":"tag-ie","12":"tag-ireland","13":"tag-neural-networks","14":"tag-psychology","15":"tag-research","16":"tag-science"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/115725278540480242","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/234467","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=234467"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/234467\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/234468"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=234467"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=234467"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=234467"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
