Credit: Neuroscience News<\/figcaption><\/figure>\n<p>\u201cWe spend a lot of time wondering, \u2018What is that person feeling, thinking? Did I say something to upset them?\u2019\u201d said senior author\u00a0Rodrigo Braga.<\/p>\n<p>\u201cThe parts of the brain that allow us to do this are in regions of the human brain that have expanded recently in our evolution, and that implies that it\u2019s a recently developed process.<\/p>\n<p>\u201cIn essence, you\u2019re putting yourself in someone else\u2019s mind and making inferences about what that person is thinking when you cannot really know.\u201d<\/p>\n<p>The study found the more recently evolved and advanced parts of the human brain that support social interactions \u2014 called the social cognitive network \u2014 are connected to and in constant communication with an ancient part of the brain called the amygdala.<\/p>\n<p>Often referred to as our \u201clizard brain,\u201d the amygdala typically is associated with detecting threats and processing fear. A classic example of the amygdala in action is someone\u2019s physiological and emotional response to seeing a snake:\u00a0startled body, racing heart, sweaty palms. But the amygdala also does other things, Braga said.<\/p>\n<p>\u201cFor instance, the amygdala is responsible for social behaviors like parenting, mating, aggression and the navigation of social-dominance hierarchies,\u201d said Braga, an assistant professor of neurology at Northwestern University Feinberg School of Medicine.<\/p>\n<p>\u201cPrevious studies have found co-activation of the amygdala and social cognitive network, but our study is novel because it shows the communication is always happening.\u201d<\/p>\n<p>The study\u00a0was published Nov. 22\u00a0in the journal\u00a0<em>Science Advances<\/em>.<\/p>\n<p><strong>High-resolution brain scans were key<\/strong><\/p>\n<p>Within the amygdala, there\u2019s a specific part called the medial nucleus that is very important for social behaviors. This study was the first to show the amygdala\u2019s medial nucleus is connected to newly evolved social cognitive network regions, which are involved in thinking about other people.<\/p>\n<p>This link to the amygdala helps shape the function of the social cognitive network by giving it access to the amygdala\u2019s role in processing emotionally important content.<\/p>\n<p>This was only possible because of functional magnetic resonance imaging (fMRI), a noninvasive brain-imaging technique that measures brain activity by detecting changes in blood oxygen levels.<\/p>\n<p>A collaborator at the University of Minnesota and co-author on the study, Kendrick Kay, provided Braga and co-corresponding author\u00a0Donnisa Edmonds\u00a0with fMRI data from six study participants\u2019 brains, as part of the Natural Scenes Dataset (NSD).<\/p>\n<p>These high-resolution scans enabled the scientists to see details of the social cognitive network that had never been detected on lower-resolution brain scans. What\u2019s more, they were able to replicate the findings up to two times in each individual.<\/p>\n<p>\u201cOne of the most exciting things is we were able to identify network regions we weren\u2019t able to see before,\u201d said Edmonds, a neuroscience Ph.D. candidate in Braga\u2019s lab at Northwestern.<\/p>\n<p>\u201cThat\u2019s something that had been underappreciated before our study, and we were able to get at that because we had such high-resolution data.\u201d<\/p>\n<p><strong>Potential treatment of anxiety, depression<\/strong><\/p>\n<p>Both anxiety and depression involve amygdala hyperactivity, which can contribute to excessive emotional responses and impaired emotional regulation, Edmonds said.<\/p>\n<p>Currently, someone with either condition could receive deep brain stimulation for treatment, but since the amygdala is located deep within the brain, directly behind the eyes, it means having an invasive, surgical procedure.<\/p>\n<p>Now, with this study\u2019s findings, a much less-invasive procedure, transcranial magnetic stimulation (TMS), might be able to use knowledge about this brain connection to improve treatment, the authors said.<\/p>\n<p>\u201cThrough this knowledge that the amygdala is connected to other brain regions \u2014 potentially some that are closer to the skull, which is an easier region to target \u2014 that means people who do TMS could target the amygdala instead by targeting these other regions,\u201d Edmonds said.<\/p>\n<h2 class=\"wp-block-heading\">About this neuroscience, emotion, and social skills research news<\/h2>\n<p class=\"has-background\" style=\"background-color:#ffffe8\"><strong>Author:<\/strong><a href=\"http:\/\/neurosciencenews.com\/cdn-cgi\/l\/email-protection#dcb7afbdb1a9b9b0afb3b29cb2b3aea8b4abb9afa8b9aeb2f2b9b8a9\" target=\"_blank\" rel=\"noreferrer noopener\"><strong> <\/strong>Kristin Samuelson<\/a><br \/><strong>Source: <\/strong><a href=\"https:\/\/northwestern.edu\" target=\"_blank\" rel=\"noreferrer noopener\">Northwestern University<\/a><br \/><strong>Contact: <\/strong>Kristin Samuelson \u2013 Northwestern University<br \/><strong>Image: <\/strong>The image is credited to Neuroscience News<\/p>\n<p class=\"has-background\" style=\"background-color:#ffffe8\"><strong>Original Research: <\/strong>Open access.<br \/>\u201c<a href=\"https:\/\/doi.org\/10.1126\/sciadv.adp0453\" target=\"_blank\" rel=\"noreferrer noopener\">The human social cognitive network contains multiple regions within the amygdala<\/a>\u201d by Rodrigo Braga et al. <em>Science Advances<\/em><\/p>\n<hr class=\"wp-block-separator has-text-color has-pale-cyan-blue-color has-alpha-channel-opacity has-pale-cyan-blue-background-color has-background\"\/>\n<p><strong>Abstract<\/strong><\/p>\n<p><strong>The human social cognitive network contains multiple regions within the amygdala<\/strong><\/p>\n<p>Reasoning about someone\u2019s thoughts and intentions\u2014i.e., forming a \u201ctheory of mind\u201d\u2014is a core aspect of social cognition and relies on association areas of the brain that have expanded disproportionately in the human lineage.<\/p>\n<p>We recently showed that these association zones comprise parallel distributed networks that, despite occupying adjacent and interdigitated regions, serve dissociable functions. One network is selectively recruited by social cognitive processes. What circuit properties differentiate these parallel networks?<\/p>\n<p>Here, we show that social cognitive association areas are intrinsically and selectively connected to anterior regions of the medial temporal lobe that are implicated in emotional learning and social behaviors, including the amygdala at or near the basolateral complex and medial nucleus.<\/p>\n<p>The results suggest that social cognitive functions emerge through coordinated activity between internal circuits of the amygdala and a broader distributed association network, and indicate the medial nucleus may play an important role in social cognition in humans.<\/p>\n<p> <!-- Form created by Optin Forms plugin by WPKube: create beautiful optin forms with ease! --> <!-- https:\/\/wpkube.com\/ --><!--optinforms-form5-container--> <!-- \/ Optin Forms --> <\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/neurosciencenews.com\/amygdala-emotion-social-neuroscience-28120\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summary: A new study uncovers constant communication between the human brain\u2019s social cognitive network, responsible for understanding others\u2019 thoughts, and the amygdala, known for processing fear and emotions.
