They compared their results to mathematical models to infer connectivity between different areas of the brain. The study appeared in the Dec. 7 issue of the Journal of Neuroscience.<\/p>\n<p>The subjects had to look for a letter \u201cT\u201d in a box and indicate which way it faced by pressing a button. They were also presented with a \u201cdistractor\u201d: another letter T in a box, but rotated 90 degrees.<\/p>\n<p>The distractor was either similar in appearance to the target, or brightened to be more attention-getting.<\/p>\n<p>Subjects did better in trials with an \u201cattention-getting\u201d distractor than a less obvious one, and lit up specific areas of the brain accordingly.<\/p>\n<p>The new work shows that <strong>the brain doesn\u2019t always \u201cramp up\u201d to deal with the situation at hand<\/strong>, Geng said. Instead,<strong> it changes how traffic moves through the existing hard-wired network &#8212; rather like changing water flow through a network of pipes or information flow over a computer network &#8212; in order to maximize efficiency.<\/strong><\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the UC Davis press release: A new UC Davis study shows how the brain reconfigures its connections to minimize distractions and take best advantage of our knowledge of situations. \u201cIn order to behave efficiently, you want to process relevant sensory information as fast as possible, but relevance is determined by your current situation,\u201d said&hellip;&nbsp;<!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"rop_custom_images_group":[],"rop_custom_messages_group":[],"rop_publish_now":"initial","rop_publish_now_accounts":[],"rop_publish_now_history":[],"rop_publish_now_status":"pending","neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[6],"tags":[42,85,12],"class_list":["post-712","post","type-post","status-publish","format-standard","hentry","category-neuroscience","tag-brain","tag-information","tag-psychology"],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/712","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=712"}],"version-history":[{"count":1,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/712\/revisions"}],"predecessor-version":[{"id":713,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/712\/revisions\/713"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=712"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=712"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=712"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
