Working in mice, Bolding and Franks simultaneously recorded spiking activity from neurons in the olfactory bulb and piriform cortex, two important brain regions for olfaction. Odor information was transformed from a representation that was highly concentration dependent in the olfactory bulb to a representation that was largely concentration invariant in the piriform cortex. The underlying mechanism involves a \u201cwinner-takes-all\u201d lateral inhibition. In the collateral network of the piriform cortex, the principal cells responded promptly to output from the olfactory bulb, and recurrent inhibition curtailed the intensity dependence of the signal.<\/p>\n<p>&nbsp;<\/p>\n<p id=\"p-2\"><em>Science<\/em>, this issue p.\u00a0<a href=\"http:\/\/science.sciencemag.org\/lookup\/doi\/10.1126\/science.aat6904\">eaat6904<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; &nbsp; (\uc6d0\ubb38: \uc5ec\uae30\ub97c \ud074\ub9ad\ud558\uc138\uc694~) &nbsp; &nbsp; Science\u00a0\u00a014 Sep 2018: Vol. 361, Issue 6407, pp. 1083-1085 DOI: 10.1126\/science.361.6407.1083-l &nbsp; &nbsp; We still don&#8217;t know how<a href=\"https:\/\/biochemistry.khu.ac.kr\/lab\/?p=1736\" class=\"more-link\">(more&#8230;)<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[33,34,29,30],"tags":[],"class_list":["post-1736","post","type-post","status-publish","format-standard","hentry","category-do-biology","category-lets-do-chemistry","category-lets-do-science","category-recent-science-news"],"aioseo_notices":[],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack-related-posts":[{"id":2245,"url":"https:\/\/biochemistry.khu.ac.kr\/lab\/?p=2245","url_meta":{"origin":1736,"position":0},"title":"Memories reach the cortex rapidly &#038; New dimensions for brain mapping","author":"biochemistry","date":"December 3, 2018","format":false,"excerpt":"\u00a0 \u00a0 How fast do learning-induced anatomical changes occur in the brain?
