The emulation covers over 125,000 neurons and 50 million synapses.<\/p>\n<p>According to co-founder Alex Wissner-Gross, the startup mapped the fruit fly&#8217;s neural wiring from electron microscopy data and connected it to a virtual fly body running in <a href=\"https:\/\/the-decoder.com\/minds-eye-how-physics-data-improves-large-language-models\/\" rel=\"nofollow noopener\" target=\"_blank\">MuJoCo<\/a>, a physics simulation engine.<\/p>\n<p>Previous projects like OpenWorm worked with far smaller nervous systems, just 302 neurons, or relied on machine learning techniques like reinforcement learning instead of actual brain data. Eon takes a fundamentally different approach. Rather than building AI, the startup wants to digitally copy and simulate real brains, neuron by neuron. The fruit fly is just the starting point. Within two years, Eon plans to emulate a mouse brain with 70 million neurons. The long-term goal is simulating a human brain.<\/p>\n<p>Eon published the code for its brain model on <a target=\"_blank\" rel=\"noopener nofollow\" href=\"http:\/\/eonsystemspbc\/fly-brain\">GitHub<\/a>, though it&#8217;s based on a paper by Philip Shiu et al. that already appeared in Nature in 2024. The actually novel part, connecting the brain emulation to a simulated body, hasn&#8217;t been released yet.<\/p>\n<p>\t\t\t\tAI News Without the Hype \u2013 Curated by Humans<\/p>\n<p>\n\t\t\t\t\tAs a THE DECODER subscriber, you get ad-free reading, our weekly AI newsletter, the exclusive &#8220;AI Radar&#8221; Frontier Report 6\u00d7 per year, access to comments, and our complete archive.\t\t\t\t<\/p>\n<p>\t\t\t\t<a href=\"https:\/\/the-decoder.com\/subscription\/\" class=\"inline-block text-white bg-(--heise-primary) mt-3 hover:bg-blue-800 focus:ring-4 focus:outline-none focus:ring-blue-300 font-medium rounded-sm w-full sm:w-auto  pl-3 pr-3 py-2.5 text-center newsletter-submit-button hover:no-underline\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n\t\t\t\t\tSubscribe now\t\t\t\t<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Eon Systems says it has connected a complete fruit fly brain emulation to a virtual body, producing multiple&hellip;\n","protected":false},"author":2,"featured_media":331841,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[164,163551,85,46,23628,141],"class_list":["post-331840","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-brain","tag-eon-systems","tag-il","tag-israel","tag-neuromorphic-computing","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/331840","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=331840"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/331840\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/331841"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=331840"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=331840"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=331840"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
