Over 140,000 neurons are joined together by more than 490 feet of wiring, as long as four blue whales placed end to end.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Hundreds of scientists mapped out those connections in stunning detail in a series of papers <a class=\"css-yywogo\" href=\"https:\/\/www.nature.com\/articles\/s41586-024-07558-y\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">published<\/a> on Wednesday in the journal Nature. The wiring diagram will be a boon to researchers who have studied the nervous system of the fly species, Drosophila melanogaster, for generations.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Previously, a tiny worm was the only <a class=\"css-yywogo\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6889226\/\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">adult animal<\/a> to have had its brain entirely reconstructed, with just 385 neurons in its entire nervous system. The new fly map is \u201cthe first time we\u2019ve had a complete map of any complex brain,\u201d said Mala Murthy, a neurobiologist at Princeton who helped lead the effort.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Other researchers said that analyzing the circuitry in the fly brain would reveal principles that apply to other species, including humans, whose brains have 86 billion neurons.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-1\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">In one of the new studies, the researchers tackled the mystery of how sensory signals flow through the brain and prompt it to produce commands. They created a computer simulation of the complete fly brain. When presented with simulated tastes, the artificial brain produced signals to stick out the tongue.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Sebastian Seung, another leader of the project at Princeton, said the simulations reminded him of <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2015\/10\/11\/opinion\/sunday\/will-you-ever-be-able-to-upload-your-brain.html\" title=\"\">long-running speculations<\/a> about how \u201cmind uploading\u201d could allow us to transfer our brains into computers.<\/p>\n<div class=\"css-1336jj\">\n<div class=\"css-121kum4\">\n<div class=\"css-asuuk5\"><noscript><\/p>\n<div class=\"css-7axq9l\" data-testid=\"optimistic-truncator-noscript\"><svg width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" aria-hidden=\"true\" class=\"css-1b5b8u1\"><path fill=\"currentColor\" fill-rule=\"evenodd\" d=\"M2.5 12a9.5 9.5 0 1 1 19 0 9.5 9.5 0 0 1-19 0Zm8.5 1.75v-7.5h2v7.5h-2Zm0 2v2h2v-2h-2Z\" clip-rule=\"evenodd\"\/><\/svg><\/p>\n<div data-testid=\"optimistic-truncator-noscript-message\" class=\"css-6yo1no\">\n<p class=\"css-3kpklk\">We are having trouble retrieving the article content.<\/p>\n<p class=\"css-3kpklk\">Please enable JavaScript in your browser settings.<\/p>\n<\/div>\n<\/div>\n<p><\/noscript><\/p>\n<div class=\"css-1dv1kvn\" id=\"optimistic-truncator-a11y\" tabindex=\"-1\">\n<hr\/>\n<p>Thank you for your patience while we verify access.
