Now, researchers have revealed he maintained this ability for months after the stimulation was turned off. This suggests the intervention has caused a rerouting of his neuronal connections through neuroplasticity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe turned everything off completely, for many months, and yet he\u2019s maintained these gains,\u201d says <a href=\"https:\/\/feinstein.northwell.edu\/institutes-researchers\/our-researchers\/chad-bouton\"  rel=\"noreferrer noopener\">Chad Bouton<\/a> at the Feinstein Institutes for Medical Research in New York. \u201cThat\u2019s unheard of.\u201d<\/p>\n\n\n\n\t<div class=\"read-more__standard wp-block-newscientist-read-more\">\n\t\t<a class=\"read-more__standard--wrapper no-animation\" href=\"https:\/\/www.newscientist.com\/article\/2531428-fusogenic-neurosurgery-let-paralysed-pigs-walk-again-are-we-next\/\">\n\t\t\t<strong>Read more<\/strong>\n\t\t\t<p>\u2018Fusogenic\u2019 neurosurgery let paralysed pigs walk again \u2013 are we next?<\/p>\n\t\t<\/a>\n\t<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Keith Thomas, 48, was paralysed from the chest down in July 2020. He had no sensation or control over his limbs and had significant muscle wasting, says Bouton.<\/p>\n<div class=\"advert-wrapper advert__mid-article\">\n\t<div class=\"advert\">\n\t\t<div class=\"advert__inner\">\n\t\t\t\t\t\t\t<p class=\"advert__copy\">\n\t\t\t\t\tAdvertisement\t\t\t\t<\/p>\n\t\t\t\t\t\t<div class=\"advert__slot\" id=\"mid-article-slot\">\n\t\t\t\t<script>\n\t\t\t\t\tif( window?.adverts?.addToArray ) {\n\t\t\t\t\t\twindow.adverts.addToArray( {\n\t\t\t\t\t\t\t\"pos\": \"mid-article-slot\"\n\t\t\t\t\t\t} );\n\t\t\t\t\t}\n\t\t\t\t<\/script>\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n\n\n\n<p class=\"wp-block-paragraph\">In 2023, Bouton and his colleagues performed a double neural bypass surgery on Thomas, placing five electrodes into his brain in regions associated with arm movements and feeling. They then connected computer cables to these electrodes, so artificial intelligence could interpret his movement intentions. That information was then wired into electronic splints that stimulated his arms, hands and fingers to carry out his intended movements, enabling him to pick up coffee cups and scratch his face.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To recreate the sense of feeling, the team embedded force sensors into 3D-printed wearable devices for Thomas\u2019s hands and fingers, which sent feedback via electrical stimulation into the brain\u2019s sensory areas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After conducting a series of experiments \u2013 which even involved <a href=\"https:\/\/www.newscientist.com\/article\/2499936-paralysed-man-can-feel-objects-through-another-persons-hand\/\"  rel=\"noreferrer noopener\">Thomas feeling objects through another person\u2019s hand<\/a> \u2013 Bouton says the team planned to stop the stimulation for about a month, to test for any lingering effects. \u201cThen we had a fire in the building, and it actually forced us to stop stimulation for even longer than we\u2019d planned, for about three months.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\"
