They will each receive an equal share of a prize of 12m Swedish kronor (about \u00a3900,000).<\/p>\n<p class=\"dcr-1s160rg\">The 2026 award is the 117th time the prize has been given. Of the 235 laureates \u2013 including the latest winners \u2013 only 14 have been women and none have been awarded to black scientists.<\/p>\n<p class=\"dcr-1s160rg\">In a nutshell the trio\u2019s research led to the development of a light-sensitive switch that can be used to control nerve cells in the living brain, switching them on or off.<\/p>\n<p class=\"dcr-1s160rg\">The discovery had its origins in research by Hegemann, who wanted to explore how a green alga called Chlamydomonas swam towards light. \u201cHe discovered that its eye spot contains a light-sensitive protein that converts light almost instantly into an electrical signal, allowing the alga to move,\u201d said Abdel El Manira, a professor of neuroscience at the Karolinska Institute and member of the Nobel assembly.<\/p>\n<p class=\"dcr-1s160rg\">Nagel and Hegemann identified the proteins, called channelrhodopsins, and working with frog egg cells they revealed that when the proteins were exposed to blue light, they allowed charged particles \u2013 or ions \u2013 to flow into the cell, producing an electrical impulse.<\/p>\n<p class=\"dcr-1s160rg\">Further work by the pair revealed that when the genetic instructions for one of the proteins were inserted into human or mouse kidney cells, those cells became light sensitive.<\/p>\n<p class=\"dcr-1s160rg\">Deisseroth took the discovery even further, using rats to demonstrate that by introducing the gene for a channelrhodopsin into nerve cells, it was possible to produce electrical signals in them using light.<\/p>\n<p>Karl Deisseroth at work in his laboratory at Stanford University school of medicine in Palo Alto, California.

I hope this helps to boost all efforts on optogenetic vision restoration to bring back vision to blind patients,\u201d he said.<\/p>\n<p class=\"dcr-1s160rg\">Anna Wedell, a professor at Karolinska Institute and a member of the Nobel committee for physiology or medicine, said the laureates\u2019 work had provided new possibilities to map which cells were responsible for which functions, and which cells communicated with each other, opening up a new understanding of the function of the brain.<\/p>\n<p class=\"dcr-1s160rg\">\u201cThe brain is our most complex organ and we have very little understanding of how it works and we have had very few methods to proceed in that understanding,\u201d she said.<\/p>\n<p class=\"dcr-1s160rg\">\u201cWe\u2019ve had anatomical maps and correlations, but now we have a tool that can provide cause-and-effect relationships so we can get a functional map of the brain, exactly pinpoint which cells do what, which cells are responsible for creating behaviours or even emotions and memories in the brain.\u201d<\/p>\n<p class=\"dcr-1s160rg\">Wedell said that by studying animals to understand how a normal, healthy brain worked, it was then possible to explore what happens when thing went wrong \u2013 for example in the case of diseases such as dementia, epilepsy and addiction.<\/p>\n<p class=\"dcr-1s160rg\">\u201cBy understanding which cells are active in these diseases in the mouse, we can also understand where to look in the human,\u201d she said.<\/p>\n","protected":false},"excerpt":{"rendered":"The Nobel prize in physiology or medicine 2026 has been awarded to three scientists for their work investigating&hellip;\n","protected":false},"author":2,"featured_media":792783,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[49,50,51,47,52,48],"class_list":["post-792782","post","type-post","status-publish","format-standard","has-post-thumbnail","category-headlines","tag-headlines","tag-news","tag-top-news","tag-top-stories","tag-topnews","tag-topstories"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/792782","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=792782"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/792782\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/792783"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=792782"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=792782"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=792782"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
