Izimila zobuchopho ezijovayo ukuxazulula imfihlakalo ye-Alzheimer's

Ososayensi base-Harvard University basanda kusungula idivayisi ─ i-brain chip yezinhlobo  ─  engasithatha isinyathelo esisodwa eduze ukuze siqonde ngokugcwele ukusebenzisana kwama-neurons kanye nendlela lama-neurons ahumusheka ngayo ezinqubweni eziphakeme, zokuqonda ezifana nomzwelo nomcabango. Okuphawuleka kakhulu, lolu cwaningo lungase lubambe ukhiye ekugcineni uvule imfihlo yezifo zemizwa njenge-Alzheimer's kanye ne-Parkinson.  

Iphepha eliku-implant, elishicilelwe ku-Nature Nanotechnology, lichaza ubunkimbinkimbi bokufakelwa: i-soft, i-polymer mesh egcwele izingxenye ze-electronic, okuthi, lapho ijova ebuchosheni begundane, ivuleke njengewebhu, ixhume futhi izibambe phakathi inethiwekhi yama-neurons. Ngalo mjovo, umsebenzi we-neuronal ungalandelelwa, ufakwe imephu futhi usetshenziswe. Ukufakelwa kobuchopho kwangaphambilini kube nobunzima bokuhlangana ngokuthula nezicubu zobuchopho, kodwa izici ezithambile, ezifana nosilika ze-polymer mesh ziye zayimisa leyo nkinga.   

Kuze kube manje, le ndlela iphumelele kuphela kumagundane alaliswa izinzwa. Noma ukulandelela umsebenzi wama-neurons kuba nzima kakhulu uma amagundane ephapheme futhi ehamba, lolu cwaningo lunikeza isiqalo esithembisayo sokufunda kabanzi mayelana nobuchopho. Ngokuka-Jens Schouenborg (owayengabandakanyeki kulo msebenzi), uprofesa we-Neuroscience e-Lund University e-Sweden, “Kunamandla amakhulu amasu angakwazi ukufunda ukusebenza kwezinombolo ezinkulu zama-neurons isikhathi eside ngokuncane kuphela. umonakalo." 

Ubuchopho yisitho esingaqondakali, esiyinkimbinkimbi. Umsebenzi ongaphakathi kwamanethiwekhi obuchopho amakhulu, we-neural unikeze isisekelo sokuthuthukiswa kwezinhlobo zethu zezilwane. Sikweleta okuningi ebuchosheni; kodwa-ke, kusekuningi okubi kakhulu esingakwazi ngempela mayelana nezimangaliso ezizuzwe ngalesi sigaxa senyama esingamakhilogremu angu-3 phakathi kwezindlebe zethu.
