Hoʻokomo ʻia ka lolo injectable e hoʻopau i ka mea huna o Alzheimer

Ua hana hou nā kānaka ʻepekema ma ke Kulanui ʻo Harvard i kahi mea hana ─ he puʻupuʻu lolo o nā ʻano ─ hiki iā mākou ke hoʻokahi ʻanuʻu kokoke i ka hoʻomaopopo piha ʻana i ka pilina o nā neurons a pehea e unuhi ai kēia mau neurons i nā kaʻina hana kiʻekiʻe e like me ka manaʻo a me ka noʻonoʻo. ʻO ka mea nui, hiki i kēia noiʻi ke paʻa i ke kī i ka wehe hope ʻana i ka mea huna o nā maʻi neurological e like me Alzheimer's a me Parkinson's.  

ʻO ka pepa e pili ana i ka implant, i paʻi ʻia ma Nature Nanotechnology, hōʻike i nā mea paʻakikī o ka implant: kahi ʻāpana palupalu polymer i hoʻopaʻa ʻia me nā ʻāpana uila, i ka wā e hoʻokomo ʻia ai i loko o ka lolo o ka ʻiole, wehe ʻia e like me ka pūnaewele, hoʻopaʻa a hoʻopaʻa iā ia iho i waena o ka. pūnaewele o nā neurons. Ma o kēia injection, hiki ke nānā ʻia ka hana neuronal, ka palapala ʻāina a me ka hoʻopunipuni. He paʻakikī ka hoʻokomo ʻana o ka lolo ma mua me ka maluhia me ka ʻiʻo o ka lolo, akā naʻe, ʻo nā mea palupalu, like me ka siliki o ka polymer mesh ua hoʻomaha ia pilikia.   

I kēia manawa, ua kūleʻa wale kēia ʻenehana i nā ʻiole i hoʻomaʻemaʻe ʻia. ʻOiai ʻoi aku ka maʻalahi o ka nānā ʻana i ka hana o nā neurons i ka wā e ala a neʻe ana nā ʻiole, hāʻawi kēia noiʻi i kahi hoʻomaka maikaʻi e aʻo hou e pili ana i ka lolo. Wahi a Jens Schouenborg (ʻaʻole i komo i ka papahana), he kaukaʻi o Neuroscience ma ke Kulanui ʻo Lund ma Suedena, "He nui ka mana no nā ʻenehana hiki ke aʻo i ka hana o nā helu nui o nā neurons no ka manawa lōʻihi me ka liʻiliʻi wale nō. poino." 

ʻO ka lolo he mea hiki ʻole ke hoʻomaopopo ʻia a paʻakikī. ʻO ka hana i loko o ka lolo nui, nā neural network i hāʻawi i ka pōhaku kihi no ka ulu ʻana o kā mākou ʻano. Ua aie nui kakou i ka lolo; akā naʻe, he nui ka weliweli a mākou i ʻike ʻole ai e pili ana i nā mea kupanaha i loaʻa ma o kēia puʻupuʻu ʻiʻo 3 paona ma waena o ko mākou mau pepeiao.
