Kuyini Ukudlidliza Okungu-40 Hz? Ucwaningo lwe-MIT Olushintsha Isayensi Ye-Alzheimer's

Ukudlidliza komzimba wonke okungu-40 Hz kungenza ubuchopho busebenze ukuze kususwe amaprotheni ahlobene ne-Alzheimer's. Lokhu akuyona inkolelo-mbono - kungumphumela weshumi leminyaka locwaningo lwe-MIT, oluqinisekiswe ngokuzimela ngamalebhu emazweni amaningi. Uma ufuna ukuqonda isayensi ngemuva kokwelashwa kokudlidliza, qala lapha.

Kungani Lolu Cwaningo Lufanelwe Ukuthathwa Ngokungathi Kakhulu

Ukwelashwa ngokudlidliza kulula ukukulahla. Imboni yezempilo ichithe iminyaka ihlanganisa izimangalo zezempilo ezingacacile kumadivayisi angenzi lutho kakhulu. Ngakho-ke uma isayensi iqinile, ivame ukungcwatshwa ngaphansi komsindo.

Lokhu kuhlukile. Ucwaningo mayelana nokuvuselelwa kwe-40 Hz luqale e-MIT's Picower Institute for Learning and Memory - esinye sezikhungo ze-neuroscience ezicashunwe kakhulu emhlabeni. Lwaqala ngephepha lika-2016 ku- Nature , elinye lamaphephandaba esayensi akhetheke kakhulu akhona. Kusukela ngaleso sikhathi, luye lwaphindwa futhi lwandiswa amaqembu azimele eHarvard Medical School, amanyuvesi eScotland, kanye nezikhungo zocwaningo eShayina.

NgoMashi 2025, ilebhu kaTsai yashicilela isibuyekezo esibanzi ku- PLOS Biology esifingqa iminyaka eyishumi yemiphumela ezifundweni eziningi. Isiphetho sasingenaso isixwayiso noma sivikelwe: ubufakazi bokukhuthazwa kwe-gamma engu-40 Hz kanye nempilo yobuchopho bungokoqobo, bukhula, futhi buhlala bunjalo kuwo wonke amalebhu.

Lolu akulona ucwaningo olulodwa oluthembisayo. Kuyiminyaka eyishumi yobufakazi obuhambisanayo obuvela ezikhungweni ezizimele. Lokho kuhlukanisa kubalulekile.

Kuyini i-40 Hz, nokuthi kwenzekani ebuchosheni

Ubuchopho bakho bukhiqiza imijikelezo kagesi ngezikhathi ezahlukene kuye ngokuthi benzani. Ngesikhathi sokulala okujulile, amaza ahamba kancane. Ngesikhathi sokuqwashisa okukhululekile, asheshayo. Ngemijikelezo engu-40 ngomzuzwana — 40 Hz — ubuchopho bukhiqiza lokho ososayensi bezinzwa abakubiza ngokuthi amaza e-gamma. Lokhu kuhlotshaniswa nokunaka okugxilile, inkumbulo yokusebenza, kanye nokuxhumana phakathi kwezifunda ezahlukene zobuchopho ezisekela ukucabanga okucacile.

Kubantu abanesifo i-Alzheimer's, umsebenzi we-gamma uncishiswa ngokulinganiswa. Ubuchopho bulahlekelwa isigqi sawo. Sekuyiminyaka eminingi, lokhu kwakucatshangwa ukuthi kuyisibonakaliso sokuwohloka kwemizwa - into eyenzekayo njengoba lesi sifo siqhubeka. I-MIT ibuze umbuzo ohlukile: kuthiwani uma futhi kuyingxenye yalokho okuqhubekisela phambili lesi sifo? Futhi uma kunjalo, ingabe ukubuyisela leso sigqi kungenza ukuzivikela kobuchopho kusebenze?

Impendulo yaphenduka yebo. Ubuchopho bunesistimu yalo yokukhipha udoti — uhlobo lwenethiwekhi yokukhipha amanzi yangaphakathi ekhipha amaprotheni anobuthi ngesikhathi sokuphumula nokuvuselela. Abacwaningi be-MIT bathole ukuthi ukuvuselela okungu-40 Hz kuvuselela lolu hlelo. Luvula inqubo yokuhlanza yobuchopho, okwandisa ukususwa kwamaprotheni e-amyloid ne-tau aqongelela esifweni i-Alzheimer's.

Kusho Ukuthi Lokhu Kusho Ukuthi — Kunoma Ubani Ocabanga Ngempilo Yobuchopho

Ukubaluleka kwalolu cwaningo akugcini kubantu abane-Alzheimer's. Izindlela ezitholwe yilolu cwaningo — uhlelo lokususa udoti ebuchosheni, ukulondolozwa kokuxhumana kwezinzwa, nokunciphisa ukwakheka kwamaprotheni — zibalulekile empilweni yobuchopho kuyo yonke impilo.

Uma unesithakazelo mathupha ekuvikeleni ukusebenza kwengqondo njengoba ukhula, lena ingenye yezindlela ezingezona ezemithi ezibhalwe kahle kakhulu ezingaphansi kocwaningo olunzulu lwesayensi okwamanje. Ayibandakanyi izidakamizwa, ayidingi ukubhekwa kwezokwelapha ukuze kusetshenziswe ngendlela enempilo, futhi indlela esebenza ngayo iyaqondakala kakhulu.

Uma usekela ilungu lomndeni elidala, noma usebenza endaweni lapho ukwehla kwengqondo kuyindaba ekhathazayo, ucwaningo lunikeza okuthile okuqondile: imvamisa ethile, indlela ethile, kanye nobufakazi obuhambisana nayo - hhayi isimangalo sempilo esingaqondakali.

Ucwaningo lwango-2023 lwabantu abangaphezu kwe-100 eScotland lubonise ukukhunjulwa kwenkumbulo okuthuthukisiwe kusetshenziswa ukukhuthazwa kwe-gamma-frequency. Ithimba laseHarvard libonise ukwehla kwe-tau okulinganiselwe kubantu abazithandelayo. Lokhu akuzona izifundo zezilwane. Ukuhunyushwa kwabantu kuyaqhubeka, futhi imiphumela yokuqala iyahambisana nalokho okwabikezelwa amamodeli ezilwane.

Akuwona Wonke Amadivayisi Okudlidliza Angenza Lokhu

Yilapho isayensi inemiphumela eqondile engokoqobo.

Ucwaningo lusebenzise imishini ekwazi ukuletha isignali ezinzile neqondile engu-40 Hz. Lokho kucaca akuyona into eyenzeka ngengozi — yiphuzu eliphelele. Ubuchopho bungena esigqini esisitholayo. Uma imvamisa ingacacile, ingazinzile, noma imane ingalungile, umphumela awuveli.

Amapulatifomu amaningi okudlidliza kwabathengi asebenzisa ama-motor kagesi ukuze akhiqize ukudlidliza. Imvamisa abayikhiqizayo inqunywa ukwakheka ngokomzimba kwe-motor — ayinakulawulwa ngokunembile, futhi ayikwazi ukukhiywa ngokuthembekile ku-40 Hz. Lokho okuzwayo epuletini lokudlidliza elijwayelekile ukunyakaza komshini, hhayi imvamisa elungisiwe.

Ubuchwepheshe bokudlidliza kwe-Sonic busebenza ngendlela ehlukile. Busebenzisa ama-transducer omsindo — isimiso esifanayo nesipikha — ukuguqula isignali kagesi ibe ukudlidliza komshini. Ngenxa yokuthi imvamisa ichazwa isignali kagesi, ingasethwa futhi ibanjwe ngokunemba. I-40 Hz ingu-40 Hz, iyaqhubeka futhi izinzile phakathi nesikhathi sonke.

Imishini kaDidahealthy yakhelwe phezu kwalesi simiso, esiklanyelwe ukuletha amaza afanele emtholampilo — kufaka phakathi i-40 Hz — ngokunemba okudingwa ucwaningo. Bheka imininingwane ephelele yemishini lapha.

Lokho Ucwaningo Olungakakuqinisekisi

Ukwethembeka mayelana nokulinganiselwa kuyingxenye yokuthatha isayensi ngokungathi sína.

Ubufakazi obuqine kakhulu bokukhuthazwa kwe-40 Hz kanye ne-Alzheimer's pathology busavela kumamodeli ezilwane. Izivivinyo zabantu ziyaqhubeka futhi imiphumela yokuqala iyathembisa, kodwa izivivinyo ezinkulu ezilawulwa ngokungahleliwe kubantu azikaqedwa. Iphrothokholi engcono kakhulu - isikhathi esingakanani, kangaki, ngamandla angakanani - isanqunywa.

Lokho ucwaningo olukucacisayo yindlela: ukukhuthazwa kwe-gamma okungu-40 Hz kuhlanganisa izindlela zangempela zebhayoloji, ubufakazi buhambisana kuzo zonke izindawo zokucwaninga ezizimele, futhi insimu iya ekusetshenzisweni kwabantu ngokuzethemba okwandayo. Isayensi iqinile. Ukuthuthukiswa kuyaqhubeka.
