Bafuputsi ka U.S. -na le mokhoa o mocha le o ntlafetseng ya bakeng sa ho tseba likarolo le ho sireletsa boko mosebetsi bakuli elang hloko le mothating oa ho feta neurosurgery - ka Cooling tse nyenyane, localized libaka boko ho mo kena hanong ka nakoana sebetsang bona le e lekanye libakeng tse hlokehang bakeng sa lentsoe ho botjwa le ho nako ea ho bua. Ba hlalosa mokhoa ona o bona, 'me u hlalose kamoo sebelisa ho fuputsa boko mekgwa boo tlhahiso ea puo e buuoang, thutong e ntjha feela e hatisitsoeng koranteng ea Neuron.

Lipale tse buang ka batho ba lulang ba falimehile nakong ho buoa boko hlaha kamehla mecha ea litaba. A 2008, ka mohlala, bulwa litaba multiple tlaleha hore tsomo Bluegrass sebini Eddie Adcock eseng feela lula elang hloko, empa hape phethile Banjo hae, nakong ea opereishene tse tharo le halofo ho tšoara ka letsoho tremor. Le December qetela, ho ne ho amoheloa litlaleho tse tšoanang tse mabapi le Sepanishe jese sebini Carlos Aguilera, ba phethile saxophone hae ho pholletsa le e tshebetsong 12 lihora ho tlosa hlahala bokong.

mekgwatshebetso ya jwalo hangata hlalosoa e le "makatsang,"" Revolutionary," 'me, Ka linako tse ling, "Lik'hamera tsena mehlolo." Ha e le hantle, lingaka tse buoang tse 'nile sebetsa ho boko ea bakuli elang hloko ka bang lekholo ka lilemo tse: mokhoa oo o ile ntshetswa pele a 1920s ea ke le pula-maliboho ea methapo ea kutlo Canada Wilder Penfield, e le tsela ea ho fumana ea sa tloaelehang boko dinama tse nyenyane tse etsang hore tsoeroe ke sethoathoa sethoathoa.

Penfield sebelisoa li-electrode ho susumelletsa holim 'a boko bakuli ba hae', 'me ka boomo' na a li falimehile nakong etsa opereishene e le hore ba tlalehe liphello tsa tlhotlheletso ka morao ho eena. Ke Stimulating libakeng tse haufi le dinama tse nyenyane tse e sa tloaelehang, o ne a khetholla dinama tse nyenyane tse e bakang e leng sethoathoa le hoja ba ne qeto e leng oa libakeng tse potolohileng li habohlokoa hore mesebetsi ea bohlokoa joaloka ho bua le motsamao. Ka tsela ena, o ne a tlosa linama tse sa tloaelehang ntle baka tšenyo leha e le efe peeletso.

mokhoa oo o Penfield ea tlhotlheletso cortical o ntse o sebelisoa haholo lilemong kajeno empa, a batla makatsang, ka boeona lakalisa tsoeroe ke sethoathoa sethoathoa. Mokhoa oo o le lecha jarelang ha ho ipeha kotsing joalo. ntshetswa pele ke Michael Long ea New York University o Langone Medical Center le metsoalle ea hae, e haha ​​pele ho mokgwa wa ea pejana hore sebelisoa probes tsidifatso ho ithuta boko circuitry le boikarabelo ba ho tlhahiso a pina lithaha qoaha.

Long le metsoalle ea hae o ile a sebelisa mochine o tshwanang tsidifatso hodima 16 bakuli ba hlahlojoa bakeng ts'ebetso ea buoang methapo ea kutlo ho tšoara mokolang lithethefatsi manganga bona sethoathoa. Le bakuli tlas'a thethefatsa selehae, bafuputsi sebelisoa sesebediswa ho pholile 42 libaka discrete boko, tseo kaofela ha tsona li 'nile tsa pele e neng e tlatselletsa kaha tlhahiso ho bua, e ka bang ka 10°C mong le e mong. Ho sa le joalo, bakuli ba ne ba kōptjoa hore ba pheta matsatsing a beke, kapa ka tsela e itekanetseng khoele sa dinomoro, e le hore mosebetsi oa bona oa ho bua ka dirwa ditekolo ha a ntse a mong le e mong tikolohong eo e ile folisoa.

Tsidifatso interrupts mosebetsi lisele tse, 'me maemong a mang, bafuputsi ba ile ba fumana hore ho kena-kenana le bokhoni ba bakuli ho bua, slowing le blurring puo ea bona. le phello ena e ne e ba nakoana feela, Leha ho le joalo - boko mosebetsi khutlela setloaeling hang ka mor'a hore sesebediswa Cooling a tlosoe boko, 'me bohle 16 bakuli o ile a hlaphoheloa ho tswa ts'ebetso ea bona ntle le litla-undesired lehlakoreng kapa mathata a mang.

Liphello e tiisa fumanoeng ke pelenyana hore libakeng tse entsoeng ka boko ho akarelletsa tlhahiso ho bua ba boholo koalloa ho ea Lefatše le letšehali, 'me ba fana ka leseli le ncha ka hore na boko bo hlahisa puo e. ka ho toba, Cooling karolo khethehileng tsa ka ho le letšehali enjene cortex fetoloa boleng ba lipuo tsa bakuli ', athe Cooling ea Broca a Area ka sala lobe ya ntango fetoloa nako ea ho bua bona.

These results shows that the motor cortex directs the muscle movements in the lips and tongue that are required for articulating speech, whereas Broca’s Area is needed for executing these movements in their proper sequence.

“This study confirms that cooling is a safe and effective means of protecting important brain centers during neurosurgery," re Long. "[It] also represent['s] a major advance in the understanding of the roles played by the areas of the brain that enable us to form words.”
