Magnetoencephalography

I-Magnetoencephalography (mag-NEE-toe-en-sef-uh-low-graf-ee) iyindlela yokuhlola umsebenzi wohloko. Ngokwesibonelo, ingahlola amasimu ama-magnetic avele emazingeni kagesi ebuchosheni ukuze ibonise izingxenye zobuchopho eziholela ekubanjweni kwezifo. Ingasiza futhi ekuboniseni indawo yezinto ezibalulekile njengokukhuluma noma umsebenzi wemisipha. I-Magnetoencephalography ivame ukubizwa nge-MEG.

Uma ukukhanda kuyadingeka, kungcono ukuthi amalungu eqembu lakho lokunakekelwa kwezempilo aqonde konke angakwazi ngengqondo yakho. I-MEG iyindlela engangenisi lutho yokuqonda izindawo zengqondo ezibangela ukubamba nokubamba okunethezeka futhi izindawo ezithinta imisebenzi yengqondo yakho. I-MEG iphinde isize iqembu lakho lokunakekelwa lithole izindawo zengqondo okufanele uzigweme. Idatha ehlinzekwa yi-MEG yenza kube lula ukuhlela ukukhanda ngokuqondile. Esikhathini esizayo, i-MEG ingase ibe usizo ekuxilongeni isiguli, ukulimala kokukhuluphala kwengqondo, isifo se-Parkinson, ukuwohloka kwengqondo, ubuhlungu obuhlala isikhathi eside, isifo sengqondo esivela esifweni se-liver nezinye izimo.

I-MEG ayisebenzisi ama-magnets. Kunalokho, i-test isebenzisa abavivisi abanozwakala olukhulu ukulinganisa ama-magnetic fields avela ebuchosheni bakho. Ayikho imingcipheko eyaaziwayo yokwenza la malinganiso. Noma kunjalo, ukuba nethusi emzimbeni wakho noma ezingutsheni zakho kungavimbela ukulinganiswa okuchaneka futhi kungalimaza abavivisi be-MEG. Iqembu lakho lokunakekelwa lihlola ukuthi awunalo ithusi emzimbeni wakho ngaphambi kwe-test.

Kungase kudingeke ukunciphisa ukudla namanzi ngaphambi kokuhlolwa. Kungase futhi kudingeke ukuyeka ukusebenzisa imithi yakho evamile ngaphambi kokuhlolwa. Landela imiyalo oyitholayo eqenjini lakho lokunakekelwa. Kumele uqambe izingubo ezanelisayo ezingenamaqhosha ensimbi, izikhafu noma ucingo. Kungase kudingeke ushintshe ube nge-gown ngaphambi kokuhlolwa. Ungagqoki amajezi, izesekeli zensimbi, kanye nokulungisa ubuso nezinto zezinwele ngoba kungase kube nama-compound ensimbi. Uma ukuba nezinto ezizungezile ikhanda lakho kukwenza ube nokukhathazeka, buza iqembu lakho lokunakekelwa mayelana nokuthatha i-sedative elula ngaphambi kokuhlolwa. Izingane ezincane nezingane zingase zithole i-sedation noma i-anesthesia ukuze zisize zihlale zizolile ngesikhathi se-MEG. Uchwepheshe wakho wezokunakekelwa kwezempilo angachaza izidingo nezinketho zengane yakho.

I-mehluko yokuhlolwa kwe-MEG ifanelana nekhanda njenge-helmet yebhayisikili. Iqembu lakho lokunakekelwa lihlola ukuhambelana kwekhanda lakho emishini ngaphambi kokwenza ukuhlolwa. Ilungu leqembu lakho lokunakekelwa linganika okuthile okufanele kubekwe ekhanda lakho ukuze kusize ukubekwa komshini kahle. Uhlala noma ulele uqonde ngesikhathi iqembu lakho lokunakekelwa lihlola ukuhambelana. Ukuhlolwa kwe-MEG kwenzeka ekamelweni eliwakhiwe ukuvimba umsebenzi we-magnetic ongalimaza ukuhlolwa. Uwedwa ekamelweni ngesikhathi sokuhlolwa. Ungakhuluma namalungu eqembu lokunakekelwa ngesikhathi nangemuva kokuhlolwa. Ngokuvamile, ukuhlolwa kwe-MEG akubuhlungu. Ochwepheshe bakho bezempilo bangenza i-electroencephalogram (EEG) ngesikhathi esifanayo ne-MEG. Uma kunjalo, iqembu lakho lokunakekelwa lizofaka izinzwa ezingezinye ekhanda lakho usebenzisa i-cap noma i-tape. Uma uzohlinzwa yi-MRI kanye ne-MEG, iqembu lakho lokunakekelwa cishe lizokuqala nge-MEG ukuze kunciphise amathuba okuthi ama-magnets aqinile asebenzisa kwi-MRI athinte ukuhlolwa kwe-MEG.
