Kuyini ukuhlolwa kwe-EEG?

I-electroencephalogram (i-EEG) ukuhlolwa okuqopha umsebenzi kagesi wobuchopho. Kuthola futhi kuqophe isikhathi esithathwayo ukuze i-pulse isuke endaweni eyodwa ebuchosheni iye kwenye noma kuqophe inani lezikhathi i-pulse enjalo eyenzeka ngazo phakathi nesikhathi esithile. I-electron impulses ingaqoshwa futhi ifundwe ngama-electrode abekwe ekhanda. Kuyinqubo yokuxilonga esetshenziselwa ukuphenya isifo sokuwa nezinye izifo zezinzwa, okuhlanganisa nezimila zobuchopho kanye nohlangothi.

Kunezizathu eziningi ezahlukene zokuthi kungani kungadingeka silinganise umsebenzi kagesi ebuchosheni bethu. Ezinye zazo zifaka phakathi ukwelashwa kwezokwelapha kanye nokuxilongwa kwezifo eziningi zobuchopho ezivamile nezikhubazayo ezifana nesifo sokuwa, i-autism, isifo sikaParkinson, ubuhlungu obungapheli, kanye nokucindezeleka, okuye kwahlotshaniswa nezinguquko emsebenzini we-EEG. Ikhono lokubona umsebenzi we-EEG lihlanganiswe nempendulo yesikhathi sangempela, okuvumela abantu ukuthi bafunde ukulawula izimo zabo zobuchopho ngokuzithandela. Le ndlela isetshenziswe ezinhlobonhlobo zezicelo, okuhlanganisa ukuqeqeshwa kokuphumula kanye nokuthola amakhono. Izimpawu ze-EEG zingasetshenziswa ukuthola amaphethini omsebenzi kagesi oxhumene nemicabango noma izinhloso ezahlukene.

"I-Electroencephalography (EEG) iqopha umsebenzi kagesi ekhanda. Ilinganisa ukuguquguquka kwamandla kagesi okubangelwa ugesi we-ionic ngaphakathi kwama-neurons obuchopho." 

Ku-EEG evamile, ama-electrode abekwa eceleni kwekhanda ukuze kulinganiswe lo msebenzi kagesi kusetshenziswa umshini we-electroencephalogram. Isignali eqoshiwe ifana kakhulu neyesikrini somntwana. Isignali idluliselwa emshinini we-electroencephalograph, oqopha idatha ephepheni noma esikrinini sedijithali.

Kokubili i-EEG kanye ne-MRI kuyizivivinyo eziwusizo ezinikeza ulwazi oluhlukile mayelana nobuchopho. Ukuhlolwa ngakunye kunamandla nobuthakathaka bakho, kodwa akukho okungcono kunokunye okuphelele.

Kungenzeka, kodwa hhayi njalo. I-EEG ejwayelekile ayiboni izimila zobuchopho njengoba ezinye izinhlobo zezimila zobuchopho kuphela ezibonakala ku-EEG. Izici eziningi ezifana nosayizi nendawo yesimila, ukuthi sikhula ngokushesha kangakanani, kanye nomehluko phakathi kweziguli kudingeka kucatshangelwe ngaphambi kokuba kufinyelelwe esiphethweni.

I-EEG ingabona izinguquko ezithile ekukhathazekeni, ngakho-ke ibizwa ngokuthi isilinganiso esingaqondile sokukhathazeka. Uhlobo locwaningo olwenziwe lubonisa ukuthi kukhona ubudlelwano phakathi kwe-EEG nokukhathazeka. Kodwa imiphumela ayicacile ngokwanele ukuthi abacwaningi namuhla basebenzise i-EEG njengethuluzi lokuxilonga eliqondile lokulinganisa ukukhathazeka. Izifundo ezenziwe zincane kakhulu, futhi akukho "phawu lokukhathazeka" olucacile ku-EEG.

Ngamafuphi, yebo, uma kunemininingwane eyanele, kungenzeka. Lo mbono usekelwe emaphethini okusebenza ngaphakathi kobuchopho. Uma ukuxhuzula kwenzeka ngezikhathi ezithile futhi kuvamile, njalo lapho kwenzeka, kuzoba nephethini yokuqala engatholakala uma iphinda ekurekhodweni kwe-EEG. Kumane nje kufunwa iziqongo endaweni efanayo emjikelezweni njalo.

Ama-EEG enziwa lapho isiguli sivukile. Umuntu akanakuthola i-EEG enembile lapho isiguli silele njengoba amagagasi obuchopho ehla kakhulu; ngakho-ke, isiguli sidinga ukuhlala siphapheme kuze kube yilapho zonke izilinganiso (kufaka phakathi i-Fp1, i-Fp2, i-C3, i-C4, njll.) seziqediwe.

Yebo, ungakwazi. Isizathu salokhu yilapho umuntu ekhululekile lapho edla ngaphambi kokufakwa emshinini we-EEG; kuvumela ukuziphatha kwamaza obuchopho bakhe ukuthi kuhambisane kakhulu nalokho abantu abakucabanga ukuthi "kujwayelekile." Ngamanye amazwi, uma umuntu ehlolwe ngesikhathi ezila ukudla bese ephinda futhi ngemva kokudla, imiphumela ingaba ehluke kakhulu.
