Simply put, wetin na dis MEG?
MEG, ɔ Magnetoencephalography, na tɛst we de mɛzhɔ di rili subtil magnɛtik fil dɛm we ilɛktrik signal dɛn we wi bren sɛl dɛn de mek de mek. Fɔ tɔk di kɔrɛkt tin, dis na we fɔ mek di bren map di wok we wi bren de du.
Di bɛst pat na dat i nɔ de mek pɔsin fil pen atɔl ɛn i nɔ de ambɔg pɔsin. Dis min se dɛn nɔ de yuz nidul, dɛn nɔ de kɔt am, ɛn yu nɔ de gɛt ɛni raytin lɛk ɛkstrem rayt. MEG na di mכst advans mεtכd na di wכl fכ rεkכd εn evaluate di bren aktiviti.

apat frכm dat, MEG na wan tin we rili impɔtant pan sayɛns risach fɔ mek pɔsin ɔndastand mɔ bɔt aw mɔtalman bren de wok.
Aw dis mashin de wok?
I rili simpul. di nyuron dεm na wi bren de kכmכnik wit dεn wan dεm bay we dεn de mek sכm sכm ilektrikal vכltεj dεm. We dɛn ilɛktrik kɔrɛnt ya de flɔ, dɛn kin mek magnɛtik fil rawnd dɛn.
Di MEG mashin de yuz pas 300 sɛns dɛn we rili sɛnsitiv , we dɛn kin put pan wan tin we tan lɛk ɛlmɛt we yu kin wɛr na yu ed, fɔ no, rikodɔ, ɛn analayz dɛn magnɛtik fil dɛn ya. Dɛn sɛns ya so sɛnsitiv dat dɛn kin pik ivin di smɔl smɔl magnɛtik fil dɛn we de kɔmɔt na wi bren. Dɛn kɔl dɛn sɛns ya SQUID (superkɔndukt kwantum intafɛreshɔn divays dɛn).
dis sεns dεm εn spεshal kכmpyuta softwεa de wok tכgeda fכ rεkכd yu bren aktiviti milisekכnd bay milisekכnd, if yu sidon כ de du sכmtin (e.g., luk pikchכ כ rid wכd dεm). fכ finish, dis infכmeshכn de kam togεda wit wan imej fכ yu bren, we de sho na kכmpyuta skrin lεk "map" we de sho us pat dεm na yu bren de aktv.
Aw fɔ pripia fɔ di MEG tɛst?
Yu dɔktɔ go gi yu ɛni spɛshal instrɔkshɔn we yu nid bifo dis tɛst.

Wetin kin apin we dɛn de du di tɛst?
di we aw dεn de du MEG tεst kin difrεn sכmtεm dipכnt pan di rizin fכ am, bכt i kin go sכmtin lεk dis.
1. Pripia: Yu go pul ɔl di mɛtal tin dɛn na yu bɔdi ɛn put di ɔspitul gɔn.
2. Fɔ yɔŋ pikin dɛn: Fɔ smɔl pikin dɛn, i kin nid fɔ gi dɛn mɛrɛsin we de mek dɛn fil fayn ɔ we dɛn de tek jenɛral anestezi, bikɔs i kin at fɔ mek dɛn kɔntinyu fɔ de we dɛn de du di tɛst.
3. Pozishɔn: Mekɔp di rayt pozishɔn we yu ed de we yu kɔmpia am to di ɛlmɛt, ɛn put tri ɔ 4 smɔl posishun kɔyl dɛn wit tɛmporari tep na tri ɔ 4 say dɛn na yu ed.
.
5. Sidɔm fɔ di tɛst: Dɔn dɛn go mek yu sidɔm na spɛshal chia we dɛn kɔnɛkt to di MEG mashin, ɔ dɛn go mek yu ledɔm na bed.
6. Fɔ wɛr di ɛlmɛt:Naw, dɛn dɔn put di ɛlmɛt wit di MEG sɛns dɛn na yu ed. Dis kin ridyus di risk fɔ gɛt klaustrophobia. Fɔ mek yu gɛt di bɛst rizɔlt, kip yu ed nia di ɛlmɛt as yu ebul.
7. We dɛn de du di tɛst: Sɔntɛnde dɛn go aks yu fɔ sidɔm stil, ɛn yu kin ivin slip. We dɛn de skan yu bren, dɛn go aks yu fɔ du smɔl smɔl tin dɛn lɛk fɔ rid wɔd dɛn na skrin, fɔ ansa kwɛstyɔn dɛn, ɔ fɔ prɛs bɔtin. Sɔntɛnde, dɛn kin gi yu finga smɔl ilɛktrik tin fɔ no aw yu bren de ansa. Dis kin fil lɛk se yu de tik smɔl, bɔt i nɔ kin mek yu fil pen.
8. Kɔmyunikeshɔn: Di tɛst rum gɛt intakɔm ɛn vidio sistem, so yu kin tɔk to di tɛst tɛknishian ɛni tɛm.
Dis ɔl tɛst kin tek lɛk wan ɔ tu awa so.
Wetin kin apin afta di tɛst?
If dɛn gi yu ɔ yu pikin mɛrɛsin fɔ mek yu fil fayn, di wan dɛn we de wok na yu pikin go de wach yu fɔ lɛk af awa to tu awa so. Yu go nid pɔsin fɔ ɛp yu fɔ go na os.
If yu nɔ gɛt sɛdate, prɔblɛm nɔ de. Yu kin kɔntinyu fɔ du di tin dɛn we yu kin du ɔltɛm jɔs afta di tɛst dɔn.
No risk nɔ de we dɛn no bɔt we gɛt fɔ du wit di MEG tɛst. Na tɛst we rili sef.
Wetin na di difrɛns bitwin MEG, MRI ɛn EEG?
Pan ɔl we dɛn kin du ɔl dɛn tri tɛst ya na di bren, di tin dɛn we dɛn kin mɛzhɔ ɛn gi wi difrɛn.

Sɔntɛnde, dɔktɔ dɛn kin jɔyn di infɔmeshɔn we dɛn kin gɛt frɔm ɔl tu di MEG ɛn MRI tɛst dɛn fɔ mek wan map we de wok fɔ sho aw di bren de wok. Dɛn kɔl dis MSI (Magnetic Source Imaging).
Mɛsej we dɛn kin kɛr go na os
- MEG na tɛst we nɔ gɛt pen, we nɔ de du raydio, ɛn we rili sef we de map di wok we di bren de du.
- Dɛn kin yuz dis mɔ fɔ no di rayt say we di sik de ɛn fɔ plan fɔ du ɔpreshɔn pan in bren .
