Kodi electroencephalogram ya ubongo imasonyeza chiyani?

Electroencephalogram ya ubongo ndi njira yophunzirira ubongo mothandizidwa ndi magetsi omwe amapezeka pamutu. Ovomerezeka amagwira ntchito za ubongo ndikuzilemba mu mawonekedwe a sinusoid. Ndondomeko yodziwira kuti chikhalidwe cha ubongo sichikuchitika pokhapokha muzipatala zapadera, komanso m'zipatala zam'tawuni komanso m'tauni, koma palibe aliyense amene amadziwa zomwe electroencephalogram ya ubongo imasonyeza.

Kodi electroencephalogram imasonyeza chiyani?

Electroencephalogram imasonyeza momwe ubongo umakhalira panthawi yopuma, kugona, kugwira ntchito mwakhama ndi ntchito, etc. Kuchita kwa njira ya EEG ndi maola 1-2.

Electroencephalogram imaperekedwa kwa odwala omwe ali ndi mawonetseredwe otsatirawa:

• kukomoka;
• chowopsa;
• mutu;
• phokoso;
• zomera ;
• osteochondrosis;
• matenda a ubongo;
• zovuta za kugona;
• zosokoneza;
• khunyu ;
• chisokonezo;
• kuchepetsa kukulitsa maganizo ndi kulankhula mwa ana;
• meningitis, encephalitis;
• chokayikitsa chitukuko;
• pambuyo pa kupwetekedwa.

An electroencephalogram ndi yodalirika musanayambe kugwira ntchito yokhudza ubongo ndi pambuyo pake. Koma apa kuti tiike pa maziko a EEG matenda a maganizo, mosiyana ndi zomwe anthu ambiri amakhulupirira, n'zosatheka.

Kusintha kwa ubongo electroencephalogram

Podziwa kuti katswiri wamaphunziro amasonyeza kuti nthawi zonse zimakhala ndi zizindikiro za mtundu wina, zomwe zimaperekedwa ndi thalamus, zomwe zimatsimikizira kuti ntchito yoyamba yamanjenje ikugwira ntchito. Pa EEG alipo:

1. Alpha nyimbo ndi mafupipafupi a 8 - 14 Hz, akuwonetsera nthawi ya kupumulira pakutha.
2. Beta-rhythm, kukhala ndi maulendo 13 mpaka 30 Hz, omwe amasonyeza nkhawa, nkhawa.
3. Delta rhythm ndi mafupipafupi a 0,5 - 3 Hz, omwe amapezeka mu tulo tofa nato, koma amalembedwa mokhazikika. Ngati chiwonetsero cha delta chimawoneka m'zinthu zonse za ubongo, ndiye kuti zikutanthauza kugonjetsedwa kwa kayendedwe kabwino ka mitsempha.
4. Mtambo wa Theta wokhala ndi maulendo 4 mpaka 7 Hz ndi matalikidwe a 25 - 35 μV ndiwowoneka kwa ana, pamene odwala akulu amawonekera pa nthawi yogona.

EEG imapangitsa anthu akuluakulu kukhala ofanana ngati:

• mu ubongo wa hemispheres chitsanzo chomwecho cha magetsi;
• palibe zochitika zachilendo zopanda ntchito;
• zizindikiro za alpha ndi beta;
• pamene zimawoneka bwino, pamakhala nthawi yayitali m'madera ena a ubongo, koma kawirikawiri ntchito ya ubongo imakhala yachibadwa.
