An electroencephalogram yeuropi inzira yekudzidza huropi nekubatsira kwema electrodes akabatanidzwa kumusoro. Vagashiri vanobata basa rejoelectric reropi uye vanorireurura muchimiro che sinusoid. Nzira yekuongorora hutano hwemagariro europi iye zvino haisi kuitika munzvimbo dzakasiyana-siyana, asiwo mumakiriniki emaguta uye emunharaunda, asi kure nemunhu wese anoziva kuti electroencephalogram yeuropi inoratidzei.
Chii chinonzi electroencephalogram inoratidza?
I electroencephalogram inoratidzira humwe hutano hwehutano panguva yekumuka, kurara, kushingaira kwebasa uye basa remuviri, nezvimwe. Nguva yeEEG inopera maawa maviri.
I electroencephalogram inopiwa kuvarwere vane zviratidzo zvinotevera:
- fainting;
- hypertension;
- headaches;
- kunetseka;
- vegetovascular dystonia ;
- osteochondrosis;
- chirwere chekupararira kwechiremba;
- kushushikana kwehope;
- neuroses;
- kuora mwoyo ;
- craniocerebral trauma;
- kunonoka mupfungwa uye kutaura kwekutaura kuvana;
- meningitis, encephalitis;
- anofungidzirwa tumarara kukura;
- mushure mekurohwa.
An electroencephalogram inotenderwa kusati kwamboitwa neurosurgic and after it. Asi pano kuti uise pahutano hweEEG kurapwa mune zvepfungwa, zvinopesana nedzidziso dzakawanda, hazvibviri.
Kugadziriswa kweuropi electroencephalogram
Kana kuongorora chirongwa ichi kunoratidza kuitika kwemaitiro emamwe marudzi, anopiwa ne thalamus, iyo inogonesa kushanda kwenheyo yenheyo. Pamusoro peEEG varipo:
- Alpha rhythm ine nguva yakawanda ye8 - 14 Hz, ichiratidzira nyika yekuzorora munguva yekumuka.
- Beta-rhythm, ine nguva yakawanda ye13 - 30 Hz, iyo inoratidza mamiriro ekuzvidya mwoyo, kuora mwoyo.
- Delta rhythm ine nguva yakawanda ye 0.5 - 3 Hz, inowanikwa panguva yokurara zvakadzika, asi yakanyorwa zvishoma uye yakamuka. Kana iyo delta rhythm inowanikwa mune zvose zvivako zveuropi, zvino inoratidza kukundwa kwenheyo yenheyo.
- Theta rhythm ine nguva yakakura ye4 - 7 Hz uye ukuru hwema 25 - 35 μV inowanzoonekwa kune vana, asi vari varwere vakura vanozviratidza panguva yekurara kwepanyama.
EEG inoguma kune vanhu vakuru vanoenderana nemirairo kana:
- muhutachiona hemispheres muitiro iwoyo wegetsi yemabasa;
- hakuna basa risina kujairika rinoputika;
- alpha uye beta rhythms predominate;
- apo inoratidzwa chiedza, pane nguva shomanana inopindura mune imwe nzvimbo yeuropi, asi kazhinji basa reropi rinoramba rakare.
