EEG yeBreat Brain

Electroencephalography inzira yekudzidza uropi hunoenderana nekunyorwa kwechiyamuro mune zvigetsi zvemagetsi zvinobuda mumagariro europi.

Wokutanga muna 1849 akatanga kudzidza magetsi emagariro ehupfungwa D. Raymond, uyo akaratidza kuti uropi hune electrogenic properties, pamwe nemitsipa nemisungo. Muna 1913, VV Pravdich-Neminsky yakabudisa electroencephalogram yekutanga yeruzivo rwechija, kuisa kutanga kwe electroencephalographic zvidzidzo ikoko. Asi rekutanga reEEG rehupfungwa hwevanhu rakaratidzwa muna 1928 chete, rakagamuchirwa naHans Berger, chipatara cheAustria.

IEEG yeuropi inonyorwa uchishandisa magetsi anowanikwa kune dzimwe nzvimbo dze musoro, achifunga nezvezvikamu zvikuru zveuropi. Yakapiwa kubva pa16 kusvika ku24 (uye kupfuura) kuwedzera-kurema chiteshi (mabheji), iyo inobvumira kuburitsa panguva imwechete yemagetsi, ichigadziriswa nema electrode. Nhoroondo inoguma inonzi electroencephalogram, uye inoratidzira yehuwandu hwemagetsi ese emamirioni eetsuroni, ayo anonyanya kuratidzwa nemakumbo emitumbi yemasero emasero uye dendrites. Mushure mekugadzirisa, EEG inotsanangurwa.

Kakawanda panguva yekuongorora, kuchinja kwemitambo kwakanyorwa, iyo ine marefu, reactivity, morphology uye mavara. Kune zvirevo zvinotevera zvinowanikwa mumhanzi: delta rhythm (kusvika kune Hertz ina), theta rhythm (mana kusvika hupfumi Hertz), alpha rhythm (masere kusvika gumi nematatu Hertz) uye beta rhythm (gumi nemana kana kupfuura Hertz). Muviri wepamusoro kune munhu akakura, akadzikama, asingagoni kurara ndiye alpha rhythm, iyo inotsanangurwa apo maofidi anoderedzwa pamusoro pemaruva ekupedzisira europi. Zvisinei, kune marudzi akasiyana-siyana emitemo yepanyama inofunga nezvekutya kwenyika nezera remurwere. Muhupenyu hwose hwomunhu, electroencephalogram inoshandiswa kutsanangura kusiyana kwakasiyana-siyana kwehutano shanduko.

Electroencephalography, kana EEG yeuropi, inoratidza hutano hwehutachiona hwemakumbo, maitiro ehupfungwa ehutachiona, nehutano hwekubatana kwekortical-subcortical, iyo inobvumira kutsvaga kuvapo kwemaitiro ekudzivirira, kuparara kwekugarisa, uye kumwe kusakanganiswa kusingaoneki. Mukuwedzera, EEG yeuropi inopa hutano hunofanirwa kuongorora huwandu hwekutsvaga kwehutachiona hwehutano (hwekutsvaga muhutano), kuchinja kwechirwere uye zvipembenene zveuropi, pathological foci, epileptiform kana basa rekufa. Uyewo, rudzi urwu rwekuongororwa runokubvumira kutevera nzira yechirwere, shandura kurapwa uye kuita chero uprofita.

Tsanangudzo yakajeka yeEEG-yekupedzisira inobatsira kunyatsoongorora chirwere chekushaya chirwere, uyewo mukusiyanisa kwezvimwe zvirwere zvinokonzerwa neparoxysmal, zvakadai semigraine, syncope, panic kushungurudzwa uye zvinokonzera zvinomera.

Iyi kuongororwa haina chakanaka uye haina chakaipa. Penguva yekuongorora, murwere anogara nemeso ake akavharika, akasununguka, mune chigaro chinotendesa, kureva, mune mamiriro ekusauka. Mune nyaya yeEEG, mwana, anofanirwa kugutsikana nekusava nemhosva kwehuongorori uye anotaura kuti chaizvoizvo zvichaitika. Murwere panguva yekudzidza anofanira kudyidzwa, nokuti kunzwa nzara kunogona kukanganisa migumisiro yeEEG. Musoro unofanirwa kushambidzwa, izvo zvichaita kuti kusangana kwe electrodes nechepalp kuwedzere kufanirwa. Mukuwedzera, zvigumisiro zvinoenderana nezera remurwere, mishonga inotorwa, kuvapo kwekudengenyeka kwemusoro nemakumbo, skull defects uye kutadza kuonekwa. Zvose izvi zvinogona kukanganisa kududzirwa kwakakwana kweEEG data nekushandisa kwavo zvakare.
