Yintoni i-electroencephalogram yobomi ebonisa?

I-electroencephalogram yengqondo yindlela yokufunda ingqondo ngokuncedisa i-electrodes ehlanganiswe entloko. Abamkeli babamba umsebenzi wezinto eziphilayo zeengqondo kwaye ziyirekhodile ngendlela yesonoid. Inkqubo yokufumanisa uhlobo lwesimo sengqondo esisetyenziswayo okwangoku ayiqhutywanga kuphela kumaziko akhethekileyo, kodwa nakwiikliniki zasezidolophini nakwizithili, kodwa kude nomntu wonke uyazi ukuba i-electroencephalogram yengqondo ibonisa ntoni.

I-electroencephalogram ibonisa ntoni?

I-electroencephalogram ibonisa isimo sesimo sengqondo ngexesha lokuvuka, ubuthongo, umsebenzi osebenzayo wengqondo kunye nomzimba, njl. Ubude benkqubo ye-EE ye-1-2 iiyure.

I-electroencephalogram inikwe izigulane zibonakaliso ezilandelayo:

• kutyhafa;
• xi nzelelo;
• intloko;
• zixhala;
• i-dystonia yemifuno ;
• osteochondrosis;
• ukukhubazeka kokujikeleza kwe-cerebral;
• izifo zokulala;
• neuroses;
• ukuhluthwa ;
• i-craniocebral trauma;
• ukulibaziseka ekuphuculweni kwengqondo nentetho kubantwana;
• i-meningitis, i-encephalitis;
• ku kro
• emva kwesifo.

I-electroencephalogram iyimfuneko ngaphambi kokusebenza kwe-neurosurgical kwaye emva kwayo. Kodwa apha ukubeka isiseko se-EEG ukuxilongwa kwezifo zengqondo, ngokuchasene neenkolelo eziqhelekileyo, akunakwenzeka.

Ukuchithwa kwengqondo ye-electroencephalogram yengqondo

Xa ukuchonga i-ingcali kubeka ingqalelo kwiimpawu ezithile zeentlobo ezithile, ezinikezwa yi-thalamus, eqinisekisa ukuba kusetyenziswa inkqubo ye-nervous central. Kwi-EEG zikhoyo:

1. I-Alpha isingqimba kunye nobunzima be-8 ukuya kwi-14 Hz, ebonisa isimo sokuphumla ngexesha lokuvuka.
2. I-Beta-rhyth, enexesha elinama-13 ukuya ku-30 ​​Hz, elibonisa isimo sokuxhalabisa, ukuxinezeleka.
3. I-Delta ishythm nge-frequency ye-0.5 - 3 Hz, eyenzeka ngexesha lokulala ngokukhulu, kodwa ibhalwe ngokukhawuleza kwaye ivuke. Ukuba isigqirha se-delta sibonakala kuzo zonke izakhiwo zobuchopho, ngoko kubonisa ukutshatyalaliswa kwenkqubo ye-nervous central.
4. I-rhythm enobukhulu be-4 ukuya kwi-7 Hz kunye nobukhulu be-25 ukuya ku-35 μV bubonakala kubantwana, ngelixa izigulane zabantu abadala zibonakalisa ngexesha lokulala ngokwemvelo.

I-EEG ibangela ukuba abantu abadala bahambelane nesiqhelo ukuba:

• kwi-hemispheres ye-cerebral yindlela efanayo yomsebenzi wombane;
• akukho misebenzi engavamile;
• Iimpawu ze-alpha kunye ne-beta zibalulekileyo;
• xa ebonakala ekukhanyeni, kukho impendulo emfutshane kwiindawo ezithile zobuchopho, kodwa ngokubanzi umsebenzi wengqondo uhlala uqhelekileyo.
