Kuberekwa uye kurekodha kweEEG:
EEG inowanzowanikwa nemagetsi pamusoro pemusoro wemusoro.Nzira yekugadzirwa kweganda remusoro inowanzotendwa kuti: kana yakanyarara, maapical dendrites emasero epyramidal - yesero rose mu axis yemuviri wemasero ari mune polarized state;kana fungidziro ichiendeswa kune imwe mugumo wesero, inoita kuti magumo aite depolarized.Musiyano ungangoita musero unogadzira bipolar electric field system, ine ikozvino inoyerera kubva kune imwe mugumo kuenda kune imwe.Sezvo ese ari maviri cytoplasm uye extracellular fluid ine electrolytes, ikozvino inopfuurawo kunze kwesero.Ichi chiitiko chemagetsi chinogona kunyorwa uchishandisa scalp electrodes.Kutaura zvazviri, zvinogona kuchinja muEEG paganda remusoro isanganiswa yakawanda yakadaro bipolar electric fields.EEG hairatidzi kushanda kwemagetsi kwesero retsinga, asi panzvimbo pacho inonyora huwandu hwemabasa emagetsi emapoka akawanda emasero etsinga munharaunda yeuropi inomiririrwa nemagetsi.
Izvo zvakakosha zvikamu zveEEG: Iyo waveform yeEEG haina kurongeka, uye frequency yayo inoshanduka muhuwandu hwe1 kusvika 30 nguva pasekondi.Kazhinji iyi frequency shanduko inokamurwa kuita 4 mabhendi: iyo frequency ye delta wave ndeye 0.5 kusvika 3 nguva./ sec, iyo amplitude ndeye 20-200 microvolts, vanhu vakuru vanogona kungonyora iyi wave pavanenge vari muhope huru;iyo frequency ye theta wave ndeye 4-7 nguva pasekondi, uye amplitude inenge 100-150 microvolts, vanhu vakuru vanowanzorara Iyi wave inogona kunyorwa;theta uye delta waves dzinonzi pamwe chete mafungu anononoka, uye mafungu edelta nemafungu etheta haawanzo kunyorwa muvanhu vakasvinura;kuwanda kwemafungu ealpha ndeye 8 kusvika ku13 nguva pasekondi, uye amplitude ndeye 20 kusvika ku100 microvolts.Ndiwo mutinhimira wekutanga wemasaisai ehuropi emunhu mukuru, anoitika kana maziso akamuka uye akavharika;kuwanda kwemafungu e beta ndeye 14 kusvika ku30 nguva pasekondi, uye amplitude ndeye 5 kusvika 20 microvolts.Chiyero chekufunga chakafara, uye kutaridzika kwemafungu e beta kunowanzo ratidza kuti cerebral cortex iri mukunakidzwa.EEG yevana vakakwana yakasiyana neyevakuru.Vacheche vanotongwa neakadzika-amplitude anononoka mafungu, uye kuwanda kwemafungu ehuropi zvishoma nezvishoma kunowedzera nezera.
①α wave: frequency 8～13Hz, amplitude 10～100μV.Matunhu ese ehuropi ane, asi anonyanya kuoneka munharaunda ye occipital.Alpha rhythm ndicho chinhu chikuru cheEEG chiitiko muvakuru nevana vakura kana maziso avo akamuka uye akavharika, uye alpha wave rhythm muvana inooneka zvishoma nezvishoma nezera.
②β wave: frequency ndeye 14～30Hz, uye amplitude inenge 5～30/μV, inova pachena munzvimbo dzemberi, dzenguva uye dzepakati.Kuwedzera mukushanda kwepfungwa uye kufara kwepfungwa.Inenge 6% yevanhuwo zvavo vachiri nebeta rhythm muEEG yakarekodhwa kunyangwe vakagadzikana mupfungwa uye maziso akavharika, inodaidzwa kuti beta EEG.
③Theta wave: frequency 4～7Hz, amplitude 20～40μV.
④δ wave: frequency 0.5～3Hz, amplitude 10～20μV.Kazhinji inooneka pahuma.
