EEG Ubuchopho bomntu

Electroencephalography yindlela yophando ingqondo ngokusekelwe ubhaqo kwenzeka ebudeni ingqondo ebalulekileyo zombane umahluko enokwenzeka.

I yokuqala 1849 waqalisa ukufunda iinkqubo zombane ebuchotsheni D. Reymond, owaba ukuba ubuchopho unalo iipropati electrogenic, kunye luvo kunye nezihlunu. Ngowe-1913, Vladimir Vladimir Pravdich-Neminsky epapashwe ubuchopho electroencephalogram inja yokuqala, wamthwalisa eqala izifundo electroencephalographic. Kodwa irekhodi EEG ingqondo yokuqala ingqondo yomntu wabonakala kuphela ngo-1928, nto yafunyanwa Hans Berger, i wengqondo Austria.

kwidatha yobhaliso ye-EEG ingqondo lwenziwa yi electrode abakwiindawo kwiindawo ezithile entloko, kunye neendawo eziphambili ebuchotsheni. Kukho 16 ukuya kuma-24 (okanye ngaphezulu) ngokwandisa noshicilelo channels (iiyunithi) enokuthi ngaxeshanye ukubona umsebenzi zombane, electrode ezisisigxina. Irekhodi leyo kuthiwa electroencephalogram, kwaye umlinganiselo umsebenzi lilonke lombane izigidi luvo, nto leyo kakhulu simelwe nekhono of imizimba cell-luvo kunye luvo. Emva kokuba inkqubo kwenziwa kulungiswa EEG.

Amaxesha amaninzi, uphando ebhalisa utshintsho izingqisho, nganye yayo awo, reactivity, morphology kunye nesimo. Le Ukuxhaphaka ilandelayo Umfuno izingqisho: isingqisho Delta (ukuya Hz ezine), THETA isingqi (ezine ukuya kwezisibhozo elilodwa), isingqisho alpha (ezisibhozo-ezilishumi Hz) kunye beta-isingqi (ezilishumi elinesine kunye Hertz). physiologic Uninzi for abadala, cwaka, umntu ungalali yi isingqi alpha leyo emiselwe iinkophe buthotywe phezu Ezomva esithinzini ebuchotsheni. Noko ke, kukho iintlobo ezahlukeneyo norm komzimba, kuthathelwa ingqalelo imeko luvo kunye nobudala isigulane. Kuyo ubomi bomntu kwahluka eyahlukileyo etshintsha izingqisho azimisele phezu electroencephalogram.

Electroencephalography, okanye EEG ingqondo ibonisa imeko neuron, izakhiwo ingqondo subcortical, kwakunye nomgangatho intsebenziswano cortical-subcortical evumela ukuba ukufumanisa ubukho sisifo ebhekiswe, izilonda eyintsalela, abanye babe ezinxaxhileyo okwangoku yatyunjwa. Ukongeza, ubuchopho EEG inika ulwazi oluyimfuneko diagnostic malunga izinga nokwanda-luvo (luxilongo yobuntwana), utshintsho ingqondo kunye ukwenzakala ebuchotsheni, nakujoliso olutsha lwezidumbu, okanye umsebenzi nokuhlutha epileptiform. Kwakhona, le hlobo isifo ozakukuvumela ukuba uphathe ekuhambeni sifo, kwanokulungelelanisa unyango ukwenza naziphi iingqikelelo.

Oluneenkcukacha EEG sigqibo kunceda ukufumanisa uhlobo sokuwa, kwakunye umahluko une nezinye izifo paroxysmal ezifana migraine, niphele, ukushaya neentlekele yawo.

Le koviwo yalula ngokupheleleyo nibe. Ngethuba loviwo isigulane ehleli ngamehlo ivaliwe, ekhululekile, esitulweni tofotofo, t. E. Kwimeko uphaphama kwisixando sokwenziwa. Kwimeko EEG-komntwana, kuyimfuneko ukuba kunokumtshintsha uvavanyo yalula ubabikele oko kuza kwenzeka. Nomonde ngexesha lesifundo kufuneka nihluthe, kuba indlala zingachaphazela iziphumo EEG. Head kufuneka ihlanjwe ngocoselelo, eyenza i electrode adibane entlonzeni ezikumgangatho ophezulu. Ukongeza, iziphumo ixhomekeka kubudala yesigulane, iziyobisi athathiweyo, ubukho nongcangcazelo intloko namanqina, iziphene yaba lukakayi, ongaboniyo. Zonke ezi meko zingachaphazela ukutyhilwa esichanekileyo data EEG nokusetyenziswa ngakumbi.
