Cov Kev Ntsuas Hluav Taws Xob

Hluav taws xob ntsuas

Muaj nquag muaj hluav taws xob hauv cov paj hlwb, thiab nws yog los ntawm cov kev siv hluav taws xob uas tib neeg ua tiav ntau yam kev mob hauv lub cev. Lub tshuab electroencephalogram (saib) tuaj yeem tau los ntawm kev sau cov sij hawm sib txawv ntawm qhov peev xwm ntawm cov hluav taws xob theem. Cov mob neurological tuaj yeem kuaj tau thiab kho tau los ntawm kev kuaj thiab sau cov ntawv electroencephalogram.

Neurons nyob rau hauv lub hlwb raug da dej rau hauv ib qho tshwj xeeb extracellular kua (CSF), thiab qhov hluav taws xob ntawm cov nerves yuav sib npaug rau ib qho dipole. Yog tias txhua lub tsev me me sib npaug li ib lub dipole, qhov sib npaug ntawm txhua lub paj hlwb sib npaug yog qhov vector tag nrho ntawm txhua tus dipoles. Ua raws li qhov no dipole, yuav tsum muaj kev ntsuam xyuas. Ib qho kev siv electroencephalogram, los yog saib, yuav siv tau los ntsuas kev hloov ntawm qhov hluav taws xob muaj peev xwm ntawm lub hlwb cortex.

Siv cov electrocephalogram (saib) los nrhiav qhov txhab thiab kuaj pom tus kab mob, tsis yog los ntawm ib khub ntawm cov electrodes kom siv, tab sis siv ntau tshaj li cov hlau lead (ntau yam), raws li txawv mob thiab cov cai, txuas nrog lwm txoj kev, ntau yam nthwv dej, txheeb xyuas cov yeeb yam ntawm ntau yam kev sib tw thiab sib txuas nrog kev sib raug zoo thiab qhov kev kuaj kab mob, uas yuav tsum muaj lub hlwb muaj lub zog thiab sau ntawv, feem ntau hais, muaj 6, 16, 32.

Tam sim no daim ntawv thov ntawm lub hlwb cov khoom hluav taws xob

1. Kev sib tw EEG tshuab --- feem ntau siv cov ntaub ntawv soj ntsuam, feem ntau muaj 8 mus rau 16 hlau electrodes.

2. Machineless EEG tshuab --- EEG teeb liab sau rau hauv lub computer tom qab A / D hloov dua siab tshiab, thiab yog siv los ntawm qhov screen. Nws tseem muaj feem xyuam nrog 8 rau 16 hlau electrodes.

3. EEG topographical daim ntawv qhia --- Lub configuration yeej zoo ib yam li ntawm cov tshuab homeless EEG, tab sis tsawg kawg yog 16 hlau lead yuav tsum tau, thiab lub tshuab luam ntawv tau tso xim xim. Qhov sib tam tam sim no yog los sib sau ua ib lub tshuab tsis muaj ntaub ntawv EEG nrog cov koom haum EEG.

4. EEG monitor --- yuav pom EEG waveforms nyob rau ntawm lub sijhawm thiab tsis tu ncua, thiab muaj kev cia ua haujlwm thiab cov kev tswj cov ntaub ntawv, nyiam dua nrog kev ceeb toom.

5. EEG Holter - uas yog, cov ntaub ntawv EEG ntev mus ntev. Feem ntau nruab nrog 3 ~ 16 electrodes, nws muaj peev xwm muab khaws cia 24 H EEG Pib ntsais koj teeb.

6. EEG Analyzer - Muaj EEG Holter's qhov kev tshawb fawb playback analysis system thiab EEG tsom system feem ntau. Cov ntaub ntawv EEG ntev ntev (ntau tshaj 30 teev), nrog ntau dua 16 electrodes, nrog kev ntsuam xyuas ntau dua (lub sij hawm sau, zaus sau thiab airspace).
