Microelectrode arrays ntes thaj chaw muaj peev xwm lossis kev ua haujlwm thoob plaws tag nrho cov pejxeem, nrog cov ntaub ntawv ntau dua cov ntsiab lus hauv ib qhov zoo, tshawb xyuas cov qauv kev ua ub no uas yuav txwv tsis pub cov kev soj ntsuam ib txwm muaj xws li thaj clamp electrophysiology uas soj ntsuam ib leeg ntawm tes xws li neuron.
Yuav ua li cas ntau lub tshuab hluav taws xob ua haujlwm?
Multi-electrode array yog ib qho array ntawm microscopic electrodes faib hla thaj chaw me me nyob rau hauv qab ntawm iav los yog yas multi-zoo phaj lossis ib lub qhov dej (chip). Cov hluav taws xob hluav taws xob, xws li cov neurons lossis cardiomyocytes, tuaj yeem raug coj mus kuaj dua cov electrodes ua cov sib txuas sib txuas hauv lub sijhawm.
Koj siv microelectrode li cas?
Ib microelectrode yog ntxig rau hauv lub hlwb lossis ib sab ntawm lub paj hlwb ntawm kev txaus siab thiab tam sim no yog siv ntawm taw zaus thiab sijhawm. Cov electrode elicits muaj peev xwm ua tau los ntawm kev hloov qhov chaw extracellular xws li voltage-gated ion channels qhib, depolarizing lub neuron.
Utah array siv rau dab tsi?
Utah arrays tsis tau siv rau kev kaw, tab sis kuj rau lub hom phiaj txhawb nqa. Piv txwv li, Tabot et al. induced tactile sensations nyob rau hauv tes los ntawm lub hom phiaj neural stimulation nrog Utah arrays implanted nyob rau hauv lub somatosensory cortex, raws li illustrated nyob rau hauv daim duab.
microelectrode kaw yog dab tsi?
Qee zaum cov kws phais neeg txheeb xyuas cov qauv hauv hlwb los ntawmsiv cov txheej txheem hu ua microelectrode kaw. Ib qho hluav taws xob, thaum kawg ntawm cov hlau zoo heev, tau dhau los ntawm ntau qhov chaw ntawm lub hlwb, qhov twg nws kaw cov qauv hluav taws xob los ntawm ib puag ncig lub hlwb cov qauv.
