Cov synaptic ncua yog vim lub sij hawm tsim nyog rau kev tso tawm, nthuav tawm thoob plaws lub cleft, thiab khi nrog receptors ntawm postsynaptic membrane. Tshuaj synaptic kis tau tus mob feem ntau yog ib txoj kev. Hluav taws xob synaptic Kev sib kis yog kho los ntawm cov qauv tshwj xeeb hu ua qhov sib txawv junctions (Fig.
Tom qab ntawd, ib tus kuj tseem yuav nug, qhov kev ncua sijhawm sib kho yog dab tsi?
Synaptic qeeb . lub sijhawm tsim nyog rau kev coj ua ntawm lub teeb liab hla a synapse ; qhov ncua nruab nrab ntawm kev tuaj txog ntawm lub paj hlwb ntawm qhov kawg ntawm presynaptic fiber thiab pib ntawm lub peev xwm postsynaptic.
Ib sab saum toj no, dab tsi ua rau synapses tua hluav taws? Ntawm a synapse , ib qho neuron xa xov mus rau lub hom phiaj neuron-lwm lub xov tooj. Hauv tshuaj synapse , ib qho kev ua muaj peev xwm ua rau presynaptic neuron tso tawm neurotransmitters. Cov molecules khi rau receptors ntawm lub cell postsynaptic thiab ua rau nws ntau dua los yog tsawg dua. hluav taws muaj peev xwm ua tau.
Ib yam nkaus, tib neeg nug, qhov kev ncua sijhawm synaptic tshwm sim qhov twg?
Synaptic ncua yog txhais tau tias yog lub sij hawm ncua ntawm lub ncov ntawm sab hauv tam sim no los ntawm presynaptic membrane thiab pib ntawm sab hauv tam sim no los ntawm postsynaptic membrane.
Dab tsi yog txheej txheem ntawm kev sib kis synaptic?
Synaptic kis tau tus mob yog txheej txheem los ntawm ib qho neuron sib txuas lus nrog lwm tus. Cov ntaub ntawv tau dhau los ntawm axon ntawm neuron raws li hluav taws xob impulse hu ua kev ua tau zoo. Nws yuav tsum hla lub synaptic qhov sib txawv ntawm presynaptic neuron thiab tom qab synaptic hlwb.

Dab tsi yog qhov txaus ntshai rau kev kho qhov txhab qeeb?
Kev kho qhov txhab tuaj yeem ncua los ntawm cov txheej txheem uas ua rau me me lossis tsis muaj kev cuam tshuam ncaj qha rau qhov chaw ntawm qhov txhab nws tus kheej. Cov no suav nrog hnub nyoog, hom lub cev, kab mob ntev, tiv thaiv kab mob, noj zaub mov zoo, kho hluav taws xob, thiab tsis muaj ntshav txaus. Hnub nyoog
Dab tsi ua rau lub plab zom mov qeeb?
Qee cov tshuaj, xws li tshuaj tua kab mob opioid, qee cov tshuaj tiv thaiv kev nyuaj siab, thiab ntshav siab thiab tshuaj tsis haum, tuaj yeem ua rau lub plab zom mov qeeb thiab ua rau cov tsos mob zoo sib xws. Rau cov neeg uas twb muaj gastroparesis, cov tshuaj no yuav ua rau lawv tus mob hnyav dua
Lub chaw ua pa twg ua rau ua pa qeeb qeeb thaum txhawb?
Transection II, hauv qab ntawm PNC tab sis saum toj no apneustic center (APC), ua rau qeeb, sib sib zog nqus pa nrog vagi tsis zoo tab sis apneusis (sustained inspiration) los yog apneustic ua pa (nce inspiratory lub sij hawm) thaum lub vagi raug txiav
Dab tsi cuam tshuam rau synaptic efficiency?
Ib yam li ntawd, peb muaj lub tswv yim intuitive ntawm yam uas cuam tshuam rau synaptic efficiency. Yog li, yog tias tso tawm qhov tshwm sim lossis tus naj npawb ntawm quanta nce ntawm qhov muab synapse, nws qhov ua tau zoo kuj yuav nce ntxiv. Yog li, yog tias cov tswv yim presynaptic muaj zog, qhov tshwm sim ntawm qhov tau txais '1' raws li cov zis postsynaptic yuav nce
Kev qeeb qeeb txhais li cas ntawm EEG?
Focal Slowing Focal qeeb ua haujlwm ntawm EEG yog qhov qhia txog kab mob ntawm lub paj hlwb ntawm thaj tsam hauv qab ntawm lub paj hlwb. Kev qeeb qeeb tuaj yeem ua tsis sib xws lossis tsis tu ncua, nrog kev ua haujlwm tsis tu ncua lossis qeeb qeeb feem ntau qhia tau tias muaj kev cuam tshuam loj heev hauv qab focal cerebral dysfunction
