Qee lub ntsiab lus: Quantal content (m): (saib lub ntsiab lus ntawm nplooj ntawv thawj)=quantal naj npawb: tus naj npawb ntawm quanta uas tau tso tawm, ntsuas los ntawm qhov loj ntawm epp hauv mV. Nws yog modulated pre-synaptically los ntawm kev hloov transmitter tso tawm. … Nws yog modulated post-synaptically los ntawm kev hloov cov lus teb rau transmitter tso tawm.
Koj suav cov ntsiab lus li cas?
Peb tsuas tuaj yeem kwv yees qhov nruab nrab ntawm cov ntsiab lus, m, los ntawm kev faib qhov nruab nrab EPP amplitude los ntawm qhov txhais tau tias MEPP amplitude. Nws hloov tawm tias peb tseem tuaj yeem kwv yees qhov kev faib tawm ntawm amplitudes yog tias peb xav tias n loj heev (n>>p) thiab p yog me me (p<<1).
Yuav ua li cas cuam tshuam cov ntsiab lus ntau?
Qhov kho kom haum ntawm qhov evoked synaptic teb tuaj yeem siv los xam cov ntsiab lus nruab nrab. Saturation thiab desensitization ntawm postsynaptic receptors yog lwm yam uas yuav cuam tshuam qhov loj thiab cov duab ntawm postsynaptic tam sim no.
Kev tshuaj ntsuam quantal yog dab tsi?
Kev tsom xam ntau yog tus txheej txheem txheeb cais siv los cais cov txheej txheem ntawm kev sib txuas lus sib txuas thiab lawv cov kev hloov kho(Del Castillo thiab Katz, 1954; Boyd thiab Martin, 1956).
Vim li cas neurotransmitter tso tawm quantal?
Quantal neurotransmitter tso tawm mechanism
Ib tug quanta yuav randomly diffuse mus rau hauv lub synapse thiab ua rau ib tug tom ntej MEPP. … Kev nkag mus ntawm calciumions yuav ntxiv depolarize sab hauv ntawm lub axon davhlau ya nyob twg thiab yuav teeb liab quanta nyob rau hauv lub axon davhlau ya nyob twg los khi rau lub presynaptic membrane.
