Nyob rau hauv neuroscience, ib qho excitatory postsynaptic muaj peev xwm yog lub peev xwm postsynaptic uas ua rau postsynaptic neuron ntau dua yuav tua hluav taws muaj peev xwm.
Dab tsi yog qhov ua rau muaj peev xwm postsynaptic hauv kev puas siab puas ntsws?
excitatory postsynaptic peev xwm (EPSP)
luv luv ntawm qhov sib txawv ntawm cov hluav taws xob hluav taws xob hla cov membrane ntawm cov neuron uas yog tshwm sim los ntawm kev xa cov teeb liab los ntawm cov neeg nyob sib ze neuron hla. lub synapse (kev sib tshuam tshwj xeeb) cais lawv … Sib piv inhibitory postsynaptic peev xwm.
Dab tsi yog qhov ua rau muaj peev xwm postsynaptic thiab dab tsi ua rau nws?
Ib qho excitatory postsynaptic muaj peev xwm (EPSP) yog ib ntus depolarization ntawm postsynaptic membrane tshwm sim los ntawm kev ntws ntawm cov ions zoo rau hauv lub xov tooj ntawm tes vim yog qhib cov ligand-sensitive channels.
piv txwv ntawm EPSP yog dab tsi?
Xav txog, piv txwv li, neuronal synapse uas siv glutamate ua tus xa xov… Yog li, EPSP nce qhov tshwm sim uas cov postsynaptic neuron yuav tsim muaj peev xwm ua tau, txhais cov synapse no ua excitatory.
Qhov txawv ntawm qhov kev ua kom muaj zog thiab qhov ua rau muaj peev xwm ua rau muaj zog yog dab tsi?
Ib qho kev xa tawm excitatory tsim lub teeb liab hu ua qhov ua tau zoo hauv cov neuron tau txais. Ib qho inhibitory transmitter tiv thaiv nws. … Qhov no txhais tau hais tias lawv nce qhov yuav tshwm sim uas cov neuron yuav tua qhov muaj peev xwm ua haujlwm Inhibitory neurotransmitters muaj inhibitory cuam tshuam rau neuron.
