Rau tias feem ntau cov neurons tau txais kev nkag los ntawm ob qho tib si excitatory thiab inhibitory synapses, nws yog ib qho tseem ceeb kom nkag siab meej meej cov txheej txheem uas txiav txim siab seb ib qho synapse excites lossis inhibits nws tus khub postsynaptic.
Puas yog neurotransmitter puas yog ob qho tib si excitatory thiab inhibitory?
Qee cov neurotransmitters, xws li acetylcholine thiab dopamine, tuaj yeem tsim ob qho tib si excitatory thiab inhibitory cuam tshuam nyob ntawm hom receptors uas muaj.
Tus neuron puas tuaj yeem tau txais cov lus zoo siab thiab ua rau tib lub sijhawm?
Ib leeg neuron tuaj yeem tau txais ob qho tib si excitatory thiab inhibitory inputs los ntawm ntau cov neurons, ua rau hauv cov membrane depolarization (EPSP input) thiab hyperpolarization (IPSP input). Tag nrho cov tswv yim no tau ntxiv ua ke ntawm axon hillock.
Hom neuron twg yog ob qho tib si inhibitory thiab excitatory?
Dopamine . Dopamine muaj cov teebmeem uas yog ob qho tib si excitatory thiab inhibitory. Nws yog txuam nrog nqi zog mechanisms nyob rau hauv lub hlwb.
GABA puas tuaj yeem ua rau inhibitory thiab excitatory?
Sib piv rau lub hlwb paub tab, uas GABA yog qhov tseem ceeb inhibitory neurotransmitter, hauv lub hlwb tsim GABA tuaj yeem ua rau excitatory, ua rau depolarization, nce cytoplasmic calcium, thiab ua haujlwm. muaj peev xwm.
