Dopamine. Dopamine muaj cov teebmeem uas yog ob qho tib si excitatory thiab inhibitory. Nws yog koom nrog cov khoom plig hauv lub hlwb. Cov yeeb tshuaj xws li cov yeeb yaj kiab, yeeb yaj kiab, thiab cawv tuaj yeem ua rau nws nce qib hauv cov ntshav ib ntus.
Yuav ua li cas dopamine receptors yog excitatory?
Kev ua kom cov dopamine receptors tuaj yeem ua rau muaj kev ntxhov siab (D1, D5) lossis inhibitory (D2, D3, D4) cov lus teb hauv lub hlwb (Brown, 2015).
dopamine muaj qhov cuam tshuam qhov twg?
Dopamine (DA) ua lub luag haujlwm tseem ceeb hauv kev muab nqi zog thiab kev txav mus los hauv lub hlwb. Hauv txoj kev muab nqi zog, kev tsim khoom ntawm DA tshwm sim nyob rau hauv ventral tegmental cheeb tsam (VTA), hauv paj hlwb lub cev. Los ntawm qhov ntawd, nws tawm mus rau hauv lub nucleus accumbens thiab prefrontal cortex.
Lub paj hlwb twg yog nplua nuj nyob hauv dopamine?
Cov dopaminergic neurons uas tsim cov teeb liab molecule no nyob rau hauv lub hlwb ntawm substantia nigra thiab ventral tegmental cheeb tsamuas yog ob qho tib si nyob rau hauv lub midbrain nrog rau lub arcuate nucleus ntawm lub hypothalamus.
Cov neurotransmitters twg yog excitatory thiab uas yog inhibitory?
Glutamate yog thawj lub zog xa tawm hauv nruab nrab paj hlwb. Conversely, ib tug loj inhibitory transmitter yog nws derivative γ-aminobutyric acid (GABA), thaum lwm inhibitory neurotransmitter yog cov amino acid hu ua glycine, uas yog feem ntau pom nyob rau hauv tus txha caj qaum..
