Qhov sib txawv tseem ceeb ntawm neurogenesis neuroplasticity thiab neuroregeneration yog tias neurogenesis yog hais txog kev tsim cov neurons tshiab hauv lub hlwb thaum neuroplasticity hais txog lub hlwb lub peev xwm los kho nws tus kheej los ntawm kev sib txuas neural tshiab thoob plaws hauv lub neej thiab neuroregeneration hais txog regrowth lossis kho cov paj hlwb, hlwb los yog cov khoom ntawm tes.
Kev raug mob hauv lub paj hlwb tuaj yeem ua rau cov kab mob neurodegenerative xws li Alzheimer's kab mob, Parkinson's disease, amyotrophic lateral sclerosis, ntau yam sclerosis thiab ntau yam kab mob atrophy. Peb lub paj hlwb tsuas muaj peev xwm kho tau xwb. Neurogenesis, neuroplasticity thiab neuroregeneration yog peb cov txheej txheem tseem ceeb cuam tshuam nrog cov paj hlwb. Neurogenesis yog tsim los ntawm cov neurons tshiab los ntawm neural qia thiab progenitor hlwb. Neuroplasticity yog lub hlwb lub peev xwm hloov tau thaum neuroregeneration yog regrowth lossis kho cov paj hlwb.
Neurogenesis yog dab tsi?
Neurogenesis yog cov txheej txheem uas cov neurons tshiab tsim nyob rau hauv lub hlwb los ntawm neural qia thiab progenitor hlwb. Nws yog ib qho tseem ceeb ntawm cov txheej txheem thaum lub sij hawm embryonic txoj kev loj hlob, thiab nws yuav siv qhov chaw ntawm tus nqi siab dua. Txawm li cas los xij, neurogenesis kuj tshwm sim tom qab yug me nyuam hauv qee qhov ntawm lub hlwb, thiab nws txuas ntxiv mus rau tag nrho lub neej. Tab sis tus nqi poob qis nrog kev laus.
Daim duab 01: Neurogenesis
Cov neural qia hlwb faib tsis tu ncua thiab tsim cov hlwb neural progenitor. Neural progenitor cells sib txawv rau hauv cov neurons tshwj xeeb. Ntxiv mus, neural qia hlwb sib txawv rau hauv glial progenitor hlwb uas ua rau cov hlwb glial xws li astrocytes, oligodendrocytes thiab microglia. Cov neeg mob uas raug mob los ntawm Alzheimer's disease lossis Parkinson's disease tau cuam tshuam cov neurogenesis. Cov neeg laus neurogenesis tuav tus yuam sij rau kev kho cov mob neurodegenerative xws li Alzheimer's disease.
Neuroplasticity yog dab tsi?
Neuroplasticity yog lub peev xwm ntawm lub hlwb hloov. Thaum peb cuam tshuam nrog ib puag ncig, ntau qhov kev hloov pauv ntawm lub cev yuav tshwm sim hauv lub hlwb. Yog li ntawd, peb lub hlwb tsim kev sib txuas tshiab thiab txoj hauv kev thiab hloov raws li lawv. Neuroplasticity suav nrog kev sau ntawm ntau lub hlwb hloov pauv thiab hloov pauv qhov tshwm sim.
Daim duab 02: Neuroplasticity
Muaj ob hom neuroplasticity raws li cov txheej txheem neuroplasticity thiab kev ua haujlwm neuroplasticity. Neurogenesis pab txhawb rau neuroplasticity. Zoo ib yam li neurogenesis, neuroplasticity yog lwm txoj kev kho rau cov kab mob neurodegenerative.
Neuroregeneration yog dab tsi?
Neuroregeneration yog regrowth lossis kho cov paj hlwb. Nws tuaj yeem ua tau los ntawm kev tsim cov neurons tshiab, axons, myelin, synapses thiab glial hlwb. Cov txheej txheem no txawv ntawm lub hauv nruab nrab lub paj hlwb (lub hlwb thiab tus txha caj qaum) thiab lub paj hlwb peripheral. Lub paj hlwb peripheral muaj qhov muaj peev xwm ua tau rau neuroregeneration. Hauv qhov sib piv, feem ntau ntawm cov hlab ntsha hauv nruab nrab tsis tuaj yeem kho tus kheej thiab rov tsim dua tshiab.
Daim duab 03: Nerve Damage
Neuroregeneration tuaj yeem rov qab cuam tshuam kev sib txuas neuronal. Thaum lub sij hawm neuroregeneration, cov axons uas twb muaj lawm yog elongated. Ntxiv mus, sprouting thiab loj hlob ntawm tshiab neurons los ntawm lub soma ntawm neural hlwb, nrog rau remyelination tshwm sim. Kev hloov pauv ntawm cov qia hlwb ib lub tswv yim zoo rau kev tsim kho neuroregeneration.
Dab tsi yog qhov zoo sib xws ntawm Neurogenesis Neuroplasticity thiab Neuroregeneration?
- Neurogenesis, neuroplasticity thiab neuroregeneration yog peb txheej txheem tshwm sim hauv cov ntaub so ntswg.
- Txhua peb txheej txheem pab hauv lub hlwb rov qab los tom qab kev puas tsuaj, tshwj xeeb tshaj yog tom qab mob stroke lossis raug mob.
- Lub tswvyim ntawm neuroregeneration suav nrog neurogenesis thiab neuroplasticity.
Qhov txawv ntawm Neurogenesis Neuroplasticity thiab Neuroregeneration yog dab tsi?
Neurogenesis yog tsim los ntawm cov neurons tshiab los ntawm neural progenitor hlwb hauv lub hlwb thaum neuroplasticity yog lub peev xwm ntawm lub hlwb los hloov nws cov kev ua ub no nyob rau hauv teb rau intrinsic los yog extrinsic stimuli los ntawm reorganizing nws cov qauv, functions, los yog kev sib txuas. Neuroregeneration, ntawm qhov tod tes, yog regrowth lossis kho cov paj hlwb los ntawm kev tsim cov neurons tshiab, axons, synapses, thiab glial hlwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm neurogenesis neuroplasticity thiab neuroregeneration.
Summary – Neurogenesis Neuroplasticity vs Neuroregeneration
Nyob rau hauv kev qhia txog qhov sib txawv ntawm neurogenesis neuroplasticity thiab neuroregeneration, neurogenesis yog tsim cov neurons tshiab los ntawm neural qia thiab progenitor hlwb thaum neuroplasticity yog lub peev xwm ntawm lub hlwb los tsim kev sib txuas tshiab thiab txoj hauv kev thiab hloov li cas nws circuits yog wired thiab neuroregeneration yog regrowth los yog kho cov paj hlwb. Tag nrho cov txheej txheem no tseem ceeb hauv kev kho cov kab mob neurodegenerative.
