Spine plasticity cuam tshuam rau kev txhawb siab, kev kawm, thiab kev nco. Tshwj xeeb, kev nco mus ntev yog mediated nyob rau hauv ib feem los ntawm kev loj hlob ntawm cov tshiab dendritic spines (los yog qhov loj ntawm cov pob txha uas twb muaj lawm) los txhawb ib txoj hauv kev neural.
Neurons sprout dendrites?
Qhov no txawv txav dendritic sprouting restores auditory function rau cov neuron. Yog li, nws tau pom tias lub dendritic zoo ntawm tus txheeb ze Int, nrog rau nws cov kev sib txuas ntawm cov synaptic, tau hloov pauv raws li qhov tshwm sim ntawm kev hnov lus tsis zoo.
Neurons puas muaj dendritic outgrowths?
Neurons yog cov hlwb muaj zog heev nrog cov subcellular sib txawv, suav nrog ib qho lossis ntau yam txheej txheem dendritictshwm sim los ntawm lub cev ntawm tes, thiab ib qho, txuas ntxiv axon.
Puas dendritic spines hloov tau?
Kev hloov pauv hauv dendritic spine morphology (loj lossis shrinkage) thiab / lossis txha nraub qaum (nce lossis txo) tau pom tias tshwm sim nrog synaptic hloov kho, thiab tau thov kom pab. tsis tu ncua, hloov mus sij hawm ntev ntawm synapses.
Can synapses tsim ntawm spines?
Feem ntau cov synapses yog tsim ntawm axonal bouton thiab dendritic spine, uas yog tshwj xeeb protrusion los ntawm dendritic membrane. Dendritic spines tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, txawv heev nyob rau hauv lub hlwb, hom cell, thiab tsiaj hom (Ghani li al., 2017).
