Synaptic pruning yog ntuj tsim txheej txheem tias tshwm sim hauv lub hlwb nruab nrab ntawm menyuam yaus thiab neeg laus. Lub sijhawm synaptic pruning , cov lub hlwb tshem tawm cov synapses ntxiv. Synapses yog lub hlwb cov qauv uas tso cai rau cov neurons xa cov hluav taws xob lossis cov pa hluav taws xob mus rau lwm lub neuron.
Ib yam li ntawd, cov txheej txheem pruning hauv lub hlwb yog dab tsi?
Txawm hais tias qhov tseeb nws muaj ntau qhov sib txawv nrog kev tswj hwm kev paub txog kev loj hlob ntawm menyuam yaus, txiav xav tias yog a txheej txheem tshem tawm cov neurons uas tej zaum yuav puas los yog degraded nyob rau hauv thiaj li yuav ntxiv txhim kho lub "networking" muaj peev xwm ntawm ib cheeb tsam ntawm lub hlwb.
Kuj Paub, yuav ua li cas thaum lub sij hawm lub hlwb kev loj hlob? Cov Lub Hlwb Thaum Kev Txhim Kho Lub paj hlwb tsim los ntawm cov ntaub so ntswg embryonic hu ua ectoderm. Lub rostral (pem hauv ntej) ib feem ntawm cov hlab ntsha neural mus rau txhim kho rau hauv lub hlwb thiab tus so ntawm lub neural raj tsim mus rau hauv tus txha caj qaum. Neural crest cells dhau los ua lub paj hlwb peripheral.
Hauv qhov no, txheej txheem pruning yog dab tsi?
Cov txheej txheem txiav . Pruning txheej txheem hais txog qhov tshwm sim ib txwm muaj txheej txheem uas hloov pauv thiab txo tus naj npawb ntawm neurons, synapses thiab axons uas muaj nyob hauv lub hlwb thiab lub paj hlwb.
Vim li cas pruning tseem ceeb rau kev txhim kho lub hlwb?
Pruning yog txheej txheem uas yog ntau dua tseem ceeb dua ib zaug ntseeg. Pruning yog ib feem tseem ceeb ntawm kev loj hlob ntawm lub paj hlwb vim nws tshem tawm cov kev sib txuas uas tsis siv ntau zaus txaus. Kev txiav muab chav rau feem ntau tseem ceeb networks ntawm kev sib txuas kom loj hlob thiab nthuav, ua rau cov lub hlwb ua tau zoo dua
