Kev hloov pauv hloov pauv ntawm cov ntaub ntawv yog txheej txheem tseem ceeb hauv tib neeg lub hlwb. Thaum ib qho kev pom pom tshwm sim eccentrically nyob rau hauv ib qho kev pom-hemifield, nws yuav xub qhib lub contralateral hemisphere tab sis kuj yog lub ipsilateral ib tug me ntsis ncua vim lub interhemispheric hloov.
Dab tsi yog interhemispheric?
1: dag lossis tshwm sim ntawm lub paj hlwb hemispheres ib qho kev sib txuas lus sib txuas ntawm subdural hematoma interhemispheric. 2: ncua lossis tshwm sim ntawm lub ntiaj teb hemispheres - saib hemisphere kev nkag siab 1b nce kev lag luam interhemispheric interhemispheric carbon dioxide pauv.
Cov ntaub ntawv pauv ntawm hemispheres li cas?
Lub corpus callosum yog qhov loj tshaj plaws fiber ntau hauv tib neeg lub hlwb. Nws txuas ob lub hemispheres los ntawm ntau tshaj 200 lab fibers thiab tso cai rau kev hloov pauv ntawm cov ntaub ntawv (Aboitiz li al., 1992).
hom ntaub ntawv twg tuaj yeem xa mus hla hemispheres yam tsis muaj corpus callosum?
Yog tsis muaj lub cev tsis muaj zog, ib tus neeg nkag tsis tau cov lus qhia nyob rau sab laug hemisphere tsuav yog cov khoom tseem nyob ntawm sab laug tes.
Puas yog corpus a callosum?
Lub cev nqaij daim tawv yog ib pob loj ntawm ntau dua 200 lab myelinated paj fibers uas txuas ob lub hlwb hemispheres, tso cai kev sib txuas lus ntawm txoj cai thiabsab laug ntawm lub hlwb. Qhov txawv txav hauv lub cev corpus callosum tau raug txheeb xyuas hauv cov menyuam yaus raug mob.
Pom zoo:
Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
