Zoo li ntau tus tsiaj, qwj kev hlub qab zib thiab feem ntau pib noj nws sai li sai tau thaum lawv pom. Tab sis ua tsaug rau qhov tshwj xeeb "kev ntxub ntxaug", lawv tuaj yeem tsis lees nws, txawm tias tshaib plab. Qhov no pom ib pab ntawm biologist los ntawm Sussek University hauv UK. Cov kws tshawb fawb muab cov qwj qab zib, thiab tom qab ntawd lambly khob ntawm lub taub hau thaum tus tsiaj nce mus rau nws. Nws ua rau lawv zam tsis txhob delicacy. Cov ntsiab lus ntawm kev sim yog luam tawm nyob rau hauv phau ceev xwm txheej tam sim no biology.
Tom qab kev ntsuam xyuas, cov kws tshawb nrhiav tshawb xyuas tias cov tsiaj ua kom cov khoom qab zib. Lawv pom ib lub tshuab hluav taws xob neural uas hloov pauv cov tshuaj tiv thaiv qwj ib txwm muaj nyob rau thaj chaw.
Dr. Dildiko Kenenes, tus sau, tau piav qhia tias muaj neurons hauv lub paj qwj, cov khoom noj uas tsis zoo. Qhov no ua kom pom tseeb tias tus tsiaj yuav tsis noj txhua yam hauv nws txoj kev. Tab sis thaum qwj pom qab zib, kev ua haujlwm ntawm cov neuron no yuav qeeb. Yog li mollusk pom txoj hauv kev kom muaj kev ua kom zoo. Tom qab kev cob qhia, cov txiaj ntsig hloov: Neurons zoo siab, thiab tsis muaj kev tsim txom - yog li cov tsiaj yog unsubscribed los ntawm qab zib.
Thaum cov kws tshawb nrhiav pom tias muaj cov tshuaj tiv thaiv zoo li no, muaj qwj dua es tsis txhob muaj piam thaj ib daim ntawm lub dib. Tus mollusks calmer fir nws - nws tau muab tawm tias Neural "hloov" ua haujlwm tsuas yog ntawm qhov pom ntawm cov khoom uas cov qwj tau kawm kom tsis lees paub. Tsis tas li ntawd, thaum neurons - "hloov pauv" raug tshem tawm ntawm lub hlwb ntawm cov qwj, cov tsiaj pib muaj qab zib dua.
George kemsees, ib tug tswv cuab ntawm pab neeg tshawb fawb, hais tias lub qwj yog tus qauv theem ntawm tib neeg lub hlwb. "Qhov cuam tshuam ntawm kev inhibitory neuron, uas suppresses cov khoom siv pob txha los ntawm tus qwj, ceeb toom li cas cov cortical tes hauj lwm yog nyob rau hauv inhibittia tswj nyob rau hauv tib neeg lub hlwb. Nws yog ib qho tsim nyog kom tsis txhob "kev ua kom zoo dua qub, uas tuaj yeem ua rau muaj kev sib tw thiab kev rog," piav qhia tus kws tshawb fawb.
Qhov ntawd yog, los ntawm kev sib tw, kev paub tsis zoo nrog cov khoom noj ua rau qhov tseeb tias peb tsis muaj peev xwm zom lub tswv yim los noj ib lub tais tshwj xeeb. "Qee yam Neurons pawg hloov lawv cov haujlwm nyob rau hauv raws li lub koom haum tsis zoo ntawm qee yam zaub mov," biologist summarized.
