Kev ceeb toom tsis yog hais txog tej yam uas peb tsom ntsoov rau - nws tseem txhawj txog txhua yam uas peb tswj hwm. Peb paub hais tias qhov kev xav yog ob qho tib si xaiv thiab tsuas yog siv raws li muaj peev xwm xwb, tab sis pes tsawg zaus peb yuav rho tawm cov ntaub ntawv tsis tseem ceeb thiab ua kom pom qhov teeb meem ntawm peb paub txog tej yam tseem ceeb?
Ntau qhov theories ntawm kev mloog zoo siab rau qhov peb ua li cas peb lub siab tab sis tsis ua raws nraim li cas peb tswj tsis tau tag nrho cov stimuli nyob ib puag ncig peb sib tw rau kev pab cuam.
Ob peb cov kev tshawb fawb tsis ntev los no tau tsom rau lub paj hlwb ntawm txoj kev taug qab no, muab qee lub teeb rau ntawm cov txheej txheem uas ua tau kom muaj kev cuam tshuam zoo li cas peb yuav tsum tsis txhob cuam tshuam.
Nco ntsoov ntawm Neural Theem
Ib txoj kev tshawb nrhiav los ntawm cov neeg tshawb fawb hauv University of Newcastle xyoo 2013 tau qhia tias txoj kev uas cov neurons teb rau sab nraud stimuli impacts muaj peev xwm.
Tus kws sau ntawv Alex Thiele piav qhia:
"Thaum koj sib txuas lus nrog lwm tus, koj tuaj yeem ua rau koj tus kheej hnov zoo dua los ntawm kev hais lus nrov lossis hais tau lus meej ntxiv." Neurons zoo li ua tej yam zoo li thaum peb hmov tshua txog, Lawv xa lawv cov lus ntau dua rau lawv cov neeg koom tes, uas sib piv cov lus nrov "Tiam sis qhov tseem ceeb dua ntais, lawv kuj ua rau lawv txoj kev ntseeg zoo dua, uas piv rau kev hais lus kom meej."
Syncing hlwb Regions
Cov neeg tshawb nrhiav los ntawm Washington University School of Medicine hauv St. Louis pom tau hais tias lub paj hlwb zoo li muaj peev xwm synchronizing ua si hauv thaj tsam ntawm lub hlwb , cia ib tug neeg mloog zoo rau ib txoj hauj lwm.
Cov neeg tshawb xyuas nyiam ua tus txheej txheem siv cov khoos kas ntsej muag - ntsej muag ntawm lub hlwb zoo li "tune rau tib zaus" kom tsim tau ib txoj kab ntawm kev sib txuas lus.
"Peb xav tias lub hlwb tsis yog tsuas yog muab thaj chaw uas pab txhawb rau kev ceeb toom, tiam sis tseem ua rau kom cov cheeb tsam tau qhib kab kev sib txuas lus," explained researcher Amy Daitch.
Txoj kev tshawb no muab kev koom tes saib lub hlwb ua si ntawm cov neeg tuaj koom lawv raws li kev pom lub hom phiaj. Cov neeg koom tau hais kom ntes lub hom phiaj ntawm qhov screen tsis tau tsiv lawv lub qhov muag thiab tom qab ntawd nias lub khawm los qhia tias lawv tau pom lub hom phiaj.
Cov kws tshawb fawb pom muaj yog tias cov neeg tuaj koom lawv hais txog lawv lub hom phiaj, cov cheeb tsam ntawm lub paj hlwb tseem ceeb rau kev ua zoo mloog lawv cov excitability mus kom cov kev sib raug zoo sib npaug. Cov cheeb tsam tsis txuam nrog kev mloog tsis pom zoo xws li cov kev hloov hauv excitability.
Cov sau phau ntawv xav hais tias thaum cov chaw ntawm lub hlwb cuam tshuam rau txoj kev paub txog kev tsim txiaj yog nyob rau theem siab ntawm excitability, cov neeg muaj feem ntau yuav pom ib qho stimulus. Sib piv, thaum excitability qib qis nyob rau hauv cov cheeb tsam no, yuav ua rau lub teeb liab raug kuaj tau ntau dua.
Lub hlwb lub hlwb kev tiv thaiv
Lwm txoj kev tshawb kawm tsis ntev los no qhia tias lub paj hlwb yeej muaj peev xwm txhawb nqa qee qhov cim tseg kom thiaj li tsis txhob cuam tshuam. Cov neeg tshawb xyuas ntseeg tau tias peb lub peev xwm los tsom mus rau ib qho khoom nyob rau hauv ib feem ntawm qhov kev ua tib zoo saib.
"Peb qhov kev tshwm sim qhia meej tias qhov no tsuas yog ib feem ntawm qhov kev ua zauv thiab qhov kev tua hluav taws ntawm cov khoom tsis sib haum yog lwm qhov tseem ceeb," piav qhia thawj coj John Gaspar.
Cov sau phau ntawv kuj hais tias qhov kev tshawb nrhiav txog kev tiv thaiv kev tiv thaiv no yuav muaj kev cuam tshuam rau kev puas siab ntsws ntsig txog kev mob hlwb, nrog rau cov ADHD. Tsis tas li sim ua kom yooj yim dua, cov uas muaj kev sib tham yuav muaj txiaj ntsim los ntawm kev ua haujlwm nrawm rau.
Vim Li Cas Cov Txheej Txheem No?
Yog vim li cas nws thiaj li tseem ceeb kom to taub txog qhov kev tshwm sim tom qab ntawd? Vim tias peb nyob hauv lub ntiaj teb kev cuam tshuam. Thaum twg los xij, ntau txhiab yam yuav tsum sib tw rau peb txoj kev xav thiab peb lub peev xwm los mus saib cov kev xav thiab qhov tseem ceeb ntawm qhov tseem ceeb - yog qhov tseem ceeb uas tej zaum yuav yog qhov txawv ntawm lub neej thiab kev tuag.
Thaum koj tsav tsheb los ntawm kev tsheb khiav hauv npav, koj lub peev xwm los tsom mus rau txoj kev thiab lwm cov tsav tsheb thaum koj tsis quav ntsej (lub xov tooj cua, koj lub xov tooj ntawm tes, qhov kev sib tham ntawm ib tus neeg nrog caij hauv koj lub tsheb) tuaj yeem txhais tau tias qhov txawv ntawm qhov mus txog koj lub hom phiaj kev nyab xeeb lossis nkag mus rau hauv kev sib tsoo tsheb.
Raws li kev tshawb fawb John McDonald piav tias, "Distraction yog qhov ua rau kev raug mob thiab kev tuag hauv kev tsav tsheb thiab lwm qhov chaw siab loj. kev siv zog, thiab qee zaus tib neeg tsis tuaj yeem ua qhov ntawd. "
Cov kev tshawb fawb tshiab txog tias lub hlwb tuav cov kev cuam tshuam thiab tsom ntsoov cov tswv yim rau kev ua li cas txoj haujlwm no thiab muab cov kws tshawb fawb thiab cov kws kho mob tshiab coj los daws cov teeb meem ntawm kev xav.
