Abstract
UMGQUBO:
Uvavanyo olusebenzayo lwe-neuroimaging kwizifundo zolawulo olusempilweni lubonise ukuba ukukhetha phakathi kwemivuzo emincinci kunye nekhawulezileyo ngokuchasene nemivuzo emikhulu kodwa erhoxisiweyo ekubambezelekeni kwesaphulelo (DD) imisebenzi ifumana i-mesofrontal kunye ne-lateral frontal cortex. Ngaba iyantlukwano yomntu ngamnye kwi-frontocortical grey morphology inokunxulumana nokukhetha umvuzo okhawulezileyo?
IINDLELA:
Siye sanxulumanisa iDD kumsebenzi wokwenza izigqibo kwilabhoratri kwimiqulu engwevu engaphambili (GM) ebalwa ukusuka kwimifanekiso yemagnethi ecandiweyo kubantu abadala abangama-29 abasempilweni.
IINKCUKACHA:
I-Dorsolateral kunye ne-inferolateral frontal cortex GM imithamo (elungiswe njengenxalenye yomthamo wobuchopho obupheleleyo) nganye ilungelelaniswe ngokungafaniyo nokukhetha ukwaneliseka kwangoko ngexesha lokuthathwa kwezigqibo., njengoko kuboniswe nguDD rhoqo k. Ngakolunye uhlangothi, akukho mthamo we-orbitofrontal okanye i-mesofrontal cortex ye-GM okanye umthamo wobuchopho be-cerebral (CBV) okanye umthamo opheleleyo we-intracranial (ICV; umlinganiselo wokukhula kobuchopho okukhulu) okuhambelana kakhulu nobungqongqo be-DD.
IMISEBENZI:
Ubungqongqo besaphulelo semivuzo elibazisekayo bunxibelelene ne-lateral frontocortical GM morphology kodwa hayi ngemilinganiselo yobuchopho epheleleyo.. Ngobungqina bokungaqhelekanga kokuxhomekeka kwiziyobisi kunye nentlalontle, amaphononongo exesha elizayo anokuhlola ukuba ingaba umthamo oncitshisiweyo we-frontocortical ngokwayo sisimakishi se-morphological okanye umngcipheko wokungakwazi ukulibazisa ukwaneliseka kwiziphazamiso zengqondo.
