abstract
UMLANDO:
Ukuhlolwa kwe-neuroimaging esebenzayo kwizihloko zokulawula okunempilo kubonise ukuthi ukukhetha phakathi kwemiklomelo encane futhi esheshayo uma kuqhathaniswa nemiklomelo emikhulu kodwa elandelwayo ekukhishweni kokuphuza (DD) iqoqa i-cortex yangaphambili kanye ne-latal frontal cortex. Kungenzeka yini ukuthi ukuhlukana komuntu ngamunye ku-morphology ye-gronous frontocortical kuhlotshaniswa nokukhethwa komvuzo osheshayo?
IZINDLELA:
Sixoxisane ne-DD emsebenzini wokuthatha izinqumo ebhrothatori ukuze kube nemibandela eqondile ye-gray frontocortical (GM) ebalwe kusuka kwizithombe zamagnetic resonance ezihlangene ku-29 abadala abadala.
IZIPHUMA:
I-cororsx ye-Dorsolateral ne-inferolateral yangaphambili ye-cortex (iqondiswe njengengxenye yomsindo wobuchopho obuchosayo) ngamunye ohlangene ngokungafani nokukhetha ukuzithokozisa ngokushesha ngesikhathi sokwenza izinqumo, njengoba ilandelwe yi-DD njalo k. Ngakolunye uhlangothi, akukho ukulinganiswa komfutho we-cortex we-cortex noma i-cortex GM ivolumu noma ivolumu yengqondo ye-cerebral (CBV) noma inani elingu-total incracranial (ICV; isilinganiso sokukhula kobuchopho obukhulu) esivumelana kakhulu ne-DD.
IMIBUZO:
Ukuqina kwesaphulelo sezinkokhelo ezibambezelekile kufana ne-lateral lateral frontocortical GM morphology kodwa hhayi ngezinyathelo zobuchopho. Ngaphandle kobufakazi bokungavamile okubonakalayo ekuxhasweni ngokwezinto ezibonakalayo kanye nokuhlalisana kwabantu, izifundo zesikhathi esizayo zingahlola ukuthi i-volume encane ye-frontocortical iyancipha ngokwayo ingummaki we-morphological noma ingozi yokungakwazi ukulibala ukugcwala ekuhluphekeni kwengqondo.
