Tagata suʻesuʻega neuroimaging suʻesuʻega fautua mai le i ai o le tasi autu fesoʻotaʻiga mo le faʻatulagaina faʻatauaina o taui, e aofia ai le striatum ma orbitofrontal cortex. Ae ui i lea, e i ai laʻititi suʻesuʻega i luga o le neural representation o le taua taui faʻamanuiaga o vaʻaia feusuaʻiga faʻamalosi (VSS) ma luga o le matafaioi a nei autu faʻatatau iloiloga i le atinaʻeina o fesoʻotaʻiga amioga faʻafeusuaiga. Lenei, matou te suʻesuʻe pe faʻafefea ona fesoʻotaʻi le neural reactivity i le VSS i mea e manaʻomia e tagata e faʻaaoga ai le magnetic resonance imaging (fMRI). I le taimi o le fMRI scan, e toʻa 72 aliʻi na matamata i ata VSS eseese. Fua faʻatatau i le valence ma feusuaʻiga faʻamalosi na aoina ma faʻaaogaina o parametric modulator i le fMRI auiliiliga. O mataupu na faʻatumuina foi fesili i luga o latou lava faʻailoga o faʻafitauli o ponokalafi faʻafitauli (PPU). Muamua lava, na matou mauaina o le neural reactivity agaʻi i VSS ata i totonu o le tumutumu accumbens, caudate nusipepa ma orbitofrontal cortex sa lelei faʻatasi ma faʻatulagaina taʻitasi o le VSS taʻitasi i mataupu uma. Lona lua, o le malosiaga o le faʻatasiga i le va o neura gaioiga ma feusuaʻiga faʻaosofia feusuaʻiga na mautinoa le faʻafesoʻotaʻi ma ia lava lipotia faʻailoga o le PPU. O le iʻuga muamua o loʻo fautua mai ai se iloiloga saʻo o le VSS e tusa ma mea e manaʻomia e tagata taʻitoʻatasi i itulagi faʻatauaina o taui. Lona lua, faʻamalosia neural eseʻese malosi faʻavae i luga o le fiafia i tagata auai ma sili atu PPU faʻailoga faʻaalia ai le faʻateleina taua o VSS / fiafia i ai talafeagai i nei tagata taʻitasi. O lenei faʻateleina fetusiaʻiga i le va o tagata taʻutaʻua ma neural gaioiga ono faʻafaigofieina PPU atinaʻe e ala i le faʻateleina o le faʻailo o lagona faʻaosofia agavaʻa, ma faʻamalosia ai le faʻaosofia e saili ma tali atu i nei fiafia faʻaosofia.
