IMIBUZO: Abantu abakhuluphele banokungahambi kahle kobuchopho ezindaweni ezihlotshaniswa nokunambitheka, ukuzithiba, nomvuzo. Ezinye zezinguquko zifaka ukwehliswa kwendaba empunga kuma-lobes angaphambili (ukungazenzisi). Kungenzeka ukuthi ukudla ngokweqile kudale lezi zinguquko, njengoba izifundo zakamuva ziqinisekisile izinguquko zobuchopho kusuka ekudleni ngokweqile. Uma ukugqugquzela ngokweqile ukudla kubangela ushintsho lobuchopho, kungenzeka kanjani ukuthi ukusetshenziswa ngokweqile kwe-porn akukwazi?

abstract
Ukukhuluphala kuhambisana nokulimala kwezicubu eziningana. Ukukhuluphala ngokweqile kuyingozi engozini yesifo i-Alzheimer's kanye nezinye izifo ze-neurodegenerative. Ukuthi ukungahleleki okuhlelekile okuhlobene namafutha omzimba okweqile kungenzeka futhi ebuchosheni akwaziwa. Sifuna ukuthola ukuthi amafutha omzimba amaningi ngokweqile ahlotshaniswa kanjani nokushintshwa kwesifunda esakhiweni sobuchopho kusetshenziswa i-voxel-based morphometry (VBM), inqubo engachemile yobuchopho obususelwa kusikena sencazelo ephezulu ye-3D magnetic resonance imaging (MRI) eyenziwe yaba yinto ejwayelekile isikhala esijwayelekile futhi sivumela ukuhlolwa kwenhloso yokwehluka kwe-neuroanatomical kulo lonke ubuchopho. Sifunde ama-24 okhuluphele (11 owesilisa, 13 wesifazane; age: 32 +/- 8 years; body mass index [BMI]: 39.4 +/- 4.7 kg / m2) and 36 lean (25 male, 11 female; mean age: 33 +/- 9 iminyaka; I-BMI: 22.7 +/- 2.2 kg / m2) abaseCaucasus abangashukela besifo sikashukela. Uma kuqhathaniswa neqembu lezifundo ezincikile, iqembu labantu abakhuluphele lalinesisindo esiphansi kakhulu sezimpunga ku-gyrus yangaphakathi nendawo, i-operculum engaphambili, i-putamen, ne-gyrus engaphambili maphakathi (P <0.01 ngemuva kokulungiswa kocansi, ubudala, ukunikezwa, umhlaba wonke ukuminyana kwezicubu, nokuqhathanisa okuningi). I-BMI yayihlotshaniswa kabi nobuningi be-GM ye-gyrus yangakwesokunxele esembindini ezifundweni ezikhuluphele kodwa ezingancikile. Lolu cwaningo lubonisa ukuhlukahluka kobuchopho obuhle ekukhusheni komuntu ezindaweni eziningana zobuchopho ngaphambili ezihilelekile ekulawuleni ukunambitheka, ukuvuza nokuziphatha kokulawula. Lezi zinguquko zingase zandulele ukukhuluphala, ezimelela uphawu lwe-neural lwe-propulsion ye-neural yokukhula kwesisindo, noma zenzeke ngenxa yokukhuluphala, okubonisa ukuthi ubuchopho buyathinteka kakhulu.
