MALANGIZO:
Ngakhale kafukufuku waposachedwa wasonyeza bwino ntchito zamagulu abwinobwino mwa achinyamata omwe ali ndi vuto la masewera a intaneti (IGA), ndizochepa zomwe zimadziwika momwe IGA imakhudzira kupindika muubongo wamunthu. Tidagwiritsa ntchito pseudocontinuous arterial spin-labeling (ASL) perfusion functional magnetic resonance imaging (fMRI) kuyeza zovuta za IGA pa kupumula kwa ntchito zaubongo poyerekeza kupumula kwa magazi a muubongo mu achinyamata ndi IGA ndi maphunziro wamba.
ZITSANZO:
Achinyamata khumi ndi asanu omwe ali ndi IGA ndi 18 amafanana ndi achinyamata ovomerezeka omwe adakumana ndi fMRI ya kakhazikitsidwe kazinthu zopumira. Kutulutsa mwachindunji, zojambula zamtundu wa voxel-smart generalar zidapangidwa kuti ziyerekeze kupumula kwa magazi a magazi (ubongo) pakati pa magulu a 2. Correlation idawerengedwa pakati pa mtengo wamtengo wapatali wa CBF m'magulu onse omwe adapulumuka kukonza kwa AlphaSim ndi kuchuluka kwa Chen Internet Addiction Scale (CIAS), Barratt Impulsiveness Scale-11 (BIS-11), kapena maola ogwiritsa ntchito intaneti pa sabata (maola) mu Maphunziro a 15 ndi IGA.
ZOKHUDZA:
Poyerekeza ndi maphunziro olamulira, achinyamata omwe ali ndi IGA adawonetsa kwambiri padziko lonse lapansi CBF kumanzere wotsika pang'ono lobe / fusiform gyrus, lamanzere parahippocampal gyrus / amygdala, lamanzere lamanja lakutsogolo / anterior cingate cortex, lamanzere kumanzere, kumanzere kumanja, kumanja pakati precentral gyrus, lamanzere owonjezera galimoto malo, lamanzere cingate gyrus, ndi kumanja kopondera parietal lobe. CBF Yotsika idapezeka kumanzere kwakanthawi kwakanthawi, kumanzere pakati pa ziwanda, komanso kumata gilusi. Tapa panalibe kulumikizana kwakukulu pakati pa matanthauzo a CBF m'magulu onse omwe adapulumuka kukonza kwa AlphaSim ndi CIAS kapena BIS-11 zambiri kapena maola ogwiritsa ntchito intaneti pa sabata.
MAFUNSO:
Mu phunziroli, tidagwiritsa ntchito ASL Fusionum ya ASL ndipo sitinasinthe ndikupumula kwa CBF kuwonetsa kuti IGA ikusintha kugawa kwa CBF muubongo wachinyamata. Zotsatirazo zimathandizira kuyerekezera kuti IGA ndichizolowezi chomwe chingagawane zomwe zimayambitsa matenda amtunduwu ndi zovuta zina.
