Tali atu i le Neural i taui eseese ma manatu faaalia i le mafaufau o mea taulasea i luga o le Initaneti ua maua i foliga vaaia o le magnet resonance imaging (2014)

AIM:

This study aimed to examine differences in brain activation for various types of reward and feedback in adolescent Internet addicts (AIA) and normal adolescents (NA) using functional magnetic resonance imaging (fMRI).

METHODS:

AIA (n = 15) and NA (n = 15) underwent fMRI while performing easy tasks for which performance feedback (PF), social reward (SR) (such as compliments), or monetary reward (MR) was given. Using the no reward (NR) condition, three types of contrasts (PF-NR, SR-NR, and MR-NR) were analyzed.

TULAFONO:

In NA, we observed activation in the reward-related subcortical system, self-related brain region, and other brain areas for the three contrasts, but these brain areas showed almost no activation in AIA. Instead, AIA showed significant activation in the dorsolateral prefrontal cortex for the PF-NR contrast and the negative correlation was found between the level of activation in the left superior temporal gyrus (BA 22) and the duration of Internet game use per day in AIA.

FAAIUGA:

O nei suʻesuʻega ua fautua mai ai o le AIA o loʻo faʻaalia le faʻaitiitia o le maualuga o le faia o faiʻai i le tagata lava ia ma faʻaititia ai le tauleleia o le mafaufau tusa lava po o le a le ituaiga taui ma faʻamatalaga. O le AIA atonu e naʻo le nofouta i le siakiina o mea sese e tusa lava po oa ni lagona lelei, e pei o le lagona faamalieina pe ausia.
