More males than females play video games and develop problems with gaming. However, little is known regarding how males and females who game on the Internet may differ with respect to neural responses to gaming cues. Behavioral and functional magnetic resonance imaging (fMRI) data were recorded from 40 female and 68 male Internet gamers. This study included three components including participation in a pre-gaming cue-craving task, 30 min of online gaming and a post-gaming cue-elicited-craving task. Group differences were examined at pre-gaming, post-gaming and post- vs pre-gaming times. Correlations between brain responses and behavioral performance were calculated. : Gaming-related cues elicited higher cravings in male vs female subjects. Prior to gaming, males demonstrated greater activations in the striatum, orbitofrontal cortex (OFC), inferior frontal cortex and bilateral declive. Following gaming, male subjects demonstrated greater activations in the medial frontal gyrus and bilateral middle temporal gyri. In a post-pre comparison, male subjects demonstrated greater thalamic activation than did female subjects. Short-term gaming elicited in males vs females more craving-related activations to gaming cues. These results suggest neural mechanisms for why males may be more vulnerable than females in developing Internet gaming disorder.
更多的男性比女性玩电子游戏并出现游戏问题。然而，对于在互联网上玩游戏的男性和女性在对游戏线索的神经反应方面可能有何不同，人们知之甚少。从 40 名女性和 68 名男性互联网游戏玩家那里记录了行为和功能磁共振成像（fMRI）数据。本研究包括三个部分，包括参与预游戏线索渴求任务、30 分钟的在线游戏和游戏后线索诱发渴求任务。在预游戏、游戏后和游戏后与预游戏时间检查了组间差异。计算了大脑反应与行为表现之间的相关性。：与游戏相关的线索在男性中比女性引起更高的渴望。在游戏之前，男性在纹状体、眶额皮质（OFC）、下额前皮质和双侧下斜肌中表现出更大的激活。在游戏之后，男性受试者在额内侧回和双侧颞中回中表现出更大的激活。在前后比较中，男性受试者的丘脑激活比女性受试者更大。短期游戏在男性中比女性中引起更多与游戏线索相关的渴望激活。这些结果表明了男性比女性更容易患上网络游戏障碍的神经机制。
