私達はインターネット障害の大学生において神経物質と制御欠如との関係性を調査している．ゲーム娯楽時の
反応抑制機能が不足することによってインターネット利用能力の欠如が起こると仮定した．インターネット障害
の 11 人の被験者はゲーム状況下である場合とない場合の 2 条件において fMRI 内で GO/NOGO 課題を行った．
ゲーム画面が個人が課題を行う背景にある見られる場合，インターネット障害グループは命令エラーを起こした．
統制ができるグループは IGD グループと比較してゲーム環境下において DLPFC と上頭頂小葉がより活性した．
さらにこれらの部位の脳活動は IGD グループ間で反応抑制のパフォーマンスと反対の関係性を示した．この結果
から反応抑制機能は IGD グループ間でゲーム娯楽下において正常に機能していないことや，IGD の被験者たちは
ゲーム環境下において反応抑制のための注意の配分や認知制御を保つために DLPFC や上頭頂小葉を活動させる
ことができなかったことが示唆される．このメカニズムは IGD が関わるあらゆる場面において取り入れられるべ
きである．
