This study investigated neuronal activation differences under two conditions: driving only and distracted driving. Driving and distraction tasks were performed using a Magnetic Resonance (MR)-compatible driving simulator with a driving wheel and pedal. The experiment consisted of three blocks, and each block had both a Rest phase (1 min) and a Driving phase (2 min). During the Rest phase, drivers were instructed to simply look at the stop screen without performing any driving tasks. During the Driving phase, each driver was required to drive at 110 km/h under two conditions: driving only and driving while performing additional distraction tasks. The results show that the precuneus, inferior parietal lobule, supramarginal gyrus, middle frontal gyrus, cuneus, and declive are less activated in distracted driving than in driving only. These regions are responsible for spatial perception, spatial attention, visual processing and motor control. However, the cingulate gyrus and sub-lobar regions (lentiform nucleus and caudate), which are responsible for error monitoring and control of unnecessary movement, show increased activation during distracted driving compared with driving only.
仅驾驶和分心驾驶。驾驶和分心任务是使用带有方向盘和踏板的磁共振（MR）兼容驾驶模拟器进行的。实验由三个区块组成，每个区块都有一个休息阶段（1分钟）和一个驾驶阶段（2分钟）。在休息阶段，驾驶员被指示只需看着停止屏幕，不执行任何驾驶任务。在驾驶阶段，每位驾驶员需要在两种情况下以110公里/小时的速度驾驶：仅驾驶和在执行额外分心任务时驾驶。结果表明，与仅驾驶相比，分心驾驶时楔前叶、顶下小叶、缘上回、额中回、楔叶和小脑山坡的激活程度较低。这些区域负责空间感知、空间注意力、视觉处理和运动控制。然而，负责错误监测和控制不必要运动的扣带回和脑叶下区域（豆状核和尾状核）与仅驾驶相比，在分心驾驶时激活增加。
