在大脑中，左脑和右脑的注意力机制是不同的。驾驶时的大脑活动也可能随着水平道路的不同而不同（向左或向右弯曲），但对此知之甚少。我们使用大型驾驶模拟器和功能性近红外光谱（fNIRS）进行了一项实验，发现驾驶员在左右弯道行驶时大脑活动不同。参与者是15名健康的成年人。我们创建了一个模拟高速公路的课程，包括直线驾驶和平缓的左右弯道，并在驾驶条件下对参与者进行监测，在驾驶条件下，他们以100公里/小时的恒定速度驾驶，在非驾驶条件下，他们只是看屏幕（视觉任务）。在前额叶皮质、运动前皮质、初级运动皮质和顶叶皮质等48个通道监测血红蛋白浓度的变化。通过脱氧血红蛋白变化和含氧血红蛋白变化的正交向量，计算反映神经活动的脑氧交换变化，并对左右曲线截面的结果值进行统计比较。在驾驶条件下，脑氧交换在右转弯时没有明显高于左转弯时的增加（p < 0.05），但在左转弯时，脑氧交换在右侧运动前皮层、右侧额叶视野和双侧前额叶皮层显著增加（p < 0.05）。在非驾驶条件下，左侧弯道只有右侧额眼区增加显著（p < 0.05）。因此，左侧弯道驾驶需要更多的大脑活动在多个部位，这表明左侧弯道驾驶可能比右侧弯道驾驶需要更多的视觉注意力。在驾驶和非驾驶条件下，右额叶视野都被激活。
In the brain, the mechanisms of attention to the left and the right are known to be different. It is possible that brain activity when driving also differs with different horizontal road alignments (left or right curves), but little is known about this. We found driver brain activity to be different when driving on left and right curves, in an experiment using a large-scale driving simulator and functional near-infrared spectroscopy (fNIRS). The participants were fifteen healthy adults. We created a course simulating an expressway, comprising straight line driving and gentle left and right curves, and monitored the participants under driving conditions, in which they drove at a constant speed of 100 km/h, and under non-driving conditions, in which they simply watched the screen (visual task). Changes in hemoglobin concentrations were monitored at 48 channels including the prefrontal cortex, the premotor cortex, the primary motor cortex and the parietal cortex. From orthogonal vectors of changes in deoxyhemoglobin and changes in oxyhemoglobin, we calculated changes in cerebral oxygen exchange, reflecting neural activity, and statistically compared the resulting values from the right and left curve sections. Under driving conditions, there were no sites where cerebral oxygen exchange increased significantly more during right curves than during left curves (p > 0.05), but cerebral oxygen exchange increased significantly more during left curves (p < 0.05) in the right premotor cortex, the right frontal eye field and the bilateral prefrontal cortex. Under non-driving conditions, increases were significantly greater during left curves (p < 0.05) only in the right frontal eye field. Left curve driving was thus found to require more brain activity at multiple sites, suggesting that left curve driving may require more visual attention than right curve driving. The right frontal eye field was activated under both driving and non-driving conditions.
