We studied 12 healthy subjects with fMRI while they performed a driving simulation task. In the active condition they steered the car themselves (driving), in the passive condition a person from outside the scanner was steering the car (passive driving). Common activations in both conditions were found in occipital and parietal regions bilaterally. Activity specifically associated with driving was found only in the sensorimotor cortex and the cerebellum. Compared to passive driving, activity during driving was reduced in numerous brain regions including MT/MST. It is concluded that simulated driving requires mainly perceptual-motor integration and that the limited cognitive capacity model of driving has to be revised.
我们对12名健康受试者进行功能磁共振成像（fMRI）研究，让他们执行驾驶模拟任务。在主动条件下，他们自己驾驶汽车（驾驶状态），在被动条件下，扫描仪外的一名人员驾驶汽车（被动驾驶状态）。在两种条件下，双侧枕叶和顶叶区域均发现了共同激活。仅在感觉运动皮层和小脑中发现了与驾驶特异性相关的活动。与被动驾驶相比，驾驶过程中包括MT/MST在内的许多脑区的活动减少。得出的结论是，模拟驾驶主要需要感知-运动整合，并且驾驶的有限认知能力模型必须修正。
