使用功能磁共振成像研究涉及处理动态视觉运动表征转换的大脑区域。感知运动任务涉及以第一人称和第三人称追逐视角驾驶（或观察）飞机通过模拟的红牛航空竞赛路线。第三人称视角类似于车辆的远程操作。人类远程操作车辆的能力可能源于与模仿相关的神经过程，其中视觉运动转换对于以适合执行的自我中心方式解释行动目标是必要的。在这个第三人称视角的实验中，视觉运动变换根据平面的方向动态变化。据预测，第三人远程飞行（超过第一人）将利用组成“镜像神经元”系统的大脑区域，该系统被认为与执行和观察任务的模仿密切相关。与此预测一致，在左腹侧前运动皮层、右背侧前运动皮层和双侧顶下小叶（镜像神经元系统）的执行和观察任务中，第三人称与第一人称视角的大脑活动存在差异（行为上：第一>第三）。这些区域还表现出在监视（观察）条件下飞行（执行）的更大活动。尽管任务的视觉和运动方面受到控制，但在涉及工具使用、运动感知和身体视角的大脑区域也发现了不同的活动，包括左小脑、颞枕区、枕外侧皮层、内侧颞区和纹外体区域。该实验成功地证明了复杂的感知运动现实世界任务可用于研究视觉运动处理。这种方法（航空脑实验科学 ACES）侧重于直接应用于实验室和现场，这与标准方法形成鲜明对比，在标准方法中，任务和条件被简化为远离日常生活经验的最简单形式。
Brain regions involved with processing dynamic visuomotor representational transformation are investigated using fMRI. The perceptual-motor task involved flying (or observing) a plane through a simulated Red Bull Air Race course in first person and third person chase perspective. The third person perspective is akin to remote operation of a vehicle. The ability for humans to remotely operate vehicles likely has its roots in neural processes related to imitation in which visuomotor transformation is necessary to interpret the action goals in an egocentric manner suitable for execution. In this experiment for 3rd person perspective the visuomotor transformation is dynamically changing in accordance to the orientation of the plane. It was predicted that 3rd person remote flying, over 1st, would utilize brain regions composing the ‘Mirror Neuron’ system that is thought to be intimately involved with imitation for both execution and observation tasks. Consistent with this prediction differential brain activity was present for 3rd person over 1st person perspectives for both execution and observation tasks in left ventral premotor cortex, right dorsal premotor cortex, and inferior parietal lobule bilaterally (Mirror Neuron System) (Behaviorally: 1st>3rd). These regions additionally showed greater activity for flying (execution) over watching (observation) conditions. Even though visual and motor aspects of the tasks were controlled for, differential activity was also found in brain regions involved with tool use, motion perception, and body perspective including left cerebellum, temporo-occipital regions, lateral occipital cortex, medial temporal region, and extrastriate body area. This experiment successfully demonstrates that a complex perceptual motor real-world task can be utilized to investigate visuomotor processing. This approach (Aviation Cerebral Experimental Sciences ACES) focusing on direct application to lab and field is in contrast to standard methodology in which tasks and conditions are reduced to their simplest forms that are remote from daily life experience.
