Badminton players of varying skill levels viewed normal and point-light video clips of opponents striking the shuttle towards the viewer; their task was to predict in which quadrant of the court the shuttle would land. In a whole-brain fMRI analysis we identified bilateral cortical networks sensitive to the anticipation task relative to control stimuli. This network is more extensive and localised than previously reported. Voxel clusters responding more strongly in experts than novices were associated with all task-sensitive areas, whereas voxels responding more strongly in novices were found outside these areas. Task-sensitive areas for normal and point-light video were very similar, whereas early visual areas responded differentially, indicating the primacy of kinematic information for sport-related anticipation.
不同水平的羽毛球运动员观看了正常和点光视频片段，视频中对手将球击向观看者；他们的任务是预测球会落在球场的哪个象限。在全脑 fMRI 分析中，我们确定了相对于对照刺激对预期任务敏感的双侧皮质网络。与之前报道的相比，这个网络更广泛，更局限。在专家中比新手反应更强的体素簇与所有任务敏感区域相关，而在新手中外周区域反应更强的体素。正常和点光视频的任务敏感区域非常相似，而早期视觉区域的反应不同，这表明运动相关预期中运动信息的首要地位。
