考虑到一个决定，需要不到半秒的时间来评估传入球场的特征和产生运动响应，击球可能需要独特的感知-动作耦合来实现高性能。我们设计了一个快速知觉决策实验，模拟为一个去/不去的任务，但量身定制，以反映一个真实的场景所面临的棒球击球手。对于专家组（一级棒球运动员）和新手组（非运动员），我们在他们执行任务时记录了脑电图（EEG）。我们分析了诱发脑电图单次试验的变异性，关联负变（CNV），和前刺激阿尔法功率与专家与新手组。我们发现了两组之间抑制过程差异的有力证据，特别是辅助运动区（SMA）的差异活动，表明专家（棒球运动员）组的抑制控制增强。我们还发现了梭状回（FG）和眶回的选择性活动的专家组，这表明增强感知-动作耦合的棒球运动员，区分他们从匹配的控制。总之，我们的研究结果表明，决策形成的脑电图相关可以用来识别高性能运动员的神经标记。
Given a decision that requires less than half a second for evaluating the characteristics of the incoming pitch and generating a motor response, hitting a baseball potentially requires unique perception-action coupling to achieve high performance. We designed a rapid perceptual decision making experiment modeled as a Go/No-Go task, yet tailored to reflect a real scenario confronted by a baseball hitter. For groups of experts (Division I baseball players) and novices (non-players) we recorded electroencephalography (EEG) while they performed the task. We analyzed evoked EEG single-trial variability, contingent negative variation (CNV), and pre-stimulus alpha power with respect to the expert vs. novice groups. We found strong evidence for differences in inhibitory processes between the two groups, specifically differential activity in supplementary motor areas (SMA), indicative of enhanced inhibitory control in the expert (baseball player) group. We also found selective activity in the fusiform gyrus (FG) and orbital gyrus in the expert group, suggesting an enhanced perception-action coupling in baseball players that differentiates them from matched controls. In sum, our results show that EEG correlates of decision formation can be used to identify neural markers of high-performance athletes.
