The present functional magnetic resonance imaging study examined the neural response to familiar and unfamiliar, sport and non-sport environmental sounds in expert and novice athletes. Results revealed differential neural responses dependent on sports expertise. Experts had greater neural activation than novices in focal sensorimotor areas such as the supplementary motor area, and pre- and postcentral gyri. Novices showed greater activation than experts in widespread areas involved in perception (i.e. supramarginal, middle occipital, and calcarine gyri; precuneus; inferior and superior parietal lobules), and motor planning and processing (i.e. inferior frontal, middle frontal, and middle temporal gyri). These between-group neural differences also appeared as an expertise effect within specific conditions. Experts showed greater activation than novices during the sport familiar condition in regions responsible for auditory and motor planning, including the inferior frontal gyrus and the parietal operculum. Novices only showed greater activation than experts in the supramarginal gyrus and pons during the non-sport unfamiliar condition, and in the middle frontal gyrus during the sport unfamiliar condition. These results are consistent with the view that expert athletes are attuned to only the most familiar, highly relevant sounds and tune out unfamiliar, irrelevant sounds. Furthermore, these findings that athletes show activation in areas known to be involved in action planning when passively listening to sounds suggests that auditory perception of action can lead to the re-instantiation of neural areas involved in producing these actions, especially if someone has expertise performing the actions.
本功能磁共振成像研究考察了专家级和新手级运动员对熟悉和不熟悉的、运动和非运动环境声音的神经反应。结果显示,神经反应因运动专业水平而异。在诸如辅助运动区以及中央前回和中央后回等焦点感觉运动区域,专家级运动员比新手级运动员有更强的神经激活。新手级运动员在涉及感知的广泛区域(即缘上回、枕中回和距状回;楔前叶;顶叶上下小叶)以及运动规划和处理区域(即额下回、额中回和颞中回)比专家级运动员表现出更强的激活。这些组间神经差异在特定条件下也表现为专业水平效应。在负责听觉和运动规划的区域,包括额下回和顶叶岛盖,专家级运动员在运动熟悉条件下比新手级运动员表现出更强的激活。新手级运动员仅在非运动不熟悉条件下的缘上回和脑桥以及运动不熟悉条件下的额中回比专家级运动员表现出更强的激活。这些结果与以下观点一致:专家级运动员只对最熟悉、高度相关的声音有反应,而忽略不熟悉、不相关的声音。此外,这些研究结果表明,运动员在被动听声音时,在已知参与动作规划的区域出现激活,这表明对动作的听觉感知可以导致参与产生这些动作的神经区域重新激活,特别是如果某人具有执行这些动作的专业技能。
