【摘要】：为了探讨乒乓球运动员在经验相关图形识别过程中的大脑皮层激活变化,以抽象的经验相关图形为刺激材料,运用64导脑电测试系统记录了14名乒乓球运动员和14名非运动员在简单反应和辨别反应任务中的脑电数据,分析低频α(8~10Hz)和高频α(10~12Hz)事件相关去同步化/同步化(ERD/ERS)指标。结果发现:在简单反应任务中,运动员与非运动员的αERD/ERS无差异;在辨别反应任务中,运动员额区(P=0.006)和中央区(P=0.004)的低频αERD及额区(P=0.007)和中央区(P=0.026)的高频αERD高于非运动员,顶区(P=0.014)和枕区(P=0.035)的高频αERD低于非运动员。研究结果表明,运动员在经验相关图形识别中的神经效率受到任务要求和脑区的调节,其大脑皮层激活并非严格遵循"神经效率"策略,而是具有专家大脑皮层加工的选择性激活特性。
[Abstract]:In order to explore the cortical activation changes of table tennis players in the process of experiential correlation pattern recognition, abstract experiential correlation patterns were used as stimulant materials. The EEG data of 14 table tennis players and 14 non-athletes in the task of simple reaction and discrimination reaction were recorded with the 64 lead EEG test system. The indexes of de-synchronizing / synchronizing ERD / ERS related to low-frequency 伪 -8 ~ (10 ~ (10) Hz) and high-frequency 伪 ~ (10 ~ (10) ~ (12) Hz) events were analyzed. The results showed that there was no difference in 伪 ERD/ERS between athletes and non-athletes in simple reaction tasks, but in identifying reaction tasks, there was no difference between athletes and non-athletes. The high frequency 伪 ERD of the frontal area (P0. 006) and the central area (P0. 004)) and the frontal area (P0. 007) and the central area (P0. 026)) were higher than that of the non-athletes, and the high frequency 伪 ERD of the top area (P0. 014) and the occipital area (P0. 035)) were lower than that of the non-athletes. The neural efficiency of athletes in experience-related pattern recognition is regulated by task requirements and brain regions. The activation of cerebral cortex is not strictly in accordance with the "neural efficiency" strategy, but has the characteristics of selective activation of expert cerebral cortex processing.
