运动中行为失常的脑电特征分析

Analysis of EEG characteristics of performance disorders during movement

目的通过脑电(electroencephalogram,EEG)特征分析运动中人行为失常的神经心理机制。方法采用荷兰ANT公司研制的ANT Neuro eego mylab 64导脑电监测系统,测试1名攀岩国家队运动员攀爬过程中的脑电。比较运动员行为正常与失误、失误前与失误后的脑电特征和脑地形图,探析导致行为失常的脑活动因素。结果行为失常时大脑右侧前额叶、额叶,左大脑中前部、后部突然出现大面积电流活动加强和电压变高,而视觉空间联合皮层则无明显电流活动。结论人们运动中行为失常与大脑突然屏蔽感知觉和产生较多与行为策略相关的认知活动有关,如果人的能力、体力和准备不充分,就会破坏正常的“神经-行为”联动机制,导致动作紊乱。

Objective To analyze the neuropsychological mechanism of human behavior disorder during movement by electroencephalogram(EEG)characteristics.Methods An ANT Neuro eego mylab 64-channel EEG monitoring system was used to test the EEG of a rock climbing national team athlete during climbing.Compared the EEG characteristics and brain maps of athletes’normal behavior and mistakes,before and after mistakes,and explored the brain activity factors that lead to behavioral disorders.Results Before the mistake,the right prefrontal lobe,the frontal lobe,the middle and front part of the left brain and the back part of the athlete’s brain showed a large area of electric current activity,the voltage became higher,and the visual-spatial combined cortex was no obvious current activity.Conclusions The abnormal behavior of people during movement is related to the sudden shielding of sensory perception by the brain and the production of more cognitive activities related to behavioral strategies.If people’s ability,physical strength and preparation are insufficient,the normal“neurobehavioral”linkage mechanism will be destroyed,leading to movement disorder.
