摘要:目的 从空间和时间两个角度探究足球颠球技能学习过程中脑灰质体积变化特征,为揭示运动技能学习的神经机制提供新证据。方法 选取111名大学生为研究对象,依据自愿参加训练原则分为实验组和对照组,实验组实施70次的足球颠球学习,对照组常规学习生活。使用结构磁共振成像技术采集基线、球颠35次、球颠70次三个时间点的脑影像数据,并采用基于体素的形态学测量方法分析学生脑灰质体积变化。结果 (1)70次足球颠球学习使得相关脑区灰质体积改变,具体空间特征为:左侧小脑6区、左侧舌回脑区和右侧距状裂周围皮层区域的灰质体积显著增加;(2)70次足球颠球学习过程中脑灰质体积变化存在差异,具体时间特征为:前期阶段(前35次),右侧中央后回、右侧额中回、右侧内侧额上回、左侧眶部额上回、双侧枕下回、双侧枕中回、双侧回直肌和右侧小脑下部区域灰质体积减少,小脑蚓部灰质体积增加;后期阶段(后35次),左侧枕下回、左侧海马旁回和左侧嗅皮质区域灰质体积减少。结论 足球颠球技能习得与负责视觉信息和肢体协调的相关脑区的灰质体积增加有关;足球颠球学习能够引起与视觉信息、肢体协调和运动控制等有关的脑区的灰质体积变化,其呈现从脑的前部向后部转移的动态特征。

Abstract: Objective To provide new evidence to explain the neural mechanism of motor skill learning through investigating the characteristics of gray matter volume changes in football juggling learning from both spatial and temporal perspectives.Method To select 111 college students as the research objects.According to the principle of voluntary training,they are divided into experimental group and control group.Among them,the experimental group carried out 70 sessions of football juggling learning,and the control group was engaged in their regular academic and personal activities over the same timeframe.Structural magnetic resonance imaging was used to collect brain imaging data at three time points:baseline,35 sessions,and 70 sessions.Voxel-based morphometry (VBM) was used to analyze the changes of gray matter volume.Results (1) The volume of gray matter in the relevant brain area changed after 70 sessions of football juggling learning.The specific spatial characteristics were as follows:the gray matter volume of the left cerebellum 6,the left lingual gyrus and the right calcarine fissure and surrounding cortex area increased significantly.(2) There were differences in the change of gray matter volume during 70 sessions of football juggling learning.The specific temporal characteristics were as follows:in the early stage (the first 35 sessions),the gray matter volume decreased in the regions of the right postcentral gyrus,the right middle frontal gyrus,the right superior frontal gyrus (medial),the bilateral inferior occipital gyrus,the bilateral middle occipital gyrus,the bilateral gyrus rectus and the right cerebellum,while the gray matter volume of the vermis increased.In the later stage (the last 35 sessions),the volume of gray matter decreased in the left inferior occipital gyrus,the left parahippocamal gyrus and the left olfactory cortex.Conclusion The acquisition of football juggling is associated with an increase in the volume of gray matter in brain regions associated with visual information and physical coordination.The gray matter volume of the related brain areas such as visual information,limb coordination and motor control can be changed by football juggling learning,and it shows the temporal characteristic of the transfer from the front to the back of the brain.

Key words: football juggling, gray matter, temporal and spatial characteristics, structural magnetic resonance imaging
