Abstract

Introduction: The nervous system is the master of the human body functions. It has been stated that the frontal lobe is responsible for the global and fine coordination, and might be more active than other areas of the cortex. In such a way, the present study aimed at identifying if the frontal lobe is more active than the somatossensorial area during tasks of global coordination. Materials and Methods: Braintech 3.000 was used (EMSA Medical Instruments, Brazil) for collecting the electroencephalographic signal. Results: The tests of global coordination, oculo-manual coordination were the electrode F3 (1.799±0.225mV) versus C3 (1.789±0.218mV), F4 (1.815±0.223mV) versus C4 (1.828±0.227mV), footeye coordination F3 (2.735±0.278mV) versus C3 (2.702±0.280mV) and F4 (2.821±0.267mV) versus C4 (2.763±0.258mV). None of the results presented any difference in the ANOVA one-way with 0.05 sensitivity. Discussion: The results showed great activity of the frontal cortex; however, there is an activation of the same magnitude in the somatossensorial area, suggesting an interregional coupling of information during tasks of global

全球运动协调测试期间额叶和顶叶之间的同步能量

简介神经系统是人体功能的主宰。有学者指出，额叶负责整体和精细协调，可能比大脑皮层的其他区域更活跃。因此，本研究旨在确定在完成整体协调任务时，额叶是否比体表区域更活跃。材料与方法使用 Braintech 3.000（巴西 EMSA 医疗仪器公司）采集脑电信号。结果全局协调、眼动协调测试中，电极 F3（1.799±0.225mV）与 C3（1.789±0.218mV）、F4（1.815±0.223mV）对 C4（1.828±0.227mV），脚眼协调 F3（2.735±0.278mV）对 C3（2.702±0.280mV）和 F4（2.821±0.267mV）对 C4（2.763±0.258mV）。在灵敏度为 0.05 的单因素方差分析中，所有结果均无差异。讨论结果表明，额叶皮层的活动量很大；但是，躯体感觉区也有相同程度的激活，这表明在执行全局性任务时，区域间的信息耦合也很重要。
