The aim of this study was to verify changes in absolute power (qEEG), in theta, during the catch of a free falling object. The sample consisted of 10 healthy individuals, of both genders, with ages between 25 and 40 years. A three-way ANOVA followed by Post-Hoc analysis was applied. The results demonstrated main effects for time and position. In conclusion, a motor task that involves expectation produces deactivation of non-relevant areas in the ipsilateral hemisphere of the active limb. On the other hand, the patterns of results showed activation in areas responsible for planning and selection of motor repertoires in the contralateral hemisphere.
本研究的目的是验证在接住自由落体物体过程中，θ频段绝对功率（定量脑电图）的变化。样本包括10名年龄在25至40岁之间的健康男女个体。采用了三因素方差分析并随后进行事后分析。结果显示了时间和位置的主效应。总之，一项涉及预期的运动任务会使主动肢体同侧半球的非相关区域失活。另一方面，结果模式显示对侧半球中负责运动技能计划和选择的区域被激活。
