Complex electroencephalographic (EEG), stabilographic and psychological study was executed during the number dual tasks performance--postural control and calculation in 25 healthy volunteers (age 25 ± 0.7). Successful performances of dual tasks required a high usage of cognitive resources, such as memory and attention as well as good motor command and low level of anxiety. Two EEG-markers of successful dual tasks performance were revealed. An increase of EEG coherence for long diagonal pairs of leads between frontal and parieto-occipital areas was observed. Additionally a decrease of EEG coherence for short pairs of leads was revealed. The poor performance of dual tasks was accompanied by an increase of EEG coherence between local pairs of leads for different spectral bands.
在25名健康志愿者(年龄25±0.7岁)执行数字双重任务(姿势控制和计算)期间,进行了复杂的脑电图(EEG)、稳定图和心理学研究。双重任务的成功执行需要大量使用认知资源,如记忆和注意力,以及良好的运动指令和低焦虑水平。揭示了双重任务成功执行的两个脑电图标志物。观察到额叶和顶枕区之间长对角导联对的脑电图相干性增加。此外,还发现短导联对的脑电图相干性降低。双重任务表现不佳伴随着不同频谱带局部导联对之间脑电图相干性的增加。
