Abstract

Personality traits of users can affect the success in controlling brain–computer interfaces (BCIs), and the activity of right and left brain structures may differ depending on personality traits. Earlier, it was not known, how the success of BCI control with different personality traits is associated with interhemispheric asymmetry. In this work, the dependence of the success of imagination of movements, estimated by the success of recognition of EEG signals during imagination of hand movements compared to rest state, on the user’s personal characteristics was studied. It is shown that in single control of BCI by naive subjects, recognition success in imagining right-hand (RH) movements was higher in expressive sensitive extroverts, and in imagining left-hand movements (LH) it was higher in practical, reserved, skeptical, and not very sociable persons. It is suggested that this phenomenon may be based on interhemispheric differences in dopamine level and in the way of encoding movement information.

脑机接口用户在手部运动想象中的半球间不对称性和人格特征

摘要

用户的个性特征会影响控制脑机接口（BCI）的成功与否，左右脑结构的活动可能因个性特征而异。早些时候，不知道具有不同人格特征的 BCI 控制的成功如何与半球间不对称有关。在这项工作中，通过与静止状态相比，手部运动想象过程中脑电信号的识别成功来估计运动想象成功对用户个人特征的依赖性。结果表明，在幼稚受试者对 BCI 的单次控制中，表现力敏感的外向者在想象右手 (RH) 运动中的识别成功率更高，而在想象左手 (LH) 时，在实际、含蓄、怀疑的情况下识别成功率更高, 而不是很善于交际的人。有人认为，这种现象可能是基于多巴胺水平的半球间差异和编码运动信息的方式。
