Research in the field of Brain-Computer Interfaces (BCIs) has increased exponentially over the past few years, demonstrating their effectiveness and application in several areas. The main purpose of the present paper was to explore the relevance of user engagement during interaction with a BCI prototype (Neuro-Upper, NU), which aimed at brainwave synchronization through audio-visual entrainment, in the improvement of cognitive performance.
This paper presents findings on data collected from a sample of 18 subjects with clinical disorders who completed about 55 consecutive sessions of 30 min of audio-visual stimulation. The relationship between engagement and improvement of cognitive function (measured through the Intelligence Quotient - IQ) during NU neuromodulation was evaluated through the Index of Cognitive Engagement (ICE) measured by the Pope ratio (Beta / (Alpha + Theta), and Arousal [(High Beta + Low Beta) / (High Alpha + Low Alpha)].
A significant correlation between engagement and IQ improvement, but no correlation between arousal and IQ improvement emerged, as expected.
Future research aiming at clarifying the role of arousal in psychological disorders and related symptoms will be essential.
在过去的几年中，脑机接口（BCI）领域的研究呈指数级增长，证明了它们在多个领域的有效性和应用。本文的主要目的是探讨在与脑机接口原型（Neuro-Upper，NU）交互过程中用户参与度的相关性，该原型旨在通过视听同步实现脑电波同步，从而提高认知表现。
本文介绍了从 18 名患有临床疾病的受试者中收集的数据结果，这些受试者完成了约 55 次连续 30 分钟的视听刺激。通过 Pope 比（Beta / (Alpha + Theta）测量的认知参与指数（ICE）评估了在 NU 神经调节过程中参与度与认知功能（通过智商 - IQ 测量）改善之间的关系，而唤醒度则通过（高β+低β）/（高α+低α）来衡量。
正如预期的那样，结果显示参与度与 IQ 改善之间存在显著相关性，但唤醒度与 IQ 改善之间没有相关性。
未来的研究旨在阐明唤醒度在心理障碍和相关症状中的作用将是至关重要的。
