Objective.基于脑电图（EEG）的脑机接口（BCI）已被证明可以准确地检测心理活动，但要获得高水平的控制需要大量的用户培训。此外，脑电信号具有低信噪比和低空间分辨率。本研究的目的是比较两种类型的脑机接口之间的准确性在第一次记录会话。记录EEG和三极同心环电极（TCRE）EEG（tEEG）脑信号，并用于控制一维光标移动。Approach.八名人类受试者被要求在一次记录过程中想象“左手”或“右手”的运动，以使用TCRE和圆盘电极控制计算机光标。主要结果。所获得的结果显示，与盘状电极（30%-86%）相比，使用TCREs（44%-100%）的准确度有显著提高。意义这项研究开发了第一个基于tEEG的BCI系统，用于实时一维光标移动，并在很少的训练下表现出高准确性。
Objective. Brain-computer interfaces (BCIs) based on electroencephalography (EEG) have been shown to accurately detect mental activities, but the acquisition of high levels of control require extensive user training. Furthermore, EEG has low signal-to-noise ratio and low spatial resolution. The objective of the present study was to compare the accuracy between two types of BCIs during the first recording session. EEG and tripolar concentric ring electrode (TCRE) EEG (tEEG) brain signals were recorded and used to control one-dimensional cursor movements. Approach. Eight human subjects were asked to imagine either 'left' or 'right' hand movement during one recording session to control the computer cursor using TCRE and disc electrodes. Main results. The obtained results show a significant improvement in accuracies using TCREs (44%-100%) compared to disc electrodes (30%-86%). Significance. This study developed the first tEEG-based BCI system for real-time one-dimensional cursor movements and showed high accuracies with little training.
