Abstract

We present an EEG dataset recorded from 22 neurologically healthy volunteers (12 native Russian speakers and 10 native Spanish speakers) during overt and covert articulation of six spatial-direction words. Monopolar EEG signals were acquired from 38 electrodes positioned according to the international 10-10 system using a Neurovisor-BMM-52 (NVX) amplifier at 500 Hz. In a subset of participants, electromyography (EMG) was simultaneously recorded from the masseter muscle and laryngeal region to exploratorily characterize articulatory muscle activation. Exploratory spectral and coherence analyses, together with classification using standard machine learning methods (Random Forest, SVM, LDA), confirm the presence of condition-specific neural activity distinguishable by standard classifiers (best accuracy 78 ± 4%). The dataset is intended to support the development and benchmarking of algorithms for inner speech recognition in brain-computer interface applications.

基于脑电图的定向词识别脑机接口(BCI)数据集。
我们展示了22名神经健康志愿者(12名母语为俄语的人和10名母语为西班牙语的人)在公开和隐蔽地发音6个空间方向词时的脑电图数据集。使用500 Hz的Neurovisor-BMM-52 (NVX)放大器,根据国际10-10系统定位38个电极,获取单极脑电图信号。在一部分参与者中,同时记录咬肌和喉区的肌电图(EMG),以探索性地表征关节肌的激活。探索性光谱分析和相干性分析,以及使用标准机器学习方法(随机森林、支持向量机、LDA)进行分类,证实存在可由标准分类器区分的特定条件的神经活动(最佳准确率为78±4%)。该数据集旨在支持脑机接口应用中内部语音识别算法的开发和基准测试。

期刊介绍: Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data. The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
