BCI Competition IV IIA

该数据集包含了9名健康参与者在两个阶段内进行的四种运动想象任务的脑电图数据。数据采集的采样率为250赫兹，任务内容包括想象左手、右手、双脚以及舌头的动作。该数据集涵盖了22个通道，每个阶段包含288个试验。任务的目的是进行运动想象分类。

This dataset contains electroencephalogram (EEG) data collected from 9 healthy participants who completed four motor imagery tasks across two stages. The data was acquired at a sampling rate of 250 Hz, and the tasks include imagining movements of the left hand, right hand, both feet, and tongue. This dataset comprises 22 EEG channels, with 288 trials per stage, and is intended for motor imagery classification research.
