EEG Semantic Imagination and Perception Dataset

This dataset consists of electroencephalography (EEG) signals acquired with a 124 EEG ANT-Neuro device.

### Participants and Sessions
There are 13 participants included, ten performed one session and three performed two sessions. All participants had normal or corrected vision and hearing, apart from sub-16.

### Task
The task consisted of imagining and perceiving stimuli from three modalities; visual pictorial, visual orthographic (writing) or auditory. Each of the stimuli belonged to one of three categories: guitar, flower and penguin. These categories were selected based on being semantically dissimilar to one another, and because there were all of 2 syllables.

### Dataset Versions
The dataset provided consists of the raw EEG data, a pre-processed version, and an epoched version.

本数据集包含通过124通道ANT-Neuro脑电设备采集的脑电图（electroencephalography, EEG）信号。

### 参与者与实验场次
本数据集共纳入13名参与者，其中10名完成1次实验场次，3名完成2次实验场次。所有参与者均具备正常或经矫正的视听能力，编号为sub-16的参与者除外。

### 实验任务
实验任务包含对三种模态的刺激进行想象与感知：视觉图像类、视觉正字法（文字书写类）以及听觉类刺激。每类刺激均隶属于以下三个语义类别之一：吉他、花卉与企鹅。选择这三类刺激的依据为：三者语义互不相似，且均为双音节词汇。

### 数据集版本
本次提供的数据集包含原始脑电图数据、预处理版本数据以及分段版数据。
