#---------- Data info
10 datasets of EEG recorded from p21 Wistar rats with electrodes positioned on the cranium.
These data were originally published in Quairiaux et al. (2010), where a full description of the methods can be found.
50 Left/Right (Gauche/Droite, excuse my French) whisker stimulations (some lacking in one animal).
Signals were referenced to an electrode placed above the cerebellum, online filtered 1-500 Hz, and digitized at 2 kHz.

Each directory contains data files from one animal: Epochs for left ('G') and right ('D') stimulation plus an average for each condition.
Each file contains 15-channel epicranial EEG, the reference electrode has been removed.
Stimulus onset is at time-frame 120.
The EEG files (.eph) are plain text files with a header: nr of channels, nr of time frames, sampling rate (Hz).
Openable in Cartool software, freely available here: https://sites.google.com/site/fbmlab/cartool

Electrode layout file: electrodeLayout_15chan.els
A text file with 15 electrode coordinates, can be linked to the .eph files for topographic ERP views using Cartool software.

The electrode layout is shown in rodent_15ch_electrodeLayout_left-right.PNG
For left stimuli, e4 is the electrode over contralateral S1, for right stimuli it is e12.

#---------- 数据集信息
本数据集包含10组来自p21系Wistar大鼠的颅骨脑电图（Electroencephalogram, EEG）数据，电极安置于大鼠颅骨表面。
该数据集最初发表于Quairiaux等人2010年的研究中，完整的实验方法描述可参见该文献。
实验包含50次左右胡须刺激（Gauche为法语“左”，Droite为法语“右”，作者此处使用法语标注，见谅）。
所有信号以小脑上方的电极作为参考电极，在线滤波频段为1~500Hz，采样率为2kHz。

每个子文件夹对应一只大鼠的数据文件：包含左侧（'G'）和右侧（'D'）胡须刺激的脑电分段数据，以及两种刺激条件下的平均脑电数据。
每个数据文件包含15通道颅骨脑电图数据，已移除参考电极。
刺激起始时刻对应时间帧120。
EEG数据文件（.eph）为纯文本格式，文件头包含通道数、时间帧数及采样率（单位：Hz）。
该文件可使用Cartool软件打开，该软件可通过以下链接免费获取：https://sites.google.com/site/fbmlab/cartool

电极布局文件：electrodeLayout_15chan.els
该文本文件包含15个电极的坐标信息，可通过Cartool软件与.eph格式的脑电文件关联，用于绘制事件相关电位（Event-Related Potential, ERP）地形图视图。
电极布局示意图可见于rodent_15ch_electrodeLayout_left-right.PNG文件。
对于左侧胡须刺激，e4电极对应对侧初级躯体感觉皮层（S1）；对于右侧胡须刺激，e12电极对应对侧初级躯体感觉皮层（S1）。
