Jul 6, 2016 - Import the CSV file as a MATLAB matrix using the following. Channel locations are useful for plotting EEG scalp maps in 2-D or 3-D format.

This function is not very general. The reshape will work only for 65 EEG channels (and only if the electrodes are correctly labeled) Concerning the note: 'Note: for some reason, bdf format specifies separate sets of 'fs', 'gain', 'ChanDim', and 'prefiltering' or every EEG channel. This function returns these values for the first channel (electrode) only! This is a big mistake for chanDim: for instance with biosemi you can also record peripheral signals that are not in uV (like electrodermal activity in nS).

Since there is no public database for EEG data to our knowledge, we have decided to release some of our data on the Internet (if you know any database or if you want us to add a link to data you are distributing on the Internet, send us an email at arno sccn.ucsd.edu). Below is a collection of 32-channel data from 14 subjects (7 males, 7 females) acquired using the Neuroscan software. Subjects are performing a go-nogo categorization task and a go-no recognition task on natural photographs presented very briefly (20 ms). Each subject responded to a total of 2500 trials. Data is CZ referenced and is sampled at 1000 Hz (total data size is 4Gb; more details are given later).

Before starting with this data, we review below some other alternatives. Datasets in Matlab (from the tutorial) are •: 3 experiments with multiple subjects (12).

Microsoft Sway.

•: One subject (80 trials) from a visual attention task (32-channel; Matlab format). •: 5 subjects with and 2 conditions (64 channels, Matlab format).

•: more than 100 datasets available. Other EEG databases or datasets known to us are •: 12,000 patients 16-channel EEG EDF files •: a collection of file and sleep scoring on 8 people (only 5 EEG channels).

•: From Gerwin Schalk's team at the Wadworth center in Albany, NY. • Various experiments are features. •: 122 subjects recorded using 64 channel (Alcoholic and Controls performing a visual matching task). The limitation of this data is that only data epochs (0 to 1 second after stimulus presentation) is available. After decompressing the files, Matlab scripts to import to EEGLAB are available here ( and ). •:EEG (and other modalities) emotion recognition. •: This EEG experiment was named 'Emotion Detection in the Loop from Brain Signals and Facial Images'.

•: example data from a spatial EEG attention experiment. •: A very comprehensive database of epilepsy data files. •: a few small files (text format). •: Sleep EEG from 8 subjects (EDF format). •: Motor imagery data for BCI project (Matlab files). •: P300 data used for BCI project (Matlab format). •: P300 data saved in the Brain Vision Exchanged format.

About 100 datasets. •: about 60 datasets. •: few trials of EEG data from rats, visual evoked potential, epilepsy, and rest.

•: few seconds of 64-channel EEG recording from an alcoholic patient. •: 10 patients with 750 trials each Some datasets used in Brain Computer Interface competitions are also available at • • • You may also look at a ciculated on the EEGLABLIST that may contain other databases.
