Building Brain Invaders: EEG data of an experimental validation
This provides a standardized dataset for researchers in neuroscience and brain-computer interfaces, though it is incremental as it builds on existing experimental setups.
The authors tackled the need for accessible EEG data by creating and publicly releasing a dataset of electroencephalographic recordings from 25 subjects using a Brain-Computer Interface based on the P300 event-related potential, with data available in mat and csv formats and Python code for manipulation.
We describe the experimental procedures for a dataset that we have made publicly available at https://doi.org/10.5281/zenodo.2649006 in mat and csv formats. This dataset contains electroencephalographic (EEG) recordings of 25 subjects testing the Brain Invaders (Congedo, 2011), a visual P300 Brain-Computer Interface inspired by the famous vintage video game Space Invaders (Taito, Tokyo, Japan). The visual P300 is an event-related potential elicited by a visual stimulation, peaking 240-600 ms after stimulus onset. EEG data were recorded by 16 electrodes in an experiment that took place in the GIPSA-lab, Grenoble, France, in 2012 (Van Veen, 2013 and Congedo, 2013). Python code for manipulating the data is available at https://github.com/plcrodrigues/py.BI.EEG.2012-GIPSA. The ID of this dataset is BI.EEG.2012-GIPSA.
