[Eeglablist] Does EEGLAB work with EMOTIV systems

[Stefan Debener]

Hi Josh,

You can use standard EEGLAB import routines to import EMOTIV data 
recorded with their Testbench software (gdf or edf format). However, 
trigger timing with Testbench is terrible and simply not good enough for 
ERPs. We currently use Openvibe (http://openvibe.inria.fr/) for data 
recording, stimulation, and online analysis, and EEGLAB for offline 
analysis. We modified the EMOTIV hardware a little bit, and the result 
is a new system that can be used to produce high quality ERPs and 
single-trial EEG data in truly mobile recording situations (such as 
walking outdoors). Our first paper reporting this is in press in 
Psychophysiology. I am happy to send it to anybody interested, upon request.

Debener, Minow, Emkes, Gandras & De Vos (2012). How about taking a 
low-cost, small and wireless EEG for a walk? Psychophysiology (in press).

Best,
Stefan
