Real-time processing of EEG/MEG data with Matlab

Real-time processing of EEG/MEG data with Matlab

We are working on the real-time support for data analysis (feature extraction and classification) in FieldTrip. Besides feature extraction and classification, which are both needed for BCI and neurofeedback applications, we have implemented support for real-time processing of EEG/MEG data in MATLAB in general.

The FieldTrip buffer provides a real-time interface between MATLAB and streaming EEG/MEG data

Integration with other software and with acquisition systems

Closing the loop

For a real-time BCI system, it is important that a control signal somehow can be used to close the loop towards the subject. Here you can find a description on the options that you have for closing the loop from within your Matlab-based BCI application.
