connectivity measures
Posted: Fri Apr 13, 2012 11:40 am
Dear OpenVibe developers,
What about developing a box and/or pipeline for estimating functional connectivity measure(s) between channels (electrodes)? For example, phase coherence or imaginary phase-coherence (volume conduction independent). A more basic measure could be calculating the correlation coefficient between spectral power of different EEG frequencies/electrodes. Functional connectivity measures could help explore and introduce more complex protocols for BCI and/or neurofeedback applications, which may potentially be informative for the accurate identification of brain state(s).
Thanks a lot for the consideration!
Best wishes,
Tomas
