Are the patterns overlapping in any areas and what do they signify?
Hi Rebecca...
By combining EEG (high temporal resolution) and fMRI (high spatial resolution) one can get extremely useful information on when and where any special brain activity occurred. There are plenty of methods to extract the information from two modalities, easiest it to correlate EEG and fMRI signals. As a result only the voxels will show up that their HRF response is correlated with ERP response of EEG, for instance.
That makes sense. I'm currently looking at sLoretta for EEG but unsure of what to correlate that data with concerning fMRI or MRI. Do you suggest a program to correlate data to each other?
Well... I would suggest MATLAB to do that. It is the easiest that you can handle your analysis as you like. I am sure there might be other programs too which are more user friendly, but I am unfortunately not aware at this time.
I assume the EEG recording is being done simultaneous with the fMRI session?
Hi Rebecca,
There are many different ways of combining EEG and fMRI data. An overview is given here: http://www.ncbi.nlm.nih.gov/pubmed/23732883 . I can send you a pdf if you can't access it through pubmed. Let me know.

Hi Rebecca,
Are you talking about simultaneous recording of EEG and fMRI data? If so, be careful how to remove artefacts from your data, since i guess this is one of the most critical steps before looking at possible relations between EEG and fRMI. In our lab, we tused EEGLAB functions to get rid of artifacts. As Mehdi Ordikhani-Seyedlar pointed out, I would recommend MATLAB for further analyses.
Best, Lisa
They will be separate to avoid artifact Lisa. Wonderful. I'll be looking at MATLAB this weekend. I'm using Neuroguide, BrainDx, and sLoreta currently.
