Design of an Experimental Platform for Hybrid EEG-fMRI Neurofeedback Studies

Neurofeedback (NF) can be defined as the self-regulated change of a particular brain activity that is reflected in the change of a neural signal or a combination of neural signals such as EEG, fMRI, MEG, etc. There exist a variety of unimodal (i.e. EEG or fMRI) NF researches, but very few with multimodal NF applications. This is primarily because of the associated technical burdens. The purpose of this abstract is to give a technical description of the hybrid EEG-fMRI system that we have developed for our NF experiments as part of the project Hemisfer, including the hardware/software components and their roles.
