For simultaneous recording of spike signal and functional magnetic resonance imaging (fMRI) response, both MR-compatibility and performance of electrophysiological signal acquisition of the electrode matters. Previously, we have designed a flexible polyimide-based microelectrode array which has good biocompatibility, as well as high and stable signal-to-noise ratio for chronic recording. This study evaluated the MR-compatibility and recording performance of microelectrode array in the 7T research system (Siemens, Erlangen, Germany). The results suggest that it has the potential to facilitate simultaneous spike-recording during MR scanning in 7T.
