Synopsis

Keywords: Multimodal, fMRI (task based), EEG, EEG recording, MRI compatible EEGA cost-effective, 8-channel, MRI-compatible optical EEG prototype was implemented and tested. The protoype has the potential to be especially suited for low-field MRI applications. The system uses Photrode^TM technology, a high impedance device that can pick up signals without the need for "wet" contact with the skin. The minimum resolvable voltage of the modulator was ~ 12.5 uV, sufficient for most EEG waves.
