Functional Magnetic resonance electrical impedance tomography (fMREIT) has the potential to directly image neural activity. In our tests, we used the Aplysia abdominal ganglion (AAG) as a neuronal activity source. Potassium chloride (KCl) was used to modulate neuronal activity. Analysis of magnitude images, subtracted MREIT phase images and Laplacian of MREIT Bz images was performed to evaluate the difference in MREIT images with and without neuronal activity.
