Abstract:
It has been proposed that the direct imaging of neuronal currents is possible using magnetic resonance imaging techniques. The ability to detect and map neuronal currents in the brain is of great interest in understanding both health and diseases. Current contrast techniques challenge the ability to directly measure or detect nerve activity. Investigations are currently underway to search for better contrast techniques that would allow researchers to directly detect neuronal currents. The focus of this research paper is to analyze the presently available contrast methods in their ability to directly detect neuronal currents. Our computer simulations modeling the movement of particles in a crossed magnetic and electric field provide insight into the current capabilities of Lorentz Effect Imaging. We have found that modeling LEI with magnetohydrodynamic fluid flow, provides a more robust method of contrast imaging.
