Studying neural activation patterns is critical in the understanding of neuromodulation in transcranial electrical stimulation methods (TES). This research focuses on simulations of neural excitability of a realistic axon model obtained from DTI tractography of the trigeminal nerve, in comparison to a linear axon model obtained from literature, in presence of induced electric fields found from realistic FEM (finite element method) modelling of TES. The differences observed highlight the need for use of realistic trajectories in neural simulations and provide means for patient specific personalized studies.
