Computational modeling of dorsal root ganglion stimulation using an Injectrode

S. Bhowmick, R. D. Graham, N. Verma, J. K. Trevathan, M. Franke, S. Nieuwoudt, L. E. Fisher, A. J. Shoffstall, D. J. Weber, K. A. Ludwig, S. Lempka

The paper models the Injectrode system to determine how design parameters affect neural activation, finding that larger surface area reduces pain-related activation.
