Looking at the different currents induced by TMS and their respective thresholds will be useful to better understand the biphysical mechanisms and expand TMS applications. 
Thanks to the @NIH Brain Initiative, @NIH_NINDS and @NIBIBgov for funding this work.

Current source density analysis of the laminar data helps localize the current sources to be near the near the bend of the climbing fibers and near the axon initial segment of the Purkinje cells

Why has it been challenging to stimulate neurons with TMS in in vitro preparations?

We show how conductivity boundaries can have significant effects on the effective electric field inside the tissue.
