From: Individual head models for estimating the TMS-induced electric field in rat brain

A three-compartment BEM model of the rat head. The compartments are defined by the body outline of the front half of the rat, the skull, and the eyes. The induced E-field was computed on the blue surface, which corresponds to the estimated surface of the brain and the brainstem. The red points indicate the tested locations of the coil centre, with the central point highlighted. Here, an example coil is shown in the posterior–anterior (PA) orientation at the central location.
