Commentary on: Deng et al., Electric field depth-focality tradeoff in transcranial magnetic stimulation: Simulation comparison of 50 coil designs

摘要

The review by Deng et al. in this edition modeling 50 theoretical and practical coils [1 ] is a comprehensive and important article that compares the electric field depth-focality profile of various coils using a spherical head model. The use of a spherical model facilitates the definition of a simple and universal metric framework for a convenient comparison of the depth and focality characteristics of all TMS coils. Yet, the gain in generality and simplicity of this approach comes at the expense of losing some valuable features that must be acknowledged.
