Review
Parameterization of transcranial magnetic stimulation
Michael T Rubens et al. J Neurophysiol. 2012 Mar.
Abstract
A recent study (Di Lazzaro et al. J Neurophysiol 105: 2150-2156, 2011) describes the findings from a rigorous comparison on the effects of several popular variations of transcranial magnetic stimulation (TMS) protocols. The results demonstrate that excitatory and inhibitory neural networks may be independently modulated based on TMS protocol selection. Moreover, the within-group replication of multiple between-group experiments suggests that independent evaluations of TMS parameters will continue to inform and guide future TMS research.

Factors that influence the effects of transcranial magnetic stimulation (TMS). Mechanical factors (yellow labels) describe TMS parameters that may be adjusted for a desired outcome. Biological factors (green labels) determine where to stimulate and may help guide the selection of specific TMS parameters. All of these factors comprise a TMS protocol, and manipulating any one of them may result in differential outcomes (for details, see text). However, mechanical factors are the most straightforward to address when planning a study, whereas biological factors require a priori knowledge of the neural system to be stimulated.
