The combination of TMS with other neuroimaging technologies such as PET, EEG and fMRI is particularly promising for our understanding of brain network interactions. Specifically, these imaging techniques provide a richer and more sensitive toolbox for assessing the results of brain stimulation, particularly in non-eloquent areas. Furthermore, because neuroimaging data is amenable to functional connectivity and network analysis techniques, the combination of brain stimulation and neuroimaging permits the study of the effects of brain stimulation techniques on widespread networks composed of a number of different cortical regions. In addition, the time course of activity changes in these different regions can be used to assess the causal relationship between them.
