On the importance of using both T1-weighted and T2-weighted structural magnetic resonance imaging scans to model electric fields induced by non-invasive brain stimulation in SimNIBS

Computational modeling of the electric fields (E-fields) induced by non-invasive brain stimulation has become increasingly popular and widely implemented in the past decade. E-field modeling is an informative tool that enables researchers to better understand the effects of non-invasive brain stimulation techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) on the cortical and subcortical level. To date, E-field modeling studies have had widespread applications, such as informing how stroke damage alters cortical activation from TMS and tDCS [1], elucidating the impact of different tDCS montages on the magnitude and focality of stimulation [2,3], and unravelling dose-response relationships between tDCS-induced E-field strength and the degree of behavioral improvement [4].
