We introduce a new “realistic” head model for stroke patients to improve the accuracy of TMS and tES simulations.

We hope this study contributes to ongoing efforts toward the personalization of brain stimulation protocols for stroke rehabilitation.

This work also represents one of the first steps toward developing the next generation of head models for SimNIBS, and we look forward to contributing further to this effort at DRCMR.

Abstract Introduction:

"Transcranial direct current stimulation (tDCS) is tested as tool for post-stroke rehabilitation in aphasia, and individualized simulations of tDCS-induced electric fields (E-fields) can guide its application. However, the accuracy of simulations is challenged by complex and variable tissue properties of stroke lesions. Here, we assessed the impact of stroke lesions on tDCS-induced E-fields realistically in terms of lesion size, shape, and conductivity."
