Assessing suitability of ultra-low-field MRI for TES electric field models

Alexander R. Guillen, Yu Huang, Dennis Q. Truong…·Abhishek Datta

This study compares electric field models derived from ultra-low-field (ULF) and 3T MRI scans, finding significant differences in cortical regions but less so in deeper brain structures.

On the need of individually optimizing temporal interference stimulation of human brains due to inter-individual variability

Tapasi Brahma, Alexander R. Guillen, Jeffrey Moreno…·Yu Huang

This paper shows that individually optimizing temporal interference stimulation improves focality in deep brain regions compared to common montages, with variability due to head anatomy and tissue conductivity.
