Are you familiar with centers that replaced fMRI with rTMS for clinical language mapping? I wonder how common the trend might be in surgical planning. Thank you!
I'm not familiar with centers which might have applied this, but my thoughts on the matter concern why you wouldn't use fmri guided rtms. There are a lot of navigation devices that allow this to be easily carried out. As for surgical planning, whilst these are both strong ways of mapping cognitive functions it's important to consider the properties of the magnetic field generated by tms and what this means for spatial localisation. The field produced, although more accurate in recent years, is still wide enough (the windings don't help, even if you are using a figure of eight) to have residual effects on neighbouring portions of the cortex. I would imagine that fine spatial navigation is of importance here.
