Maybe @cwindfmri.bsky.social @tmsfmri.bsky.social can suggest some most current TMS safety literature.
<TMS best practices>
Hi folks,
Could you please point me to the most up-to-date consensus paper you're aware of relating to TMS safety? Number of pulses / intensities / frequencies / other parameters etc.
I want to take as wide a look at the literature as possible.
Please repost for visibility!

Great & important work. That said, one area that is still overlooked is data quality. This is harder to model because contrast-to-noise can be application specific, but it's critical when designing large studies. Better data means similar results with smaller N or shorter scans. 1/2

Great session at #OHBM2025 on Clinical applications of brain mapping across the lifespan. Chris Tailby's summary of www.epilepsyproject.org.au is a great example of type of large-scale work that's necessary to make fMRI useful in normative clinical practice.
