tags: fMRI, MRI, --> add dMRI? you also said electrophysiology is already there (just not yet linked IIRC)
maybe it would be great to either have a complete choice list of tags in a TAGs.md file, where people can see all used ones (for max consistency) and make a PR to add a missing one which in turn can then be used by future submissions.
