Word is awkward for this. (At least the offline versions of Word are---I've never tried the online ones.) Word does have a "track changes" feature, which is invaluable when you have multiple authors, at least in the absence of 'traditional' source control tools. I don't think many neuroscientists have tried a LaTeX-git workflow and rejected it---I think the learning curve of LaTeX and git are steep enough that few have tried it. I myself prefer LaTeX, but I think you'll admit it also has its frustrations. And any time I suggesting using it to my neuroscience coworkers, they looked at me like I had lobsters coming out of my ears.
