The neuroscience tag was recently introduced in this question. We already have a neurobiology tag that is actively used. However, most of those questions could/hold be tagged neuroscience. In fact, the early questions I asked were only tagged as neurobiology because there was not a general neuroscience tag.
Do we need both the neurobiology and neuroscience tags? Or can we just have one (I would vote for neuroscience since it is more general)? If we have two tags, then how to decide between tagging something as neurobiology vs. neuroscience?
