While studying a neuroscience-adjacent MSc at UCL in London during the mid-2010s, senior academics would regularly recommend Wikipedia as an excellent primer for neuroanatomy. They wouldn't do it for people on actual neuroscience courses, who needed to know things in more detail, but they were very complimentary about the accuracy of the information on there.

I find math topics to be insufferable. They are written to be as theoretical as possible and borderline useless if you do not already know the topic at hand.
