Although it's not excatly brain surgery...trepanation is a much earlier form of neurological "research." or rather...experimentation...
I think evidence goes as far bak as the Mesolithic...for those who don't know what trepanation is, basically it's when a hole (sometimes multiple
holes over a lifetime) is created in the skull to relieve pain or pressure...
