I'll give up with you ... I haven't the vaguest bloodly clue either, but I suppose I could google it ... if I cared.
Neuroanatomy is not my strong suit ... also, I don't get much contact with any of the cool, fancy, diagnostic tests or anything like that where I might be prompted to actually learn this stuff.
I'm the equivalent of a field EMT or paramedic in the psych business ... if somebody looks crazy, they're crazy ... I patch 'em up and keep 'em breathing long enough to get them to a "real" doctor.
yes, I know what's wrong with them, and what will probably help in the long term, but I don't do those parts ... kinda of like a paramedic has an understanding of anatomy, but doesn't perform surgery.
