In Second Gig (the second season of the anime) they do go over her past more and it reveals that she was a little girl that survived a plane crash (?) and was one of the first children to have a fully cybernetic body. That season explores a lot about her relationship with her past and present identities, motivations, and principles. It is one of my favorite pieces of media.
She definitely has a human brain; the central theme is that she doesn’t know her own identity
