Dear jheem: at the moment, I haven't the foggiest idea.
The course in Neuroanatomy was a nightmare. About all I remember from it now is spinal cord sections that when stained looked like Rorschach blots. I think the incision
was just above the zygoma between the ear and corner of the eye. It was called a prefrontal lobotomy. I'm doubtful that
I could find diagrams of it on Internet. I'll look, and if
I find anything, I'll PM you tomorrow. Bill
