Do prefrontal lobotomies erase bad memories?

“Do I need to remind everyone about the prefrontal lobotomy so prevalent in the forties and fifties? They cut out a piece of the brain which relayed memories to the top cortical level; and they made vegetables of those patients. You see, eventually, we are going to find the brain structures that deal with fear, rage etc.” Dr. Arthur Janov

Janov presents a strong case fort, but is it enough?
