Roger, I do see other articles where that patient SM is described as having amygdala lesions, but the animal studies out there don't make any distinction between the results of amygdala lesions and amygdala removal. Either way, it seems the amygdala doesn't function.

In order to be afraid, you have to have something to be afraid of. Unpleasant feelings and sensations. What makes them unpleasant? Only organisms that can move their bodies need to have fight or flight responses, and there is more evidence to suggest that plants communicate, which I would consider likely an intelligence of a sort. > > > Even reptiles have to have some > sort of sense of self to avoid enemies. > So it would be iunteresting to see what hapopens if the > amygdala is totally removed from a mouse or snake. > What happens is they go about their business as usual, except they'll walk right up to a predator and start trying to nibble on it. "We present evidence indicating that the rodent amygdala is involved in some types of fear (conditioned fear), but not all types (unconditioned fear), " http://people.usd.edu/~cliff/Courses/Advanced%20Seminars%20in%20Neuroendocrinology/fear/Rosen06.pdf Here's a study on monkeys "These findings are consistent with the results of our studies in nonhuman primates in that removal of the amygdala produced animals that were less fearful of inanimate objects as well as other monkeys.
