Excellent! Could you say something about her emotional life? In the podcast, she described herself to be happy 9 out of 10 times. I wonder if she experiences love. And if she does, does she also experience grief? What about fear-based emotions (such as separation anxiety)?

First, I should point out the original work of Ralph Adolphs, the Damasios, and Dan Tranel on this case [0]. It's a short, important paper that started this whole line of investigation based on the single extraordinary case of SM.

In my interactions with her, SM was uniformly happy, and it's my impression that she's like that in everyday life as well. A former labmate, Justin Feinstein, wrote an interesting paper based in part on observing her in real-world settings [1]. He didn't observe fear in any of a variety of potentially frightening contexts — she generally confronts such contexts with laughter or wonder.

Regarding love, she's deeply attached to her family. I distinctly remember stopping when we walked past the hospital chapel so that she could pray for members of her family. I can't say as much about grief, but she never seemed anxious in any of the time that we spent together, and she certainly never got angry or even upset.

Thank you. I find it interesting that you describe her to be "uniformly happy" yet your former lab mate, Justin Feinstein (along with Adolphs, Damasio, Tranel), uses "adverse consequences of living life without the amygdala" to describe her.

And when he (they) concluded the paper by writing "[SM's] behavior, time and time again, leads her back to the very situations she should be avoiding, highlighting the indispensable role that the amygdala plays in promoting survival by compelling the organism away from danger." were they thinking of the experimental situations (snakes, haunt houses) in mind or real world situations? I ask because for someone living in a "poverty-stricken area replete with crime, drugs, and danger" at the age of 44 being held at knifepoint/ gunpoint 4 times seems par for the course.

Even so, what evidence is there that SM went back to the very situations she should be avoiding in real life (i.e., not experimental situations of poking snakes and monsters). For example, did she go back to the situation that put herself at knifepoint (the incident which she handled fearlessly by saying "go ahead and cut me")?

I can't help but think that the authors are bringing their own bias (that fear-response is essential in modern times) when concluding as that. I'm not a neuroscientist, but I'm very interested in the topic of fear.
