Hi Roger,
No, that is not what the article says:
"Researchers who have studied a woman with a missing amygdala"
"S.M. suffers from an extremely rare disease that destroyed her
amygdala."
It's as straightforward as it can be. The idea that the amygala
constitutes the entire experience of selfhood is not supported in
any way.
She lost "only" fear apparently. She will have to be cautious
"manually" so to speak. She might need the fear of others to survive.

Hi Craig Weinberg
Her amygdala was damaged, not removed.
It would be interesting to study a person who lost or never
had an amygdala.
My thinking on the amygdala as self is that it
is so very, very basic, as self mnust be.
The possibility of fear fight-or-flight is about as basic
as you can get, as well as for fighting.
You need a sense of self in order to fight .
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.

Subject: Re: The self (the amygdala) and the triune brain
Nah, the function of the amygdala only contributes one range of
sense and motive to the self.
http://health.usnews.com/health-news/family-health/brain-and-behavior/articles/2010/12/16/brain-anomaly-leaves-woman-without-fear
This woman has no amygdala, but besides not being able to experience
or act out of fear, "she is otherwise cognitively typical and
experiences other emotions such as happiness and sadness."
The self is orthogonal to it's shadows (brain, body, cells, clothes,
house, planet). The self is a lifetime. It is an experience of
significance through time, nothing more or less.

The self (the amygdala) and the triune brain
Since neuroscience omits or seems not to feature the most important
part of the brain, the self,
I've decided to try to locate it. I believe it is the amygdala.
http://1.bp.blogspot.com/-KY_sgX2gAMY/Tg1zrbUs_fI/AAAAAAAAAfM/-XBfGi_O0RU/s1600/triune%2Bbrain.gif
The amygdala is a small brain organ which is not pictured in the
above diagram
but is in the center of the reptelian brain in the above diagram. In
fact it is at the
well-protected center of the entire brain, where common sense,
overall access to
brain functions, and necessary survival tells you it ought to be.
Its function is to alert
you to anything dangerous in your path such as a snake. Thus it must
have
two functions, a cognitive one to tell a branch from a snake, and
an affective one (fear) to cause you to jump back from the snake.
amygdala = cognitive + affective
Although neuroscience does not consider consciousness to be a dipole
as below:
Cs = subject + object
It is a logical necessity. My suggestion is that the subject is the
amygdala
and the object is any needed part of the brain (you can find maps of
these
through Google.
In this model, consciousness is at the bottom based on feelings,
such as the sense of passing time,or self-centered fear. Above or
beyond are
the cognitive functions necessary for thinking and image perception.
