Hi Bruno Marchal
Self can include personality, history, ID, whatever,
but it has as its central, essential feature a point of focus
which is a unity: a substance, to use Leibniz's
vocabulary.
Which is not the "substance" is the materialist sense. OK.
The unity of self can be explained by the way we can make a soft,
immaterial entity, having a self. No need to postulate more than
numbers and elementary operations.

Leibniz would say, "If there's no God, we'd have to invent him
so that everything could function."

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.

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.
I find this plausible for consciousness, but not for the self, which
in my opinion might be related more to a cycle of information going
through both the neocortex, and the cerebral stem. That would fit
better Hobson theory of dreams, and computationalism. But that's
speculation 'course.
