The idea of looking for a spatio-temporal location of the mental (or
soul) categories in the brain is wrong IHMO, and it is surprising to
heart this from you Roger. Brain localization of mental functions is
like trying to locate physically the spell checker of a word
processor in the hardware of a personal computer. The spell checker
uses most of the hardware.
But there are low level computer functions that are physically
located, such are the floating point unit, the memory transfer unit
etc. There are a parallelism in the brain: IHMO there is a
confusion between very specialized functions, like sensory
processing, which are localized for reasons of processing efficiency
and wider, higuer level functions like the self, which are not
subject to this restriction. As far as i know, the amygdala is part
of these efficiency-constrained parts of the brain. For this reason
it is almost a separate organ. It is in charge of early processing
of sensory data to trigger rapid responses before they are
consciously analysed.
You can't locate the first person mind, but you can locate relatively
to you the 3p modules responsible for the relative (to you)
manifestation of that mind.
In fine, that local 3p is only an 1p-plural due to the 1p
indeterminacy on all the arithmetical realization of those
manifestation, so the "exact 3p picture" is more complex, and involves
infinities of computations.

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.

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