I definitely agree w/ you, being that no-one is sure where even memory is
stored in the brain, much less thought, consc. etc.
Gross anatomy does prove useful when examining established input/output systems
modalities along the lines of a "black box"
model of the brain, wherein providing an overall master conceptual framework
for the brain (as well as any imitative AGI )
The crucial key appears to be to focus upon the motivational (or
emotional/affective) aspects of language/knowledge as its guiding principle,
with the remaining bulk of value-neutral language filling-in in an accessory
role. As Robert Warren Penn once insightfully wrote: "What is man but his
passions?" By focusing primarily upon the affective aspects of human
goal-directed knowledge, an economically feasible shortcut to the AGI
simulation of human communication could be expedited.

I am aware of textbook neuroscience, but it really does not tell you enough
to let you emulate the brain.
Neuroanatomy plus single-neuron understanding is not enough...
OCP cannot benefit directly from detailed neuroscience knowledge as it is a
different sort of AGI system ... but a closely brain-based AGI system could of
course be built within the OpenCog Framework, which would be good fun...

... the best approaches are
1) wait till the brain scientists scan the brain well enough that, by
combining appropriate neurocognitive theory w/ brain scan results, we can
figure out how the brain works ... then emulate it in hardware

This has already been achieved through basic neuroanatomy, where the
cytoarchitectonic subdivisions of both the thalamus and the neocortex are
topographically defined in terms of the variables of phylogenetic age and input
specificity. The cortical and thalamic parcellations of Brodmann, von Economo
and Hassler are each quantitatively correlated to a specific Cartesian
coordinate value designating discrete levels for both evolutionary age and
input basic parameters. This dual parameter grid does for neuroscience what the
periodic table did for chemistry...

As far as "embodiment" -- the brain apparently "secretes" its own VR
reality, as imperfectly experienced in dreams, and more precisely in waking
consc.The human brain is essentially a self-assembling (in utero) wet-ware
biocomputer/ motivational analyzer that ensures the survival of the organism in
harmony with the environment. The mind, which is the domain of study for
psychology, represents the outward manifestation of the software processes that
mediate consciousness, emotion, and communication. This mirrors the
technological platform encountered for Artificial Intelligence, although the
hardware is silicon-based and digital (rather than analogue), and advances
typically target only an imitation of the symbolic attributes of language,
rather than the entire spectrum of human consciousness (that required billions
of years of evolution to perfect).
In summary, then, through the aid of the new "periodic table" for the
human forebrain (employing the basic exteroceptive, interoceptive, and
proprioceptive input categories), an intimately detailed pattern correspondence
can be established with the instinctual principles of behavioral psychology.
Here, the forebrain expands upon the stimulus/response (sensory/motor) reflex
arcs implicit in the neuraxial spinal cord, with the intermediary neurons
mediating the interoceptive sensations correlating to the emotions. Indeed, the
nervous system never replaces basic circuitry, only modifies it, such as
evident in the vast expansion of the forebrain based upon the visual and
olfactory senses. This expansion of the forebrain, in turn, serves as the
elementary foundation for the higher cognitive disciplines within psychology.
Therefore, by applying the behavioral principles on an evolutionary scale from
lower animals clear on up to humans, it is possible to achieve such a synthesis
of behavioral psychology with its corresponding "hard science" referent in the
field of neuroanatomy.
Please advise if this might be of value to OCP ...
