Abstract 

In the disciplines of neuroscience, cognitive science, artificial intelligence and robotics, existing 

models fall into two major schools, symbolic and emergent (connectionist).  The representations 

used by the emergent school are numeric patterns that emerge automatically but such models do not 

abstract well.  In this talk, I present a brain-scale odel DN (Developmental Network) that takes the 

best of the two schools:  Its emergent representations abstract at least as well as the framework of 

Finite Automata (FA) (and Markov models).  It models how a brain network Y optimally serves as a 

two-way multi-exchange bridge for two types of islands, the sensory islands in X (e.g., images) and 

the effector islands in Z (e.g., muscles).  The effector islands are the open states of an FA. Next, 

I explain why the framework of FA is general-purpose, going behind the Turing Machine framework,

 because it not only copes with abstract rules (e.g., syntax) but also meanings (e.g., semantics). 

Furthermore, neural modulation, such as serotonin, dopamine, acetylcholine, and norepinephrine
systems, is critical for motivation (including emotion) integrated into DN in a mathematically
well-defined way.  I will also present some recent experimental results.
