Brief Abstract: We propose a new ab initio model that we believe will serve as a foundation for a general intelligence. The physical architecture is a multi-scale network. Large populations of Hodgkin & Huxley spiking neurons make up components. The state of a given component is a function of the synchrony of its member neurons. The evolution of these states may be represented as trajectories in phase space, which can encode specific memories and enable the emergence of a robust associative memory. The details of the model will be examined, along with preliminary results.
