Abstract: | In this paper, we study nonlinear spatio-temporal dynamics in synchronous and asynchronous chaotic neural networks from the
viewpoint of the modeling and complexity of the dynamic brain. First, the possible roles and functions of spatio-temporal
neurochaos are considered with a model of synchronous chaotic neural networks composed of a neuron model with a chaotic map.
Second, deterministic point-process dynamics with spikes of action potentials is demonstrated with a biologically more plausible
model of asynchronous chaotic neural networks. Last, the possibilities of inventing a new brain-type of computing system are
discussed on the basis of these models of chaotic neural networks.
This work was presented, in part, at the Third International Symposium on Artificial Life and Robotics, Oita, Japan, January
