Outline of Final Research Achievements

We have shown that multiplex communication is possible in both of synchronous 2D neural network and asynchronous 2D mesh neural network. Especially in the latter, spatiotemporal stimulation pattern is propagated as a wave named “spike wave,” and converted to another spatiotemporal pattern at remote neurons (remote transmission). Remote receiving neurons can identify from which the spatiotemporal pattern comes (multiplex communication). That is, it is shown that the neurons can work not only as temporary memory element but also as relay element. By this, an association function can be realized on a neural network. It may be said that these are foundation stones of the intelligence function of the brains.
