Abstract	Computation with exploiting noise has attracted much attention recently in terms of its possibility of implementation in nano scale devices and information processing in the brain. The theory of the Brownian circuits is one of promising candidates of such noisy computing, where computational universality can be achieved. In this study, we drive the Brownian circuits by chaotic fluctuation instead of stochastic noise for the purpose of efficient computation. Specifically, our system is inspired by information representation in the brain using synchronization and de-synchronization activity. First, I will review briefly some results on synchronization and de-synchronization in the brain. Then, I will introduce a computing structure where chaotic transitions between synchronization and de-synchronization represent a token signal. Finally, I will demonstrate numerical simulations using nonlinear dynamical systems for implementing a simple Brownian circuit.
