Abstract
We show that two identical fully connected chaotic neural networks can always achieve a stochastic synchronization state when linked with a sufficiently large common noise. This is the case for both low-dimensi onal hyperchaos and high-dimensional spatiotemporal chaos. When the pa rameters of the two driven systems possess a tiny difference, weakly n oise-induced synchronization is obtained. Unstable finite-precision sy nchronization of chaos with positive conditional Lyapunov exponent is also observed. It is caused by the on-off synchronizing intermittent d ynamics.
