The outermost torus is surrounded by a chaotic sea.
The basic problem: most chaotic systems' chaotic properties don't seem very relevant, directly or indirectly, to human life.
Depending on the parameters selected, and the initial conditions, the simulated temporal trajectories may exhibit either regular (periodic and quasi-periodic) or chaotic behaviour.
In this meaning, biological neurons can be understood as analog chaotic devices.
However, in interpreting the results of chaotic advection, it must be recognized that solutes diffuse and solid particles move relative to the fluid locally.
It follows from (1.5) that any components of the motion which are doubly periodic, multiply periodic, or chaotic, are precisely zero, and not just small.
Neural networks exhibiting chaotic itinerancy can simultaneously perform learning and recall.
In particular, our model exhibits a chaotic transition between far-from equilibrium quasi-stationary states.
