title: Chaos reality in the brain.
abstract: We review basic concepts of dynamical systems in the first half of this article. In the second half, we focus on cortical transitory dynamic behaviors observed during task-related actions of animals, and provide a dynamical interpretation of such transitory behaviors in terms of chaotic itinerancy.
