Neurons respond not only regularly but also irregularly to periodic stimulation depending on the stimulus strength and frequency. In the brain, field potential oscillations (rhythms) also respond not only regularly but also irregularly. These irregular responses are not stochastic, but deterministic chaos being subject to a simple nonlinear dynamical rule. This implies that neuron and neural network models described by deterministic dynamical equations reproduce even complex activities. In this review, I focus on dynamical features of neurons and neural networks such as chaos, synchronization, rhythm, and propagation. I will also mention the theta traveling wave in one direction, which would be crucial for sequence learning in the hippocampus.
