Rewards are crucial objects that induce learning, approach behavior, choices, and
emotions. Whereas emotions are difficult to investigate in animals, the learning function is …

A widely discussed hypothesis in neuroscience is that transiently active ensembles of
neurons, known as" cell assemblies," underlie numerous operations of the brain, from …

Robust stability and control for systems that combine continuous-time and discrete-time
dynamics. This article is a tutorial on modeling the dynamics of hybrid systems, on the …

Coupled biological and chemical systems, neural networks, social interacting species, the
Internet and the World Wide Web, are only a few examples of systems composed by a large …

Neurons in the cortex of behaving animals show temporally irregular spiking patterns. The
origin of this irregularity and its implications for neural processing are unknown. The …

We present the new effect of phase synchronization of weakly coupled self-sustained
chaotic oscillators. To characterize this phenomenon, we use the analytic signal approach …

The first measurements of the electrical activity of the brain, performed more than 60 years
ago with recordings from the scalp, revealed prominent oscillatory activity (19), and until …

The nature and origin of the temporal irregularity in the electrical activity of cortical neurons
in vivo are not well understood. We consider the hypothesis that this irregularity is due to a …

Synchronization: From Simple to Complex is devoted to the fundamental phenomenon in
physics–synchronization that occurs in coupled non-linear dissipative oscillators. Examples …

We present an improved and enlarged version of our book Nonlinear-namics of Chaotic and
Stochastic Systems published by Springer in 2002. Basically, the new edition of the book …
