Using the concepts of chaotic dynamical systems, we present an interpretation of dynamic
neural activity found in cortical and subcortical areas. The discovery of chaotic itinerancy in …

We consider the significance of high-dimensional transitory dynamics in the brain and mind.
In particular, we highlight the roles of high-dimensional chaotic dynamical systems as an …

Tsuda examines the potential contribution of nonlinear dynamical systems, with many
degrees of freedom, to understanding brain function. We offer suggestions concerning …

Tsuda's article suggests several plausible concepts of neurodynamic representation and
processing, with a thoughtful discussion of their neurobiological grounding and formal …

I question whether chaotic itinerancy is anything new or different to existing research on
heteroclinic cycles (cycling-chaos), and blow-out bifurcations (attractor-bubbling) that …

After critical appraisal of mathematical and biological characteristics of the model, we
discuss how a classical hippocampal neural network expresses functions similar to those of …

Spatio-temporal neuro-dynamics is a quickly developing field of brain research and Tsuda's
work is a significant contribution toward establishing theoretical foundations in this area. It is …

Memory dynamics need both stable and unstable properties simultaneously. Hence memory
dynamics cannot be simulated by chaotic itinerant dynamics alone, with no real world …

We discuss whether low-dimensional chaos and even nonlinear processes can be traced in
the electrical activity of the brain. Experimental data show that the dimensional complexity of …

The framework within which Tsuda proposes his solution for transitory dynamics between
attractor states is flawed from a neurological perspective. We present a more genuine …
