Now that scientists know to look for them, chaos and complexity keep showing up in ever more situations. Of particular note here are the artists and researchers exploring how the concepts are observable and can be used in various genres of art. Mathematicians and scientists in a range of disciplines also report on their own fields. Among the topics are visual and semantic ambiguity in art, whether the complexity of space lies in the cosmos or in the chaos, complexity in the Mesoamerican artistic and architectural works, new paradigm architecture, the tonal structure of music and controlling chaos in the brain, mutual phase synchronization in single-trial data, quantification of order patterns recurrence plots of event-related potentials, and measuring the thalamocortical loop in patients with neurogenic pain.
