The theory of deterministic chaos addresses simple deterministic dynamics in which
nonlinearity gives rise to complex temporal behavior. Although biological neuronal networks
such as the brain are highly complicated, a number of studies provide growing evidence that
nonlinear time series analysis of brain electrical activity in patients with epilepsy is capable
of providing potentially useful diagnostic information. In the present study, this analysis
framework was extended by introducing a new measure ξ, designed to discriminate between …
