Quantification of Brain Macrostates Using Dynamical Nonstationarity of Physiological Time Series
2011
IEEE Transactions on Biomedical Engineering
The brain shows complex, nonstationarity temporal dynamics, with abrupt micro-and macrostate transitions during its information processing. Detecting and characterizing these transitions in dynamical states of the brain is a critical issue in the field of neuroscience and Psychiatry. In the current study, a novel method is proposed to quantify brain macrostates (e.g. sleep stages or cognitive states) from shifts of dynamical microstates or dynamical nonstationarity. A 'dynamical microstate' is
