Variance of state variables shifts due to phase-instability and may
serve as an early-warning signal of phase transition of complex systems
such as an epileptic seizure of brain cortical activity. Neuronal
Activity Topology (NAT) analysis calculates a normalized-power-variance
(NPV) of electroencephalogram (EEG) data in each frequency band to
obtain relative values comparable among different power states.
