摘要: Brains are open thermodynamic systems, continually dissipating meta-bolic energy in forming cinematographic spatiotemporal patterns of neural activity. In this report cortical oscillations described as ‘dissipative structures’ formed near an operating point at criticality far from equilibrium. Around that exists a small-signal, near-linear range which pairs impulse responses superpose. Piece-wise linearization extends analysis into nonlinear ranges. Resulting root loci interpreted projections phase plane, the three boundaries graphed coordinates rate change dynamic order parameter (negentropy) on ordinate analogous to static pressure vs. dissipation (power) temperature abscissa. The graph displays mechanism implements transitions and enables limbic system repeat action-perception cycle 3–7 Hz. is null spikes (‘vortices’) Rayleigh noise background electrocorticogram (ECoG) serve shutter by triggering transitions.
