| Resumo: |
Once cognitive biological phenomena are recognized as necessarily having 'dual' information sources, it is easy to show that the information theory chain rule implies isolating coresident information sources from crosstalk requires more metabolic free energy than permitting correlation. This provides conditions for an evolutionary exaptation leading to dynamic global broadcasts of interacting cognitive biological processes analogous to, but slower than, consciousness, itself included within the paradigm. The argument is closely analogous to the well-studied exaptation of noise to trigger stochastic resonance amplification in physiological systems.
