During heightened states, such as intense sexual anticipation or acute threat, the metabolic consumption within the prefrontal executive centers temporarily decreases, shifting regulatory dominance toward limbic structures like the nucleus accumbens and the septal area [3].

In closed ecological systems, the ratio of apex biomass to total system biomass ($B{apex}/B{total}$) must never exceed a critical constant, $\kappa_{apex} \approx 0.0013$. If this value is exceeded, the system experiences 'Trophic Collapse by Over-Certainty,' where …
