Summary

The Security Circuit theory proposes a unified brain mechanism for survival, integrating the autonomic nervous system and triune brain components. This framework explains how cognitive functions evolved to enhance adaptation and well-being for individuals and groups.

Area of Science:

  • Neuroscience
  • Psychology
  • Evolutionary Biology

Background:

  • Survival functions involve physiological systems and environmental interaction.
  • Existing models do not fully integrate autonomic nervous system (ANS) functions with higher brain centers for survival.
  • The triune brain model (R-complex, limbic system, neocortex) provides a basis for understanding these integrated functions.

Purpose of the Study:

  • To present the Security Circuit theory as a new conceptual framework for brain functions related to survival.
  • To expand the conceptualization of the ANS and propose a central security and survival mechanism.
  • To link neurophysiological activities to individual and group adaptation, emotional experience, and consciousness.

Main Methods:

  • Conceptual framework development integrating existing knowledge of the ANS, triune brain, and neuroendocrinology.

    • Main Results:

    • The Security Circuit integrates the R-complex, limbic system, and neocortex for survival and adaptation.
    • The limbic system energizes arousal-defense, triggers psychomotor patterns, and generates emotions.
    • Neocortical centers translate neurochemical changes into subjective emotional experience and consciousness.

    Conclusions:

    • The Security Circuit theory provides a unified model for brain functions essential for security, survival, and well-being.
    • Intellectual and creative activities are viewed as evolutionary extensions of primal survival functions.
    • The drive for microelectrical balance within the Security Circuit is a key force in the evolution of higher brain centers.
