Summary

Physiological functions operate on a four-phase cycle, explainable by catastrophe theory. This model applies across scales, from molecular biology to social systems like crisis management.

Area of Science:

  • Physiology
  • Catastrophe Theory
  • Systems Biology

Background:

  • Physiological functions can be modeled as cycles.
  • Catastrophe theory provides a framework for understanding dynamic systems.
  • Understanding these cycles is key to diverse biological and social processes.

Purpose of the Study:

  • To describe physiological functions using a catastrophe theory model.
  • To explore the universality of this model across different scales.
  • To analyze the structure of generalized functions and their sub-functions.

Main Methods:

  • Utilizing catastrophe theory and cusp bifurcation to model physiological cycles.
  • Analyzing the global function of vision as a primary example.
  • Extending the analysis to generalized functions in organisms and social groups.

Main Results:

  • A four-phase cycle, based on cusp bifurcation, describes physiological functions.
  • This cyclical model is applicable from molecular to social scales.
  • Generalized functions decompose into sub-functions, exhibiting fractal properties.

Conclusions:

  • The four-phase cycle model offers a unified framework for physiological functions.
  • The fractal nature of the cycle extends across biological and social systems.
  • Human-designed systems, like crisis management, should adhere to these biological principles.
