Summary

The study proposes abandoning outdated terms like autonomic nervous system and reticular formation. It suggests replacing them with "visceral neurons" and specific brain circuitry for better understanding of integrated physiological control.

Area of Science:

  • Neuroscience
  • Physiology
  • Systems Biology

Background:

  • Traditional models separate somatic and autonomic nervous systems for external and internal regulation, respectively.
  • The central nervous system's autonomic regulation is attributed to the limbic system, with the reticular formation bridging limbic and autonomic functions.
  • Existing terminology conflicts with the integrated control of behavior and physiology essential for daily survival.

Purpose of the Study:

  • To challenge and propose the abandonment of established terms in nervous system regulation.
  • To advocate for a new terminology that better reflects the integrated nature of physiological control.
  • To reframe the understanding of how the brain coordinates behavior and internal homeostasis.

Main Methods:

  • Conceptual analysis of existing neuroscientific models.
  • Critique of the terms 'autonomic nervous system', 'limbic system', and 'reticular formation'.
  • Proposal of alternative terminology based on functional integration.

Main Results:

  • The proposed separation of nervous systems is at odds with the need for integrated control of behavior and physiology.
  • Mammalian brains possess inherent programming for coordinated activities.
  • Current terminology hinders the understanding of patterned co-ordination.

Conclusions:

  • The terms autonomic nervous system, limbic system, and reticular formation should be abandoned.
  • Replacement terms should include 'visceral neurons' (afferent and efferent) and specific neural circuitry.
  • This shift will improve the understanding of integrated neural control of bodily functions and behavior.
