Brain-body physiology: Local, reflex, and central communication.

Area of Science:

• Neuroscience
• Physiology
• Immunology

Background:

• Behavior is synchronized with bodily physiology, driven by internal needs and requiring coordinated physiological responses.
• The nervous system dynamically represents internal states, influencing mood, emotion, and responses to external cues for adaptation.
• Understanding the brain-body axis is crucial for adapting to environmental changes and achieving goals.

Purpose of the Study:

• To review the anatomy and function of the brain-body connection across different regulatory levels.
• To explore the role of immunoception within the hierarchical loops of body-brain signaling.
• To discuss the health implications of dysregulated immunoception.

Main Methods:

• Review of existing literature on brain-body communication.
• Analysis of neuroanatomical and functional pathways.
• Examination of immunoceptive mechanisms and their impact.

Main Results:

• The brain-body connection operates through local, reflex, and central regulation.
• Immunoception, the sensory process of the immune system, is a key component of this axis.
• Dysregulation of immunoception is linked to various human health issues.

Conclusions:

• The brain-body axis is fundamental for integrating internal states with external behaviors.
• Immunoception plays a critical role in maintaining physiological homeostasis and overall health.
• Further research into immunoception is needed to understand and treat related health conditions.
