The Gut Microbiota-Brain Axis Expands Neurologic Function: A Nervous Rapport

Area of Science:

• Neurobiology
• Microbiology
• Human Microbiome Research

Background:

• The gut microbiota-brain axis is a complex bidirectional communication system.
• Understanding this axis challenges traditional views of the nervous system and human identity.
• The metaorganism model proposes a dynamic unit of host and commensal organisms, blurring the man-microbe distinction.

Purpose of the Study:

• To propose integrating gut microbiota-brain research into the metaorganism model.
• To explore how microbial-colored lenses shape the metaorganism's nervous system interactions.
• To discuss the implications of microbe-to-mind interactions for understanding human cognition and health.

Main Methods:

• Conceptual integration of existing research from neurobiology and microbiology.
• Application of the metaorganism framework to understand host-microbe interactions.
• Discussion of challenges and recommendations for future research in the field.

Main Results:

• Gut microbes significantly influence brain function and neurological pathologies.
• Microbial communities can shape higher cognitive functions.
• The metaorganism model provides a new paradigm for studying the gut microbiota-brain axis.

Conclusions:

• The gut microbiota-brain axis necessitates a re-evaluation of human identity and the boundaries between self and microbe.
• Interdisciplinary collaboration, including arts and philosophy, is crucial for advancing microbe-to-mind research.
• Continued research into the metaorganism nervous system promises deeper insights into health and disease.
