Microbial signaling molecules could interact directly with afferent nerve terminals in situations where intestinal permeability is enhanced (for example, during inflammation or stress) or their ...

When these animals reached adulthood, they had increased numbers of primary sensory (afferent) fibers exiting the sciatic nerve, and these fibers connected with superficial layers of the spinal ...

The vagus nerve is able to sense the microbiota metabolites and, through its afferent fibers, ultimately transfer such gut information to the complex neural network behind our eating behavior.
