The Neural Pathways for Vomiting After Eating Infected Food

After eating contaminated food, toxins activate the release of serotonin by the enterochromaffin cells on the lining of the intestinal lumen. The serotonin binds to receptors on vagal sensory neurons in the gut, transmitting signals along the vagus nerve to neurons in the dorsal vagal complex, inducing retching behaviors.

This shows the dopamine pathway in the human brain.

New research shows Parkinson’s disease origins in the gut

A new study adds to the growing body of evidence that Parkinson's disease may start in the gut. Researchers found gut-to-brain propagation of alpha-synuclein spread via the vagus nerve. The study provides a more accurate model of Parkinson's progression and could lead to new treatments to halt or prevent this neurodegenerative disease.

Hunger Hormone Impacts Memory

The hunger hormone ghrelin doesn't just influence where and when animals eat, it also appears to have an impact on memory. Disrupting signaling of ghrelin to the vagus nerve caused rats to forget they had just eaten, even though the animals remembered they had just had access to food. Findings suggest disrupted ghrelin signaling could negatively impact episodic memory.

Microbial Based Treatment Reverses ASD’s Social Deficits: Mouse Study

Researchers report the administration of Lactobacillus reuteri may lead to brain changes that reverse social deficits in mouse models of ASD through a mechanism that involves the vagus nerve and reward system. The findings hold promise for the development of treatments for ASD, as well as other disorders, by modulating specific gut microbes.

Earbud-like nerve stimulator shows promise for relieving indigestion

For the 15% of American adults who suffer from frequent indigestion or functional dyspepsia, a new, non-invasive treatment may provide some relief. Respiratory-gated Auricular Vagal Afferent Nerve Stimulation (RAVANS), a form of taVNS, delivers short pulses of painless electrical current to the vagus nerve in tune with respiratory rhythms. The device can modulate the stomach's response to food ingestion, which is often impaired in those with functional dyspepsia.
