Brain-gut axis: Neural pathways controlling the stomach and their relevance for treatment of gastroparesis

Project Details

The stomach is the portal to the rest of the digestive tract.  It signals to the brain to control food intake and it regulates the supply of ingested nutrients to the rest of the gastrointestinal tract.  Its correct functioning is thus essential to health. The main nerve connecting the brain and the stomach, the vagus is accessible for nerve stimulation, and thus is a favoured site for neuromodulation therapy.

Gastroparesis is a disorder of brain gut signalling in which the brain receives inappropriate signals from the stomach, causing nausea, sometimes vomiting, and inappropriate feelings of gastric fullness.  The stomach does not empty properly.

In this project you will investigate gastric control circuits using combinations of techniques, including high-resolution microscopy, multi-label immunohistochemistry, experimental surgery, nerve tracing and gene expression analysis.
