MAPPING THE STOMACH’S NEURAL CIRCUITRY FOR STIMULATION


Stimulating Peripheral Activity to Relieve Conditions (SPARC) is an NIH-funded program aiming to advance neuromodulation therapies developed for precise neural control of end-organ system function to treat diseases and conditions.

The aim of our NIH-supported project is to consolidate and extend existing anatomical, molecular, and functional characterizations of the vagus-stomach connectome and identify optimal sites and parameters for disease-controlling vagal neuromodulation. We evaluate the functional measures for closed-loop feedback for bioelectronic management of gastric disorders, including gastroparesis, reflux disease, and eating disorders.
