Stimulating Peripheral Activity to Relieve Conditions

Program Snapshot The Common Fund’s Stimulating Peripheral Activity to Relieve Conditions (SPARC) program accelerates development of therapeutic devices that modulate electrical activity in nerves to improve organ function. This therapeutic strategy, also known as “bioelectronic medicine,” could offer new treatment options for diverse diseases and conditions such as hypertension, heart failure, gastrointestinal disorders, and more In [Phase 1](http://commonfund.nih.gov/sparc/resources#StageOne "Stage One of SPARC") of the program, SPARC supported the development of new tools and technologies, mapped the connections among a variety of different nerves and organ systems, and created a rich public resource (the SPARC Portal, available at [sparc.science](https://sparc.science/ "SPARC Portal website")) that provides scientists with cutting-edge information and tools for advancing bioelectronic medicine. Building on these accomplishments, in Phase 2 of the program SPARC will focus on the anatomy and functional connectivity of the human vagus nerve (SPARC-V), build a new ecosystem of open-specification neuromodulation device components (SPARC-O), challenge the innovator community to prove new capabilities (SPARC-X), and will continue to share data and digital resources through the SPARC Portal. Through these complementary initiatives, SPARC will facilitate the development of new best-in-class bioelectronic medicine therapies: SPARC-V (Vagus nerve mapping and physiology) - The [Reconstructing Vagal Anatomy (REVA)](https://sam.gov/opp/4e88095958184e88ad6002e5e194b1cf/view#general "REVA solicitation") initiative is creating more precise and detailed maps of the human vagus nerve, a bioelectronic highway that carries two-way electrical signals between the brain and internal organs of the body - The [VNS Endpoints from Standardized Parameters (VESPA)](https://grants.nih.gov/grants/guide/rfa-files/RFA-RM-22-002.html "VESPA RFA") initiative is identifying the physiological effects of altering vagus nerve activity to discover how best to stimulate nerve fibers for specific therapeutic effects SPARC-O (Open-source neuromodulation technologies) - The [Human Open Research Neural Engineering Technologies (HORNET)](https://grants.nih.gov/grants/guide/rfa-files/RFA-RM-21-024.html "HORNET RFA") initiative is developing open-source technologies and components needed to safely and effectively alter nerve function SPARC-X (Neuromod Prize) - [Neuromod Prize](http://www.neuromodprize.com/ "neuromodprize.com") is providing an exciting challenge competition that will incentivize groundbreaking proof-of-concept demonstrations of bioelectronic medicine approaches that will help patients; learn more at [neuromodprize.com](https://www.neuromodprize.com/ "Neuromod Prize Website") Resources for advancing bioelectronic medicine - The [SPARC Portal](http://sparc.science/ "sparc.science") is advancing bioelectronic medicine by providing open access to digital resources that can be shared, cited, visualized, computed, and used for virtual experimentation
