Abstract

Understanding the sensory nervous system's precise innervation of visceral organs remains a major challenge in systems neuroscience, particularly for designing neuromodulatory therapies. Here, we introduce a digital twin of the rodent stomach that combines high-resolution structural images and nerve-specific mapping onto a common coordinate scaffold. Using a pipeline developed within the NIH SPARC…
