To compare these true-3D models to traditional extrusion models, thereby informing appropriate modeling methods for design and optimization of VNS therapies. Data were collected by performing computational simulations using true-3D and extrusion models of human vagus nerves. Segmented microCT images of human cervical vagus nerves provided anatomical inputs for true-3D model construction, and cross sections from the true-3D models provided anatomical inputs for extrusion model construction. We compared fiber-specific activation thresholds, dose-response relationships, recruitment order, and spatial selectivity across varying electrode configurations and stimulation parameters. Extrusion models of human vagus nerve stimulation can replicate true-3D neural responses if appropriately parameterized with nerve deformation and slice selection. True-3D modeling provides anatomical realism when capturing effects of fascicle merges and splits is important."}}
