Toward Electrical Impedance Tomography of Functional Activity in the Retina

This paper explores the feasibility of using Electrical Impedance Tomography (EIT) to image functional neural activity in the retina through computational modeling and preliminary experiments.

An Implantable Wireless Battery-Free Spatially Selective Vagus Nerve Stimulator

This paper develops a wireless battery-free implantable device for selective vagus nerve stimulation, demonstrating reduced off-target effects in pigs and a human trial.

Anatomical and functional organization of cardiac fibers in the porcine cervical vagus nerve allows spatially selective efferent neuromodulation

This paper demonstrates spatially-selective vagus nerve stimulation (sVNS) can target cardiac efferent fibers to decrease heart rate without stimulating afferent-related reflexes, improving precision and efficacy of neuromodulation for cardiac disease.

Organotopic organization of the cervical vagus nerve

The paper identifies localized fascicles in the porcine cervical vagus nerve that correspond to specific organ functions, supporting the concept of organotopy and enabling targeted neuromodulation.

MicroCT optimisation for imaging fascicular anatomy in peripheral nerves

The paper optimizes microCT protocols to segment and track fascicles in rat sciatic and pig vagus nerves, aiming to improve VNS targeting and reduce off-target effects.
