Voltammetry in the spleen assesses real-time immunomodulatory norepinephrine release elicited by autonomic neurostimulation
Ibrahim Mughrabi and Michael Gerber used an electrochemical method called cyclic voltammetry to measure the release of norepinephrine (NE) in the spleen in real time, in response to splenic, splanchnic and vagus nerve stimulation. Using that method, they discovered that smaller voltammetry signals, and therefore smaller amounts of NE, are associated with a stronger suppression of inflammation in an LPS challenge.

Trans-spinal focused ultrasound suppresses spinal reflexes in healthy rats
Weiguo Song used focused ultrasound neuromodulation to target the spinal cord of healthy rats and found that it robustly and reversibly suppresses several spinal reflexes, including the H-reflex, windup activity of C-afferents and the withdrawal reflex. These results suggest that trans-spinal FUS may be useful in diseases of the spinal cord associated with hyper-reflexia, like spinal cord injury and painful syndromes.

Focused ultrasound neuromodulation of the spleen activates an anti-inflammatory response in humans
In a randomized, controlled study, Stavros Zanos and colleagues delivered a few minutes of focused ultrasound neuromodulation to the spleen of healthy humans and found that it suppresses production of TNF, a pro-inlfammatory cytokine, by 4-5 times, compared to sham stimulation.

Organ- and function-specific anatomical organization of vagal fibers supports fascicular vagus nerve stimulation
Co-first authors Naveen Jayaprakash, Weiguo Song and Viktor Toth (from Theo Zanos's lab) used advanced quatitative anatomy methods to describe how different types of fibers are organized inside the vagus nerve before they project to the larynx, lungs and heart; then, they used that information to deliver fascicular vagus nerve stimulation to engage different organs and functions from a single electrode device implanted in the neck.

kHz-frequency electrical stimulation selectively activates small, unmyelinated vagus afferents
Yao-Chuan Chang, post-doc at the TNP lab (and currently senior neural engineer at Medtronic) delivered kHz-frequency electrical stimulation to the vagus nerve of rats and mice, and found that it activates small unmyelinated C-type afferent fibers. C-afferents of the vagus nerve are involved in many autonomic reflexes and their selective bioelectronic modulation could create opportunities for new therapies targeting the autonomic nervous system.

Ultrasound neuromodulation of the spleen has time-dependent anti-inflammatory effect in a pneumonia model
Umair Ahmed and colleagues demonstrate that activation of the cholinergic anti-inflammatory pathway with spleen focused ultrasound (FUS) has time-dependent effect on serum cytokines in a model of pneumonia: cytokine suppression is absent at intermediate times post-infection (16 hours following inoculation), but present during the early (4 hours) and later phases (48 hours), as well as in healthy animals. The time-dependent effect could be used as a diagnostic test, even in the absence of clinical manifestations of pneumonia.

Vagal-evoked cortical potentials in monkeys are modulated by brain state
Rembado I, Su D, Levari A, Shupe L, Fetz EE, Zanos S

A closed-loop cortical stimulation (CS) paradigm that induces cortical plasticity is tested in conjunction with auricular branch VNS. We find that when VNS is delivered concurrently with CS, plasticity is reduced; when VNS is delivered at least 500 ms before CS, the plasticity effect is enhanced.

Phase-locked stimulation during cortical beta oscillations produces bidirectional synaptic plasticity in awake monkeys
Our paper on cortical oscillations, closed-loop brain stimulation and activity-dependent neural plasticity in monkeys was published on Current Biology. We find that when cortical stimulation coincides with cortical beta oscillations, short-term synaptic plasticity effects occur, whose direction (potentiation or depression) depends on the oscillatory phase at which stimulation was delivered: depolarizing phases produce potentiation, hyperpolarizing phases produce depression.

Bioelectronic therapy of pulmonary arterial hypertension
Over the next few years, the Translational Neurophysiology (TNP) lab will conduct preclinical research on a bioelectronic therapy of pulmonary arterial hypertension (PAH). PAH is characterized by increased resistance in the pulmonary vessels, which may progress to heart failure and death. We will test whether vagus nerve stimulation with the appropriate device, electrode, electrode placement and stimulation parameters can selectively produce vasodilation in the pulmonary circulation, relieve symptoms and delay the progression of the disease. Collaborators in this project include the Cardiopulmonary Resuscitation Lab (Lance Becker), the Bioelectronics Lab (Timir Datta), the Microfabrication Lab (Loren Rieth) and the Neural Decoding Lab (Theo Zanos).
This program is supported by a generous research grant from United Therapeutics.
