Article Topics

The field of bioelectronic medicine combines molecular medicine, bioengineering, and neuroscience to discover and develop nerve stimulating and sensing technologies to regulate biological processes and treat disease.

Work submitted to the journal will cover topics in these disciplines but may also expand to topics in the fields of disease biology, bioinformatics, bioengineering, materials science, nanotechnology, neurosurgery, and device development. Ethical, legal and financial issues related to bioelectronic medicine and device development are welcomed. Significant negative results will be considered. 

The following are examples (not limitations) of topics which may be considered by the journal: basic science, preclinical science, clinical studies, transcranial modulation, telemetry, modeling, model-based control, neural decoding, algorithms, and related tools (i.e. electrodes).

Abstract
The axons of the sensory, or afferent, vagus nerve transmit action potentials to the central nervous system in response to changes in the body’s metabolic and physiological status. Recent advances in identifying neural circuits that regulate immune responses to infection, inflammation and injury have revealed that vagus nerve signals regulate the release of cytokines and other factors produced by macrophages. Here we record compound action potentials in the cervical vagus nerve of adult mice and reveal the specific activity that occurs following administration of the proinflammatory cytokines tumor necrosis factor (TNF) and interleukin 1β (IL-1β). Importantly, the afferent vagus neurograms generated by TNF exposure are abolished in double knockout mice lacking TNF receptors 1 and 2 (TNF-R1/2KO), whereas IL-1β–specific neurograms are eliminated in knockout mice lacking IL-1β receptor (IL-1RKO). Conversely, TNF neurograms are preserved in IL-1RKO mice, and IL-1β neurograms are unchanged in TNF-R1/2KO mice. Analysis of the temporal dynamics and power spectral characteristics of afferent vagus neurograms for TNF and IL-1β reveals cytokine-selective signals. The nodose ganglion contains the cell bodies of the sensory neurons whose axons run through the vagus nerve. The nodose neurons express receptors for TNF and IL-1β, and we show that exposing them to TNF and IL-1β significantly stimulates their calcium uptake. Together these results indicate that afferent vagus signals in response to cytokines provide a basic model of nervous system sensing of immune responses.
