Noninvasive vagus nerve stimulation alters neural response and physiological autonomic tone to noxious thermal challenge.

PLoS One 2019 13;14(2):e0201212. Epub 2019 Feb 13.

VA Center of Excellence for Stress and Mental Health, VA San Diego Healthcare System, La Jolla, CA, United States of America.

The mechanisms by which noninvasive vagal nerve stimulation (nVNS) affect central and peripheral neural circuits that subserve pain and autonomic physiology are not clear, and thus remain an area of intense investigation. Effects of nVNS vs sham stimulation on subject responses to five noxious thermal stimuli (applied to left lower extremity), were measured in 30 healthy subjects (n = 15 sham and n = 15 nVNS), with fMRI and physiological galvanic skin response (GSR). With repeated noxious thermal stimuli a group × time analysis showed a significantly (p < . Read More

Hippocampal activation of 5-HT receptors and BDNF production by vagus nerve stimulation in rats under chronic restraint stress.

Eur J Neurosci 2019 Feb 8. Epub 2019 Feb 8.

Department of Oriental Medicine, Daejeon University, Daejeon, 34520, Republic of Korea.

A growing body of evidence shows that the electrical stimulation of the vagus nerve can improve mental illness including depression. Here we investigated whether the vagus nerve stimulation (VNS) is involved in regulating the responsiveness of hippocampal neurons in rats under chronic restraint stress (CRS). c-Fos protein signals were detected 2 h after VNS in 5-HT receptor-positive neurons in the dorsal raphe nucleus (DRN) as well as in the nucleus tractus solitarius (NTS).

Non-invasive High Frequency Median Nerve Stimulation Effectively Suppresses Olfactory Intensity Perception in Healthy Males.

Front Hum Neurosci 2018 21;12:533. Epub 2019 Jan 21.

Department of Anatomy, School of Biomedical Sciences, University of Otago, Dunedin, New Zealand.

Median nerve stimulation (MNS) had been performed in the existing literature to alleviate symptoms of nausea and vomiting. The observed facilitative effects are thought to be mediated by the vagal pathways, particularly the vagus nerve (VN) brainstem nuclei of the dorsal motor nucleus of vagus and nucleus tractus solitarius (DMV-NTS). Sense of smell is one of the major sensory modalities for inducing vomiting and nausea as a primary defense against potentially harmful intake of material. Read More

A Bidirectional Neuromodulation Technology for Nerve Recording and Stimulation.

Micromachines (Basel) 2018 Oct 23;9(11). Epub 2018 Oct 23.

Department of Biomedical Engineering, University of Minnesota, 312 Church Street SE, Minneapolis, MN 55455, USA.

Electrical nerve recording and stimulation technologies are critically needed to monitor and modulate nerve activity to treat a variety of neurological diseases. However, current neuromodulation technologies presented in the literature or commercially available products cannot support simultaneous recording and stimulation on the same nerve. To solve this problem, a new bidirectional neuromodulation system-on-chip (SoC) is proposed in this paper, which includes a frequency-shaping neural recorder and a fully integrated neural stimulator with charge balancing capability.

Clin Neurophysiol 2019 Jan 19. Epub 2019 Jan 19.

Department of Neurology, University of Leipzig, Liebigstr. 20, 04103 Leipzig, Germany.

Objective: Degeneration of nuclei of the brainstem, especially parts of the vagal nuclei complex and the reticular formation, in Parkinson's disease (PD) may in part be responsible for nonmotor signs like obstipation, cardiac dysfunction and rapid eye movement sleep behavior disorder (RBD). The aim of the study was to establish a new blink reflex (BR) variant involving the vagal nuclei complex and the reticular formation and to investigate BR comprehensively using 3 different afferent routes in PD.

Methods: In this cross-sectional observational study in 30 PD patients and 30 age and sex matched healthy controls, BR was elicited by stimulation of the auricular branch of the vagus nerve (ABVN) and compared to conventional BR variants evoked by the trigeminal and median nerve. Read More

Recording and Decoding of Vagal Neural Signals Related to Changes in Physiological Parameters and Biomarkers of Disease.

Cold Spring Harb Perspect Med 2019 Jan 22. Epub 2019 Jan 22.

Center for Bioelectronic Medicine, The Feinstein Institute for Medical Research, Donald & Barbara Zucker School of Medicine at Hofstra/Northwell, Manhasset, New York 11030.

Our bodies have built-in neural reflexes that continuously monitor organ function and maintain physiological homeostasis. Whereas the field of bioelectronic medicine has mainly focused on the stimulation of neural circuits to treat various conditions, recent studies have started to investigate the possibility of leveraging the sensory arm of these reflexes to diagnose disease states. To accomplish this, neural signals emanating from the body's built-in biosensors and propagating through peripheral nerves must be recorded and decoded to identify the presence or levels of relevant biomarkers of disease.

Precious cargo: Modulation of the mesenteric lymph exosome payload after hemorrhagic shock.

J Trauma Acute Care Surg 2019 Jan;86(1):52-61

From the Division of Trauma, Surgical Critical Care, Burns and Acute Care Surgery, Department of Surgery, University of California San Diego Health, San Diego, California (E.C.W., T.W.C., A.B., B.P.E., T.W.C.); and Riverside University Health System Medical Center, Loma Linda University School of Medicine, Moreno Valley, California (R.C.).

Background: Trauma/hemorrhagic shock (T/HS) causes a release of proinflammatory mediators into the mesenteric lymph (ML) that may trigger a systemic inflammatory response and subsequent organ failure. Recently, we showed that exosomes in postshock ML are biologically active mediators of this inflammation. Because the specific inflammatory mediators in postshock ML exosomes have yet to be characterized, we hypothesized that T/HS would lead to a distinct ML proinflammatory exosome phenotype that could be identified by proteomic analysis.

Gerald A Dienel

Physiol Rev 2019 01;99(1):949-1045

Department of Neurology, University of Arkansas for Medical Sciences , Little Rock, Arkansas ; and Department of Cell Biology and Physiology, University of New Mexico , Albuquerque, New Mexico.

Glucose is the long-established, obligatory fuel for brain that fulfills many critical functions, including ATP production, oxidative stress management, and synthesis of neurotransmitters, neuromodulators, and structural components. Neuronal glucose oxidation exceeds that in astrocytes, but both rates increase in direct proportion to excitatory neurotransmission; signaling and metabolism are closely coupled at the local level. Exact details of neuron-astrocyte glutamate-glutamine cycling remain to be established, and the specific roles of glucose and lactate in the cellular energetics of these processes are debated.

A challenge in treating epilepsy is the accurate documentation of seizure frequency, which is needed in order to assess the benefits of ongoing treatment. We present a 17-year-old girl who underwent video-based monitoring in order to establish an accurate seizure count before and after the implantation of a vagus nerve stimulator to treat refractory epilepsy. The results show a reduction in disabling seizure types after vagus nerve stimulator implantation and highlight the inconsistencies between the reported and actual seizure count in this patient.

Xinjiang Key Laboratory of Medical Animal Model Research, Clinical Medical Research Institute, First Affiliated Hospital of Xinjiang Medical University, Urumqi, China.

Background: Transcutaneous stimulation of the auricular branch of the vagus nerve (AB-VNS) is a potentially noninvasive, inexpensive, and safe approach for vagus nerve stimulation that suppresses the induction and duration of atrial fibrillation and reduces sympathetic nerve outflow in healthy humans. Researchers have not determined whether AB-VNS affects ventricular arrhythmias.

Objective: To evaluate the antiarrhythmic effects of noninvasive AB-VNS on ventricular arrhythmias induced by myocardial infarction (MI). Read More

Adenylyl Cyclase 6 Mediates Inhibition of TNF in the Inflammatory Reflex.

Front Immunol 2018 27;9:2648. Epub 2018 Nov 27.

Department of Medicine, Center for Bioelectronic Medicine, Center for Molecular Medicine, Solna, Karolinska Institutet, Karolinska University Hospital, Stockholm, Sweden.

Macrophage cytokine production is regulated by neural signals, for example in the inflammatory reflex. Signals in the vagus and splenic nerves are relayed by choline acetyltransferase T cells that release acetylcholine, the cognate ligand for alpha7 nicotinic acetylcholine subunit-containing receptors (α7nAChR), and suppress TNF release in macrophages. Here, we observed that electrical vagus nerve stimulation with a duration of 0. Read More
