Fig 1. The inflammatory reflex and how transcutaneous auricular vagus nerve stimulation may activate the pathway. Afferent vagus nerve fibers residing in the nodose ganglion are stimulated in the periphery by damageassociated molecular pattern molecules (DAMPs), including cytokines, and pathogen-associated molecular pattern molecules (PAMPs). The signals are transmitted to the nucleus of tractus solitarius (NTS). Reciprocal connections between the NTS and the dorsal motor nucleus (DMN) of the vagus mediate communication with and activation of efferent vagus fibers (motor vagus) from the DMN. The signal is propagated to the celiac ganglia, where the splenic nerve originates. Norepinephrine (NE) released from the splenic nerve interacts with beta2-adrenergic receptors (beta2-AR) on certain splenic T lymphocytes and causes the release of acetylcholine (ACh) from T cells containing choline acetyltransferase (TChAT cells). ACh interacts with a7-subunit-nicotinic acetylcholine receptors (a7nAChR) on macrophages and inhibits proinflammatory cytokine production and inflammation. Transcutaneous electrical stimulation of the auricular branch of the vagus nerve (ABVN) in the left ear also signals to the NTS and thus activates efferent vagus signals to the splenic TChAT cells. Abbreviations not explained in the text: ACTH= adrenocorticotropic hormone; VNS=vagus nerve stimulation.
Swedish Fig 1. Den inflammatoriska reflexen och hur transkutan aurikulär vagusnervstimulering kan aktivera vägen. Afferenta vagusnervfibrer som finns i nodosgangliet stimuleras i periferin av skadeassocierade molekylära mönstermolekyler (DAMPs), inklusive cytokiner, och patogenassocierade molekylära mönstermolekyler (PAMPs). Signalerna överförs till kärnan i tractus solitarius (NTS). Ömsesidiga kopplingar mellan NTS och den dorsalmotoriska kärnan (DMN) i vagus förmedlar kommunikation med och aktivering av efferenta vagusfibrer (motorvagus) från DMN. Signalen sprids till celiaki ganglierna, där mjältnerven har sitt ursprung. Noradrenalin (NE) frisatt från mjältnerven interagerar med beta2-adrenerga receptorer (beta2-AR) på vissa T-lymfocyter i mjälten och orsakar frisättning av acetylkolin (ACh) från T-celler som innehåller kolinacetyltransferas (TChAT-celler). ACh interagerar med a7-subunit-nikotinacetylkolinreceptorer (a7nAChR) på makrofager och hämmar proinflammatorisk cytokinproduktion och inflammation. Transkutan elektrisk stimulering av den aurikulära grenen av vagusnerven (ABVN) i vänster öra signalerar också till NTS och aktiverar därmed efferenta vagussignaler till mjältens TChAT-celler. Förkortningar som inte förklaras i texten: ACTH= adrenokortikotropt hormon; VNS=vagusnervstimulering.

BvS-> BUT – NB massage at the two red Points at the picture might be as effective, given you find out how to massage them – a kind of acupressure.
Vagus is our ”wandering nerv”, which together with GABA is our most important inhibitory functions. Pattern of Parasympathetic and Sympathetic oscillation can we measure and see in Respiratory Sinus (Arrhythmia, RSA) Rhythm (more correct while this is not actually an arrhythmia, but still called RSA.
