The effect of cardiac contraction on collateral resistance in the canine heart. (1/2742)

We determined whether the coronary collateral vessels develop an increased resistance to blood flow during systole as does the cognate vascular bed. Collateral resistance was estimated by measuring retrograde flow rate from a distal branch of the left anterior descending coronary artery while the main left coronary artery was perfused at a constant pressure. Retrograde flow rate was measured before and during vagal arrest. We found that in 10 dogs the prolonged diastole experienced when the heart was stopped caused no significant change in the retrograde flow rate, which indicated that systole has little effect on the collateral resistance. However, when left ventricular end-diastolic pressure was altered by changing afterload or contractility, a direct relationship between end-diastolic pressure and collateral resistance was noted.  (+info)

Observations on some additional abnormalities in situs inversus viscerum. (2/2742)

The abnormal findings in a case of Situs inversus totalis are described. The duodenum was placed abnormally and retained its primitive mesentery. The proximal 22 in of jejunum were retroperitoneal. The attachment of the root of the mesentery to the posterior abdominal wall had a 7-shaped appearance, and there was a partial failure of the primitive mesocolon to adhere to the posterior abdominal wall. The common hepatic artery arose from the superior meseneric artery, which also provided a branch to the proximal jejunal loop. The right vagus nerve was found anterior to the oesophagus at the oesophageal hiatus in the diaphragm, and the left vagus was posterior. A double ureter was present on the right side. The findings are discussed in relation to mid-gut development.  (+info)

Pharmacodynamic actions of (S)-2-[4,5-dihydro-5-propyl-2-(3H)-furylidene]-1,3-cyclopentanedione (oudenone). (3/2742)

The pharmacodynamic actions of (S)-2-[4,5-dihydro-5-propyl-2(3H)-furylidene]-1,3-cyclopentanedione (oudenone) were studied in both anesthetized animals and isolated organs. Oudenone (10--40 mg/kg i.v.) induced an initial rise in blood pressure followed by a prolonged hypotension in the anesthetized rats. In unanesthetized spontaneously hypertensive rats (SHR), oudenone (5--200 mg/kg p.o.) caused a dose-related decrease in the systolic blood pressure. The initial pressor effect was diminished by pretreatments with phentolamine, guanethidine, hexamethonium and was abolished in the pithed rats. In addition, intracisternal administrations of oudenone (100--600 mug/kg) showed a marked increase in blood pressure in the anesthetized rats, suggesting that the pressor effect may be due to centrally mediated actions. Oudenone, given intra-arterially into the femoral artery (400--800 mug/kg), caused a long-lasting vasodilation in anesthetized dogs. At a relatively high dose (40 mg/kg i.v.), oudenone antagonized all pressor responses to autonomic agents and central vagus nerve stimulation in anesthetized rats and dogs, however, oudenone showed no anti-cholinergic,-histaminergic, beta-adrenergic and adrenergic neuron blocking properties.  (+info)

Adventitial delivery minimizes the proinflammatory effects of adenoviral vectors. (4/2742)

PURPOSE: Adenovirus-mediated arterial gene transfer is a promising tool in the study of vascular biology and the development of vascular gene therapy. However, intraluminal delivery of adenoviral vectors causes vascular inflammation and neointimal formation. Whether these complications could be avoided and gene transfer efficiency maintained by means of delivering adenoviral vectors via the adventitia was studied. METHODS: Replication-defective adenoviral vectors encoding a beta-galactosidase (beta-gal) gene (AdRSVnLacZ) or without a recombinant gene (AdNull) were infused into the lumen or the adventitia of rabbit carotid arteries. Two days after infusion of either AdRSVnLacZ (n = 8 adventitial, n = 8 luminal) or AdNull (n = 4 luminal), recombinant gene expression was quantitated by histochemistry (performed on tissue sections) and with a beta-gal activity assay (performed on vessel extracts). Inflammation caused by adenovirus infusion was assessed 14 days after infusion of either AdNull (n = 6) or vehicle (n = 6) into the carotid adventitia. Inflammation was assessed by means of examination of histologic sections for the presence of neointimal formation and infiltrating T cells and for the expression of markers of vascular cell activation (ICAM-1 and VCAM-1). To measure the systemic immune response to adventitial infusion of adenovirus, plasma samples (n = 3) were drawn 14 days after infusion of AdNull and assayed for neutralizing antibodies. RESULTS: Two days after luminal infusion of AdRSVnLacZ, approximately 30% of luminal endothelial cells expressed beta-gal. Similarly, 2 days after infusion of AdRSVnLacZ to the adventitia, approximately 30% of adventitial cells expressed beta-gal. beta-gal expression was present in the carotid adventitia, the internal jugular vein adventitia, and the vagus nerve perineurium. Elevated beta-gal activity (50- to 80-fold more than background; P <.05) was detected in extracts made from all AdRSVnLacZ-transduced arteries. The amount of recombinant protein expression per vessel did not differ significantly between vessels transduced via the adventitia (17.1 mU/mg total protein [range, 8.1 to 71.5]) and those transduced via a luminal approach (10.0 mU/mg total protein [range, 3.9 to 42.6]). Notably, adventitial delivery of AdNull did not cause neointimal formation. In addition, vascular inflammation in arteries transduced via the adventitia (ie, T-cell infiltrates and ICAM-1 expression) was confined to the adventitia, sparing both the intima and media. Antiadenoviral neutralizing antibodies were present in all rabbits after adventitial delivery of AdNull. CONCLUSION: Infusion of adenoviral vectors into the carotid artery adventitia achieves recombinant gene expression at a level equivalent to that achieved by means of intraluminal vector infusion. Because adventitial gene transfer can be performed by means of direct application during open surgical procedures, this technically simple procedure may be more clinically applicable than intraluminal delivery. Moreover, despite the generation of a systemic immune response, adventitial infusion had no detectable pathologic effects on the vascular intima or media. For these reasons, adventitial gene delivery may be a particularly useful experimental and clinical tool.  (+info)

Simultaneous identification of static and dynamic vagosympathetic interactions in regulating heart rate. (5/2742)

We earlier reported that stimulation of either one of the sympathetic and vagal nerves augments the dynamic heart rate (HR) response to concurrent stimulation of its counterpart. We explained this phenomenon by assuming a sigmoidal static relationship between nerve activity and HR. To confirm this assumption, we stimulated the sympathetic and/or vagal nerve in anesthetized rabbits using large-amplitude Gaussian white noise and determined the static and dynamic characteristics of HR regulation by a neural network analysis. The static characteristics approximated a sigmoidal relationship between the linearly predicted and the measured HRs (response range: 212.4 +/- 46.3 beats/min, minimum HR: 96.0 +/- 28.4 beats/min, midpoint of operation: 196.7 +/- 31.3 beats/min, maximum slope: 1.65 +/- 0.51). The maximum step responses determined from the dynamic characteristics were 7.9 +/- 2.9 and -14.0 +/- 4.9 beats. min-1. Hz-1 for the sympathetic and the vagal system, respectively. Because of these characteristics, changes in sympathetic or vagal tone alone can alter the dynamic HR response to stimulation of the other nerve.  (+info)

Hypoxia inhibits baroreflex vagal bradycardia via a central action in anaesthetized rats. (6/2742)

It is known that arterial baroreflexes are suppressed in stressful conditions. The present study was designed to determine whether and how hypoxia affects arterial baroreflexes, especially the heart rate component, baroreflex vagal bradycardia. In chloralose-urethane-anaesthetized rats, baroreflex vagal bradycardia was evoked by electrical stimulation of the aortic depressor nerve, and the effect of 15 s inhalation of hypoxic gas (4% O2) was studied. Inhalation of hypoxic gas was found to inhibit baroreflex vagal bradycardia. The inhibition persisted after bilateral transection of the carotid sinus nerve. Cervical vagus nerves were cut bilaterally and their peripheral cut ends were stimulated to provoke vagal bradycardia of peripheral origin so as to determine whether hypoxia could inhibit vagal bradycardia by acting on a peripheral site. In contrast to baroreflex vagal bradycardia, the vagus-induced bradycardia was not affected by hypoxic gas inhalation. It is concluded that baroreflex vagal bradycardia is inhibited by hypoxia and the inhibition is largely mediated by its direct central action.  (+info)

Interleukin-1beta in immune cells of the abdominal vagus nerve: a link between the immune and nervous systems? (7/2742)

Intraperitoneal administration of the cytokine interleukin-1beta (IL-1beta) induces brain-mediated sickness symptoms that can be blocked by subdiaphragmatic vagotomy. Intraperitoneal IL-1beta also induces expression of the activation marker c-fos in vagal primary afferent neurons, suggesting that IL-1beta is a key component of vagally mediated immune-to-brain communication. The cellular sources of IL-1beta activating the vagus are unknown, but may reside in either blood or in the vagus nerve itself. We assayed IL-1beta protein after intraperitoneal endotoxin [lipopolysaccharide (LPS)] injection in abdominal vagus nerve, using both an ELISA and immunohistochemistry, and in blood plasma using ELISA. IL-1beta levels in abdominal vagus nerve increased by 45 min after LPS administration and were robust by 60 min. Plasma IL-1beta levels increased by 60 min, whereas little IL-1beta was detected in cervical vagus or sciatic nerve. IL-1beta-immunoreactivity (IR) was expressed in dendritic cells and macrophages within connective tissues associated with the abdominal vagus by 45 min after intraperitoneal LPS injection. By 60 min, some immune cells located within the nerve and vagal paraganglia also expressed IL-1beta-IR. Thus, intraperitoneal LPS induced IL-1beta protein within the vagus in a time-frame consistent with signaling of immune activation. These results suggest a novel mechanism by which IL-1beta may serve as a molecular link between the immune system and vagus nerve, and thus the CNS.  (+info)

Inspiration-promoting vagal reflex under NMDA receptor blockade in anaesthetized rabbits. (8/2742)

1. This study describes a novel vagal respiratory reflex in anaesthetized rabbits. In contrast to the well-known inspiratory (I) off-switching by vagal afferent excitation, this vagal reflex initiates and maintains the central I activity of phrenic nerve discharges in rabbits pre-treated with antagonists of N-methyl-D-aspartate-type excitatory amino acid receptors (NMDA-Rs). 2. Under NMDA-R blockade with either dizocilpine (0.025-0.3 mg kg-1), D-2-amino-5-phosphonopentanoic acid (AP5, 0.5-1 mg, i.c.v.) or ketamine (10 mg kg-1), vagal stimulation at low frequencies (5-40 Hz) during the I phase prevented or markedly delayed the spontaneous I termination. In contrast, stimulation of the same vagal afferent at the same intensity but at a higher frequency (100-160 Hz) during the I phase immediately terminated the I phase. 3. In non-vagotomized rabbits, maintaining the tidal volume at end-expiratory levels during the I phase prevented spontaneous I termination and maintained apneusis after NMDA-R blockade with dizocilpine. 4. Brief stimulation of vagal afferents at low frequency (5-40 Hz) during the expiratory (E) phase constantly initiated phrenic I discharge after NMDA-R block. 5. We conclude that low-frequency discharge of vagal pulmonary stretch receptor afferents, as when lung volume is near functional residual capacity, promotes central I activity under NMDA-R blockade.  (+info)

Peter, The vagus nerve sends projections to much of the body visceral organs. It originates in the brain stem and is very important in the control of heart rate, gastric motility, digestive, and metabolic activities. When the vagus sends messages to the heart, the heart rate slows. When the vagus sends messages to salivary glands, they secrete saliva. Vagal stimulation of the pupil causes the aperature to close (mydriasis.) One common term used in conjunction with vagal function is vagal tone. Increased vagal tone results in a slower heart rate, [INCREASED]salivary secretions, and pupillary constriction. Decreased vagal tone has the opposite effects. It is possible to inhibit the actions of the vagus which would decrease vagal tone, but that is probably not what is implied by vagal inhibition. You see vagal inhibition a potentially sloppy phrase. Vagal inhibition of the heart slows the heart rate. Inhibition of the vagus accelerates the heart rate. rlh At 7:47 PM +0100 4/11/99, Peter Moss wrote: ...

Vagus Nerve. Vagus nerve, also called X cranial nerve or 10th cranial nerve, longest and most complex of the cranial nerves. The vagus nerve runs from the brain through the face and thorax to the abdomen. It is a mixed nerve that contains parasympathetic fibres. The vagus nerve has two sensory ganglia (masses of nerve tissue that transmit sensory impulses): the superior and the inferior ganglia. The branches of the superior ganglion innervate the skin in the concha of the ear. The inferior ganglion gives off two branches: the pharyngeal nerve and the superior laryngeal nerve. The recurrent laryngeal nerve branches from the vagus in the lower neck and upper thorax to innervate the muscles of the larynx (voice box). The vagus also gives off cardiac, esophageal, and pulmonary branches. In the abdomen the vagus innervates the greater part of the digestive tract and other abdominal viscera.. The vagus nerve has the most extensive distribution of the cranial nerves. Its pharyngeal and laryngeal ...
We have conducted a registry study of almost 15,000 patients who have had the vagus nerve in their stomach severed. Between approximately 1970-1995 this procedure was a very common method of ulcer treatment. If it really is correct that Parkinsons starts in the gut and spreads through the vagus nerve, then these vagotomy patients should naturally be protected against developing Parkinsons disease, explains postdoc at Aarhus University Elisabeth Svensson on the hypothesis behind the study.. A hypothesis that turned out to be correct:. Our study shows that patients who have had the the entire vagus nerve severed were protected against Parkinsons disease. Their risk was halved after 20 years. However, patients who had only had a small part of the vagus nerve severed where not protected. This also fits the hypothesis that the disease process is strongly dependent on a fully or partially intact vagus nerve to be able to reach and affect the brain, she says.. The research project has just been ...
the vagus nerve is one of many cranial nerves. So we have 12 pairs of cranial nerves, or nerves that begin within the head cavity, and they exit to the brainstem at that point.. The vagus nerve is the 10th pair of cranial nerves. So its called the 10th cranial nerve, as well. And theres one on each side. Theres actually one on the left and one on the right. So it is a pair and is the vagus nerves in reality. But the vagus nerve is the only cranial nerve of those 12 pairs that will exit the cranium. Okay. So it does have some function in and around the face and the throat, but it does exit and go into other areas of the body.. And thats what makes the vagus nerve so important. It is the only one that does so. And it goes to innervate so many different organs inside our body. This includes the heart, the lungs, stomach, gallbladder, liver, kidneys, every single part of our digestive tract, as well as our spleen. So all of these organs need to have a certain level of information thats passed ...

the body. The Vagus Nerve is responsible for such varied tasks as heart rate, gastrointestinal peristalsis, sweating, and quite a few muscle movements in the mouth, including speech (via the recurrent laryngeal nerve) and keeping the larynx open for breathing. It also receives some sensation from the outer ear, via the Auricular branch (also known as Aldermans nerve) and part of the meninges.. The Vagus nerve is used to regulate the heartbeat and the muscle movement necessary to keep you breathing. It is the responsibility of the Vagus nerve to shift blood as needed. It maintains blood flow to the brain at all times to keep us from fainting. This nerve also regulates the chemical levels in the digestive system so that the intestines can process food and keep track of what types of nutrients are being gained from the food that is taken in.

The increased incidence of pain syndromes requires the investigation of pathophysiological coherences as well as searching for new therapies. In the recent years neurostimulating techniques have been a promising approach regarding their analgesic effect. Combined with therapeutic standard procedures they can increase these effects and can have a positive impact on co-morbid diseases. The stimulation of the vagus nerve was proved as an efficient analgesic method in animal experiments and open clinical pilot studies amongst humans. Despite the lack of controlled approaches applying the method against defined pain syndromes, the stimulation of the vagus nerve has shown up as an effective method treating other psychiatric diseases like depression. The processing of stress, which is involved directly and indirectly in the pathogenesis of pain, seems to be susceptible for vagal stimulation. Compared with invasive methods the transcutaneous stimulation offers obvious advantages concerning appliance and ...

Neuroinflammation in utero may contribute to brain injury resulting in life-long neurological disabilities. The pivotal role of the efferent cholinergic anti-inflammatory pathway (CAP) in controlling inflammation, e.g., by inhibiting the HMGB1 release, via the macrophages α7 nicotinic acetylcholine receptor (α7nAChR) has been described in adults, but its importance in the fetus is unknown. Moreover, it is unknown whether CAP may also exert anti-inflammatory effects on the brain via the anatomically predominant afferent component of the vagus nerve. We measured microglial activation in the ovine fetal brain near term 24 h after the umbilical cord occlusions mimicking human labor versus controls (no occlusions) by quantifying HMGB1 nucleus-to-cytosol translocation in the Iba1+ and α7nAChR+ microglia. Based on multiple clinical studies in adults and our own work in fetal autonomic nervous system, we gauged the degree of CAP activity in vivo using heart rate variability measure RMSSD that reflects

The purpose of this study was to compare the distribution of effects of right and left efferent vagal stimulation on ventricular recovery properties in the in situ heart. To measure these effects in many areas simultaneously, local repolarization changes (local QT intervals) were recorded with bipolar electrodes in nine ventricular sites from 38 anesthetized dogs. In initial experiments, this method was shown to correlate with effective refractory period changes measured in the same test site after QT recording; vagal nerve stimulation prolonged the local QT interval by 1 ms for each 0.82 ms prolongation in effective refractory period (r = 0.87).. Simultaneous local QT recordings during vagal nerve stimulation demonstrated uniform prolongation with two exceptions. First, left vagal efferent stimulation prolonged local QT interval in the posterior left ventricular base more than did right vagal stimulation (5.9 ± 1.0 mean ± standard error of the mean versus 3.7 ± 0.9%, p , 0.05). This probably ...
The foregut develops from a cranial region of endoderm created after the initial cephalocaudal folding of the embryo. Starting at the stomodeum, a rapid expansion of the primitive gut forms the esophagus, from which the respiratory bud branches off.[2] During early foregut development, the esophagus lengthens considerably, reaching its proportional postnatal size. Simultaneously, the stomach begins to expand in width dorsally and ventrally in an asymmetric manner. This asymmetric expansion creates two curvatures, with the ventral side creating the lesser curvature and the dorsal side creating the greater curvature.[2] The expanding dorsal stomach wall then rotates the on its transverse plane, pulling its caudal portion upward and forcing the upper duodenum into a C shape. This rotation positions the left vagus nerve anteriorly and right vagus nerve posteriorly.[2] While the hindgut and midgut are only attached dorsally to the body wall by a fold of peritoneum, the foregut also has a ventral ...

Vagal Nerve Stimulation. One of the most exciting developments in the field of epilepsy treatment is the Vagal Nerve Stimulator (VNS). About the size of a hockey puck, the device is placed in the chest, with its wires around the vagus nerve. Once implanted, the epileptologist will program the VNS to deliver a series of stimulations to the vagus nerve at various strengths and frequencies.. VNS works by repetitively stimulating the vagus nerve for a period of time and then by pausing for a period of time. How this achieves an anti-epileptic effect is unknown but one theory is that the device scrambles some of the synchronous discharges of the brain.. The procedure can be useful in aborting a seizure in patients who can sense one about to start. And it can be helpful for family and caretakers in shortening seizures and allowing for faster recovery for those patients who cannot sense a seizure starting.. Though no more effective a treatment than medication, its does lack the central nervous system ...

The Vagus Nerve and Stress Did you know that when you find yourself freaking out, that your vagus nerve can be your best friend? Its the major nerve that runs along our spine in our chest and abdomen and stimulating it can kickstart our parasympathetic nervous system and help us relax. When life stressors trigger … Continue reading →. ...
A 40-year-old man presented with an insidious slowly enlarging nontender, firm, and movable mass on the right side of the neck for 3 years (figure 1). He had a 2-month history of paroxysmal cough and the cough could be elicited when the mass was palpated (video). MRI (figure 2) demonstrated that the mass involved the vagus nerve and displaced sternocleidomastoid muscle and the internal jugular vein laterally. The cough reflex is caused by stimulation of vagal nerve afferents.1,2 Microscopic dissection showed the tumor was in the carotid sheath and arose from a single fascicle of the vagus nerve. The pathologic diagnosis was schwannoma. After the surgery, the patient had a normal voice, with no evidence of paroxysmal cough or recurrence. ...
It is has branches located on both the left and right side of the body, and each branch will initially travel down to produce the auricular nerve. This branch supplies the external acoustic meatus or the ear canal. The branches also supply innervation to the pharynx. From here the right and left branches of the vagus nerve will enter the thorax to supply the organs located within the thorax and eventually down to the abdomen. This nerve will therefore innervate all the critical organs within this area except the adrenal gland, descending colon, rectum, and anus. Based on this it is possible to see the importance of this nerve in controlling the heart rate, digesting food, and regulating breathing. Thus there are quite a number of presentations in the symptoms of vagus nerve damage ...
Conclusions: Intraoperative neurophysiologic testing seems to be a feasible methodology for monitoring the perigastric vagus nerves. Innervation of the duodenum via the celiac branch and postoperative preservation of the function of the vagus nerves were confirmed in most patients.

The tone of the vagus nerve is key to activating the parasympathetic nervous system. Vagal tone is measured by tracking your heart-rate alongside your breathing rate. Your heart-rate speeds up a little when you breathe in, and slows down a little when you breathe out. The bigger the difference between your inhalation heart-rate and your exhalation heart-rate, the higher your vagal tone. Higher vagal tone means that your body can relax faster after stress. ...

What is high vagal tone associated with?High vagal tone improves the function of many body systems, causing better blood sugar regulation, reduced risk of stroke and cardiovascular disease, lower blood pressure, improved digestion via better production of stomach basic and digestive enzymes, and reduced migraines. Higher vagal tone is also associated with better mood, less anxiety and more stress resilience. One of the most interesting roles of the vagus nerve is that it essentially reads the gut microbiome and initiates a response to modulate inflammation based on whether or not it detects pathogenic versus non-pathogenic organisms. In this way, the gut microbiome can have an affect on your mood, stress levels and overall inflammation ...
Before reading this article, close your eyes and take a few slow, deep breaths. Feel a little calmer? Youve just tapped into your Vagus nerve.

Avoidance of Trauma or Impact. As you can see running a sub three-hour marathon doesnt appear in this list.. The brain subconsciously uses a number of pathways including the sympathetic nervous system (the fight or flight system) to enforce these priorities. Two pathways that are of interest from an endurance and athletic performance perspective are the vagus and golgi nerve pathways.. The Vagus Nerve. The vagus nerve is actually part of our parasympathetic nervous system, which controls all organs except for the adrenal glands (part of the sympathetic nervous system). Specifically of interest for us athletes, the vagus nerve lowers cardiac output. Ever wondered what actually controls maximum heart rate? Thats the vagus nerve.. When the brain senses (or more importantly believes) it is at risk - through, for example, decreased oxygen in the blood - it will decrease cardiac rate, essentially slowing us down so that more oxygen and blood glucose is available to the brain rather than the ...

The electro-stimulation performed with stimuli of high frequency, low intensity and moderately long duration (rectangular waves of 1.5 V, 0.7 msec, 100 Hz) consistently elicited systemic hypertension and vasoconstriction. This response was completely abolished by pretreatment with guanethidine or hexamethonium. On the other hand, electrostimulation with stimuli of low frequency, high intensity and long duration (5 V, 1 msec, 10 Hz) produced systcmic hypotension and ...

The Vagus Nerve is our 10th Cranial Nerve, the longest nerve in the body, connects all of our organs and is the key to getting us into Parasympathetic Nervous System. If the Vagus Nerve is stimulated and healthy, we will go into PSNS easily. If its shut down, constricted or weak, we will tend to be in SNS/survival.. The Vagus Nerve travels all throught the horse, and there are a few key places we can easily stimulate it. Equine Tapping is used to stimulate the Vagus Nerve and trigger the PSNS/rest/digest/play/learn/heal. ...
Stimulating the vagus nerve supports that tempering effect, but it can also somewhat excite the part of the nervous system that stimulates the immune response, which is counterproductive if youre looking to calm it.. Every circuit has a path coming from the brain and one going to the brain, and when you stimulate electrically, you usually have no control over which one you get. You usually get both. Patel said. These paths are often in the same nerve being stimulated.. The path leaving the brain and going toward other organs, called the efferent pathway, is the one to stimulate to temper the immune system and help relieve chronic inflammatory conditions. The one going to the brain, called the afferent pathway, if stimulated, leads eventually to the hypothalamus, a pea-sized region in the center of the brain. That triggers a chain of hormonal responses, eventually releasing cytokines, messaging molecules that promote inflammation.. You get a heightened inflammatory response when you stimulate ...
When you visit my website, you will notice there is much emphasis on the vagus nerve and hypothalamus. http://www.healthycitizens.com/east_west.htm#ad20010314and http://www.healthycitizens.com/east_west.htm#a20021026. 2 As the Gulf War Veterans experiences demonstrates, illnesses to either one are extremely difficult if not impossible to diagnose. Diabetes, depression, obesity, impotence, abdominal distention, high blood pressure are some of the other conditions connected with a dysfunctional vagus nerve and hypothalamus. Hypothalamus and vagus nerve is what much of the past 35+ years of my life as a guinea pig have been about. In the nineteen seventies at least three of my physicians unbeknownst to me were involved in research involving hypothalamus vagus nerve research. In my East Meets West Hill advertisement, I argue these conditions are treatable and treatments have been known for decades.
