Abstract:

To further elucidate the functional anatomy of canine cardiac innervation as well as to assess the feasibility of producing regional left ventricular sympathetic denervation, the chronotropic and (or) regional left ventricular inotropic responses produced by stellate or middle cervical ganglion stimulation were investigated in 22 dogs before and after sectioning of individual major cardiopulmonary or cardiac nerves. Sectioning the right or left subclavian ansae abolished all cardiac responses produced by ipsilateral stellate ganglion stimulation. Sectioning a major sympathetic cardiopulmonary

Abstract:

The intracardiac parasympathetic neural elements that control sinus rate are found in the fatty tissue overlying the atrial junctions of the right pulmonary veins of mammalian hearts. We refer to these nerves as the sinus rate-related parasympathetic nerves (SRRPN). Thus, to elucidate the role of SRRPN, we studied the effects of cervical vagus stimulation on the positive chronotropic responses to cardiac sympathetic nerve stimulation and isoproterenol infusion before and after the SRRPN were removed in the open-chest anesthetized dog heart. Before SRRPN denervation, cervical vagus stimulation

Stimulation of a glossopharyngeal nerve caused vasodilation on both sides, the ipsilateral (-17.52%) being greater than the contralateral (-6.33%) response (P < 0.05).

Transcutaneous bilateral phrenic nerve stimulation (tPNS) is frequently used to assess diaphragmatic function in humans.

Abstract:

Background. Spinal cord injury (SCI) is a common severe trauma in clinic, hundreds of thousands of people suffer from which every year in the world. In terms of injury location, cervical spinal cord injury (CSCI) has the greatest impact. After cervical spinal cord injury, the lack of innervated muscles is not enough to provide ventilation and other activities to complete the respiratory function. In addition to the decline of respiratory capacity, respiratory complications also have a serious impact on the life of patients. The most commonly used assisted breathing and cough equipment is the v

Abstract:

Here we report a unique case of chronic occipital neuralgia caused by pathological vascular contact of the left greater occipital nerve. After 12 months of left-sided, unremitting occipital neuralgia, a hypesthesia and facial pain developed in the left hemiface. The decompression of the left greater occipital nerve from pathological contacts with the occipital artery resulted in immediate relief for hemifacial sensory change and facial pain, as well as chronic occipital neuralgia.

Electrical stimulation (50-150 microA, 0.5-ms duration, 3-300 Hz) was performed within three different regions (lateral, ventrolateral, and ventral) of the C2-C3 spinal cord of decerebrate, vagotomized, paralyzed, and artificially ventilated cats. Spinal cord stimulation sites were located by inserting monopolar or bipolar stimulating electrodes either at the dorsolateral sulcus or at least 1 mm medial or lateral to the sulcus. With stimulation at each site, alterations in respiratory rhythm, orthodromic phrenic nerve responses, and antidromic activation of medullary respiratory-modulated neur

Abstract Introduction Hypoglossal Nerve Stimulation (HGNS) has become an alternative therapy for moderate to severe obstructive sleep apnea (OSA) patients intolerant to PAP therapy. HGNS devices typically comprise of implantable pulse generator (IPG) placed surgically in an infraclavicular subcutaneous pocket. An electrode cuff attached to the IPG wraps around the distal portion of the of the hypoglossal nerve. This device has an implantable chest sensor that monitors the respiratory efforts.

Abstract:

Background: Cluster headache (CH) is the most painful and debilitating primary headache syndrome. Conventional treatment combines acute and prophylactic drugs. Also with maximal therapy a substantial proportion of patients do not experience a meaningful prevention or pain relief. Recent case series and early trials have suggested that occipital nerve stimulation can be very effective in the management of intractable CH. Methods: Seven patients with medically intractable chronic cluster headache were implanted with high cervical epidural electrodes. After a median test phase of 10 days (range 4

Abstract:

Headache following head injuries has been reported for centuries. The majority of post-traumatic headache (PTH) patients will report resolution of their complaints within a few months from the time of the initial injury. PTHs can contribute to disability, lost productivity, and health care costs. In this article we discuss a 40-year-old male with a history of motor vehicle accident and basal skull fracture. The patient had no headache history prior to the accident. He presented with more than 3 years persistent daily headache. The patient described constant throbbing and stabbing quality heada

1. The uterus, cervix, and vaginal canal are innervated by afferent fibers in the hypogastric and pelvic nerves. Four studies compared the innervation territory and sensitivity to peripheral stimuli of the two sets of fibers in adult virgin rats. 2. Innervation territory was studied anatomically by injecting different fluorescent dyes into different parts of the reproductive, lower urinary, and lower digestive tracts and examining retrogradely labeled neurons in dorsal root ganglia. It was also studied electrophysiologically in anesthetized rats by summing potentials evoked in branches of the

Abstract:

Object Spinal cord stimulation (SCS) is being currently used to treat medically refractory pain syndromes involving the face, trunk, and extremities. Unlike thoracic SCS surgery, during which patients can be awakened from conscious sedation to confirm good lead placement, safe placement of paddle leads in the cervical spine has required general anesthesia. Using intraoperative neurophysiological monitoring, which is routinely performed during these cases at the authors' institution, the authors developed an electrophysiological technique to intraoperatively lateralize lead placement in the cer

In addition, the left caudal pole and interganglionic nerves project onto the left lateral side of the heart as the left lateral cardiac nerve. These nerves contain afferent and (or) efferent axons which, upon stimulation, modify specific cardiac regions and (or) systemic pressure. In addition, with the exception o

Ventricular tachycardia with uniform beat-to-beat morphology was induced in 13 or 22 dogs by electrical stimulation of the left stellate ganglion (five experiments), the left middle cervical ganglion (four experiments), the left caudal pole cardiopulmonary nerve (two experiments), or the

Neuronal activity in the in situ middle cervical ganglion of dogs was investigated using extracellular recording techniques. The recorded action potentials were frequently active during specific phases of the cardiac cycle, particularly during systole, and this activity persisted following acute decentralization of the ganglion. The activity of these action potentials was modified when systemic arterial pressure was altered by isoproterenol, noradrenaline, adrenaline, or partial occlusion of the aorta, whether in the intact or acutely decentralized preparation.

Abstract:

OBJECTIVE Classically the 11th cranial nerve (CN XI, or accessory nerve) is described as having a cranial and a spinal root, the latter arising from the upper segments of the spinal cord through a number of very fine rootlets. According to classical knowledge, the cranial root gives motor innervation to the vocal cords, whereas the spinal root provides the motor innervation of the sternocleidomastoid muscle (SCM) and of the upper portions of the trapezius muscle (TZ). The specific function of each of the rootlets of the spinal component is not well known. Therefore the authors aimed to map, us
