Purpose: Electrical neurostimulation enhances tear secretion, and can be applied to treatment of dry eye disease. Using a chronic implant, we evaluate the effects of stimulating the anterior ethmoid nerve on the aqueous, lipid, and protein content of secreted tears. Methods: Neurostimulators were implanted beneath the nasal mucosa in 13 New Zealand white rabbits. Stimulations (2.3-2.8 mA pulses of 75-875 μs in duration repeated at 30-100 Hz for 3 minutes) were performed daily, for 3 weeks to measure changes in tear volume (Schirmer test), osmolarity (TearLab osmometer), lipid (Oil-Red-O staining), and protein (BCA assay, mass spectrometry)...

PURPOSE OF REVIEW: Although chronic migraine (CM) is a common disorder that severely impacts patient functioning and quality of life, it is usually underdiagnosed, and treatment responses often remain poor even after diagnosis. In addition, effective treatment options are limited due to the rarity of randomized controlled trials (RCTs) involving patients with CM. In the present review, we discuss updated pharmacological, non-pharmacological, and neurostimulation treatment options for CM...

OBJECTIVES AND METHODS: A few published reports describe successful clinical use of low-frequency spinal cord stimulation (SCS) in the cervical spine resulting in bilateral upper and lower extremity pain relief. Major side-effect when using this modality of SCS is the uneven intensity of paresthesias which are frequently excessive in upper extremities while attempting to achieve optimal paresthesia coverage in all four extremities. RESULTS AND CONCLUSIONS: Here we describe a successful case of high frequency SCS at 10 kHz where profound control of neuropathic pain of all four extremities was achieved without the complication of paresthesias...

The human nervous system is a vast network carrying not only sensory and movement information, but also information to and from our organs, intimately linking it to our overall health. Scientists and engineers have been working for decades to tap into this network and 'crack the neural code' by decoding neural signals and learning how to 'speak' the language of the nervous system. Progress has been made in developing neural decoding methods to decipher brain activity and bioelectronic technologies to treat rheumatoid arthritis, paralysis, epilepsy and for diagnosing brain-related diseases such as Parkinson's and Alzheimer's disease...

The use of non-invasive brain neurostimulation (NIBS) techniques to treat neurological or psychiatric diseases is currently under development. Fatigue is a commonly observed symptom in the field of potentially treatable pathologies by NIBS, yet very little data has been published regarding its treatment. We conducted a review of the literature until the end of February 2017 to analyze all the studies that reported a clinical assessment of the effects of NIBS techniques on fatigue. We have limited our analysis to repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS)...

OBJECTIVE Dysfunction of distributed neural networks underlies many brain disorders. The development of neuromodulation therapies depends on a better understanding of these networks. Invasive human brain recordings have a favorable temporal and spatial resolution for the analysis of network phenomena but have generally been limited to acute intraoperative recording or short-term recording through temporarily externalized leads. Here, the authors describe their initial experience with an investigational, first-generation, totally implantable, bidirectional neural interface that allows both continuous therapeutic stimulation and recording of field potentials at multiple sites in a neural network...

Direct intracranial recording of human brain activity is an important approach for deciphering neural mechanisms of cognition. Such recordings, usually made in patients with epilepsy undergoing inpatient monitoring for seizure localization, are limited in duration and depend on patients' tolerance for the challenges associated with recovering from brain surgery. Thus, typical intracranial recordings, similar to most non-invasive approaches in humans, provide snapshots of brain activity in acute, highly constrained settings, limiting opportunities to understand long timescale and natural, real-world phenomena...

INTRODUCTION: Implantation of responsive neurostimulation (RNS) system has been previously discussed in the literature but there is a paucity of data on target accuracy and the use of intraoperative imaging. We describe our experience with eight patients using intraoperative computed tomography (iCT) during implantation of the NeuroPace(®) RNS system. METHODS: A frame based system was used. CT images were obtained and merged with preoperative MRI and metabolic imaging studies to calculate target coordinates...

Non-invasive, focal neurostimulation with ultrasound is a potentially powerful neuroscientific tool that requires effective transcranial focusing of ultrasound to develop. Time-reversal (TR) focusing using numerical simulations of transcranial ultrasound propagation can correct for the effect of the skull, but relies on accurate simulations. Here, focusing requirements for ultrasonic neurostimulation are established through a review of previously employed ultrasonic parameters, and consideration of deep brain targets...

Epilepsy is a highly prevalent chronic neurologic disorder and leads to social, behavioural, health and economic consequences. 'Treatment gap' varies from 10 per cent in developed countries to 75 per cent in low-income countries. Stigma and discrimination related to epilepsy are prevalent worldwide. Electroencephalography (EEG) is considered the most important tool for evaluating the patient with epilepsy. Video-EEG monitoring is an important tool for confirming the seizure type and estimating the epileptogenic zone in the brain...

We are reporting the case of a 32-year-old female who had suffered from fecal incontinence (FI). She was born with an imperforate anus and a recto-vaginal fistula; she underwent repair at 6 mo of age. At 29 years of age, she was still fecally incontinent despite extensive pelvic floor reeducation. A magnetic resonance imaging and an anal electromyography were performed. Because her symptoms were considered to be probably due to extra-sphincteric implantation of the neo-anus, a redo was performed of the recto-neo-anal intra-sphincteric anastomosis...

Multimodal analgesia provides quality analgesia, with fewer side effects due to the use of combined analgesics or analgesic techniques. Regional anaesthesia plays a fundamental role in achieving this goal. The different techniques of regional anaesthesia that include both peripheral and central blocks in either a single dose or in continuous infusion help to modulate the nociceptive stimuli that access the central level. The emergence of the ultrasound as an effective system to perform regional anaesthesia techniques has allowed the development of new regional anaesthesia techniques that formerly could not be carried out since only neurostimulation or skin references were used...

Small fiber neuropathy is a disorder of the peripheral nerves with typical symptoms of burning, sharp, and shooting pain and sensory disturbances in the feet. Pain treatment depends principally on the underlying etiology with concurrent administration of antidepressants, anticonvulsants, opioids, and topical treatments like capsaicin and local anesthetics. However, treatments for pain relief in these patients frequently fail. We describe the first case of intractable painful small fiber neuropathy of the foot successfully treated with spinal cord stimulation of the left L5 dorsal root ganglion...

BACKGROUND AND OBJECTIVES: Patients with complex regional pain syndrome (CRPS) confined to the knee are often therapy resistant. Neurostimulation is an accepted treatment for CRPS. Although results with dorsal column (DC) stimulation in patients with CRPS confined to the knee are often disappointing, the availability of dorsal root ganglion (DRG) stimulation may provide new opportunities for this complaint. Therefore, this study explores patients' preference for DC stimulation vs. DRG stimulation in treating chronic pain due to CRPS confined to the knee...

Millions of people around the world suffer from varying degrees of vision loss (including complete blindness) because of retinal degenerative diseases. Artificial retinal prosthesis, which is usually based on electrical neurostimulation, are the most advanced technology for different types of retinal degeneration. However, this technology involves placing a device into the eyeball, and such a highly invasive procedure is inevitably highly risk and expensive. Ultrasound has been demonstrated to be a promising technology for noninvasive neurostimulation, making it possible to stimulate the retina and induce action potentials similar to those elicited by light stimulation...
