Epicrania fugax (EF) was recently classified as a primary headache in the Appendix of the International Classification of Headache Disorders, third edition (ICHD-III). It is characterized by a paroxysmal pain rapidly radiating forward or backward along a linear or zigzag trajectory on the surface of the head. This article reports a 76-year-old woman who newly developed a paroxysmal EF-type pain distributed not only in the territories of the trigeminal and occipital nerves, but also in the territories of the cervical and thoracic nerves...

Exposure-based therapies help patients with post-traumatic stress disorder (PTSD) to extinguish conditioned fear of trauma reminders. However, controlled laboratory studies indicate that PTSD patients do not extinguish conditioned fear as well as healthy controls, and exposure therapy has high failure and dropout rates. The present study examined whether vagus nerve stimulation (VNS) augments extinction of conditioned fear and attenuates PTSD-like symptoms in an animal model of PTSD. To model PTSD, rats were subjected to a single prolonged stress (SPS) protocol, which consisted of restraint, forced swim, loss of consciousness, and 1 week of social isolation...

OBJECTIVES: The primary objective of the present study was to examine the relationship between suprathreshold electrically evoked compound action potential (ECAP) measures and speech recognition abilities in bilateral cochlear implant listeners. We tested the hypothesis that the magnitude of ear differences in ECAP measures within a subject (right-left) could predict the difference in speech recognition performance abilities between that subject's ears (right-left). DESIGN: To better control for across-subject variables that contribute to speech understanding, the present study used a within-subject design...

Nitric oxide (NO) activates the NO-sensitive soluble guanylate cyclase (NO-GC, sGC) and triggers intracellular signaling pathways involving cGMP. For survival of cochlear hair cells and preservation of hearing, NO-mediated cascades have both protective and detrimental potential. Here we examine the cochlear function of mice lacking one of the two NO-sensitive guanylate cyclase isoforms [NO-GC1 knockout (KO) or NO-GC2 KO]. The deletion of NO-GC1 or NO-GC2 did not influence electromechanical outer hair cell (OHC) properties, as measured by distortion product otoacoustic emissions, neither before nor after noise exposure, nor were click- or noise-burst-evoked auditory brainstem response thresholds different from controls...

In mammals, acoustic information arises in the cochlea and is transmitted to the ventral cochlear nuclei (VCN). Three groups of VCN neurons extract different features from the firing of auditory nerve fibers and convey that information along separate pathways through the brainstem. Two of these pathways process temporal information: octopus cells detect coincident firing among auditory nerve fibers and transmit signals along monaural pathways, and bushy cells sharpen the encoding of fine structure and feed binaural pathways...

Hemifacial spasm is a hyperactive cranial nerve disease mainly characterized by unilateral facial muscles paroxysmal, involuntary, irregular and clonic convulsion. Standard microvascular decompression is currently the most effective solution. During operation, it is pivotal to conduct a sharp dissection of arachnoid membrane around the caudal cranial nerves and facial, auditory nerves for fully exposure of pontomedullary sulcus, and lateral pontine region. In this article, the authors demonstrate a hemifacial spasm patient who underwent microvascular decompression successfully in their department...

Facial neural edema is the pathophysiological base of Bell's palsy. The middle cranial fossa approach is used to relieve the oppression of facial nerve at its most narrow course in the facial canal. In this research, the authors mainly discussed the internal auditory canal segment of facial nerve, completely in the shadow of the bony structure, which is inconvenient for transmastoid decompression. Therefore, the objective was to explore the definite position of the fundus meatus acustici interni from internal acoustic pore...

Morphologically congenital sensorineural hearing loss can be investigated under two categories. Majority of the congenital hearing loss (80%) are membranous malformations. Here the pathology involves inner ear hair cells. There is no gross bony abnormality and therefore, in these cases, high resolution computerized tomography and MRI of the temporal bone reveal normal findings. Remaining 20% have various malformations involving the bony labyrinth and therefore, can be radiologically demonstrated by CT and MRI...

Cochlear implantation (CI) surgery is a very successful technique, performed on more than 300,000 people worldwide. However, since the challenge resides in obtaining an accurate surgical planning, computational models are considered to provide such accurate tools. They allow us to plan and simulate beforehand surgical procedures in order to maximally optimize surgery outcomes, and consequently provide valuable information to guide pre-operative decisions. The aim of this work is to develop and validate computational tools to completely assess the patient-specific functional outcome of the CI surgery...

Epilepsy is a chronic medical disease in one third of patients and is associated with comorbid adverse somatic conditions due to epilepsy itself or its long-term treatment with antiepileptic drugs (AEDs). Data from experimental, cross-sectional and prospective studies have evidence for the deleterious effect of some AEDs on the auditory and vestibular systems. These abnormalities may be reversible or irreversible. Areas covered: This article review the evidence that long-term treatment with some antiepileptic drugs (AEDs) [e...

Many studies have explored how neuromodulators affect synaptic function, yet little is known about how they modify computations at the microcircuit level. In the dorsal cochlear nucleus (DCN), a region that integrates auditory and multisensory inputs from two distinct pathways, serotonin (5-HT) enhances excitability of principal cells, predicting a generalized reduction in sensory thresholds. Surprisingly, we found that when looked at from the circuit level, 5-HT enhances signaling only from the multisensory input, while decreasing input from auditory fibers...

Inner hair cells (IHCs) in the cochlea are the mammalian phono-receptors, transducing sound energy into graded changes in membrane potentials, the so called "receptor potentials." Ribbon synapses between IHCs and auditory nerve neurons are responsible for converting receptor potentials into spike rates. The characteristics of auditory nerve responses to sound have been described extensively. For instance, persistent acoustic stimulation produces sensory adaptation, which is revealed as a reduction in neuronal spike rate with time constants in the range of milliseconds to seconds...
