Influencing connectivity and cross-frequency coupling by real-time source localized neurofeedback of the posterior cingulate cortex reduces tinnitus related distress
Conclusion This suggests that neurofeedback could remove the information, processed in beta and gamma, from the carrier wave, alpha, which transports the high frequency information and influences the salience attributed to the tinnitus sound. Based on the observation that much pathology is the result of an abnormal functional connectivity within and between neural networks various pathologies should be considered eligible candidates for the application of source localized EEG based neurofeedback training.

[Idiopathic intracranial hypertension as a cause of headache].
Abstract Idiopathic intracranial hypertension (IIH) is characterised by increased intracranial pressure with normal cerebrospinal fluid, and no evidence of space occupying process, meningeal pathology or venous thrombosis. The condition is associated with obesity, especially in women of childbearing age. IIH is a rare but serious cause of headache, and constitutes a differential diagnosis for sudden-onset headache, particularly if the patient has visual disturbances not related to migraine and reports pulsatile tinnitus, cranial nerve palsy or radiculopathy.

Robustness and dynamicity of functional networks in phantom sound
Publication date: 1 February 2017 Source:NeuroImage, Volume 146 Author(s): Anusha Mohan, Dirk De Ridder, Sven Vanneste Phantom sound perception is the perception of a sound in the absence of a corresponding external sound source. It is a common symptom for which no treatment exists.

Blast-induced tinnitus and hyperactivity in the auditory cortex of rats
In this study, we induced tinnitus in rats using blast exposure and investigated changes in spontaneous firing and bursting activity in the auditory cortex (AC) at one day, one month, and three months after blast exposure. Our results showed that spontaneous activity in the tinnitus-positive group began changing at one month after blast exposure, and manifested as robust hyperactivity at all frequency regions at three months after exposure. We also observed an increased bursting rate in the low-frequency region at one month after blast exposure and in all frequency regions at three months after exposure. Taken together, sp...

Audiologic characteristics in a sample of recently-separated military Veterans: The Noise Outcomes in Servicemembers Epidemiology Study (NOISE Study).
Abstract Military Service Members are often exposed to high levels of occupational noise, solvents, and other exposures that can be damaging to the auditory system. Little is known about hearing loss and how it progresses in Veterans following military service. This epidemiology study is designed to evaluate and monitor a cohort of Veterans for 20 years or more to determine how hearing loss changes over time and how those changes are related to noise exposure and other ototoxic exposures encountered during military service. Data reported here are from baseline assessments of the first 100 study participants (84 ma...

Surgical outcomes of middle fossa approach in intracanalicular vestibular schwannoma.
CONCLUSION: Middle fossa approach (MFA) shows a hearing preservation rate of 86% and facial nerve function was preserved with HB grade I or II in 93%. MFA is a good treatment option for intra-canalicular vestibular schwannomas when surgical excision is needed. BACKGROUND: Surgical outcomes of vestibular schwannoma have progressively improved with the advancement of microsurgical instruments. MFA is known to have better chances to preserve hearing, while it has limited access to the posterior fossa, limitation of tumor size, and higher risk of post-operative facial nerve weakness. OBJECTIVES: To investigate surgic...

Update on Idiopathic Intracranial Hypertension
Idiopathic intracranial hypertension (IIH) is a disorder of elevated intracranial pressure of unknown cause occurring predominantly in young women of childbearing age. The typical patient symptom profile is the presence of daily headache, pulse synchronous tinnitus, transient visual obscurations, and papilledema with its associated visual loss. Although surgical procedures are performed for those who fail medical therapy, their relative efficacy remains unclear. The main morbidity of IIH is from visual loss. This visual loss is present in most patients and can usually be reversed if recognized early in the patients ’...

Evidence that hidden hearing loss underlies amplitude modulation encoding deficits in individuals with and without tinnitus.
Abstract Damage to auditory nerve fibers that expresses with suprathreshold sounds but is hidden from the audiogram has been proposed to underlie deficits in temporal coding ability observed among individuals with otherwise normal hearing, and to be present in individuals experiencing chronic tinnitus with clinically normal audiograms. We tested whether these individuals may have hidden synaptic losses on auditory nerve fibers with low spontaneous rates of firing (low-SR fibers) that are important for coding suprathreshold sounds in noise while high-SR fibers determining threshold responses in quiet remain relativ...

An Integrative Tinnitus Model Based on Sensory Precision.
Abstract Tinnitus is a common disorder that often complicates hearing loss. Its mechanisms are incompletely understood. Current theories proposing pathophysiology from the ear to the cortex cannot individually - or collectively - explain the range of experimental evidence available. We propose a new framework, based on predictive coding, in which spontaneous activity in the subcortical auditory pathway constitutes a 'tinnitus precursor' which is normally ignored as imprecise evidence against the prevailing percept of 'silence'. Extant models feature as contributory mechanisms acting to increase either the intensit...

The Manifestation of Vortical and Secondary Flow in the Cerebral Venous Outflow Tract: An In Vivo MR Velocimetry Study
Aberrations in flow in the cerebral venous outflow tract (CVOT) have been implicated as the cause of several pathologic conditions including idiopathic intracranial hypertension (IIH), multiple sclerosis (MS), and pulsatile tinnitus (PT). The advent of 4D Flow magnetic resonance imaging (4D-Flow MRI) has recently allowed researchers to evaluate blood flow patterns in the arterial structures with great success. We utilized similar imaging techniques and found several distinct flow characteristics in the CVOT of subjects with and without lumenal irregularities. (Source: Journal of Biomechanics)

Long-Lasting forward Suppression of Spontaneous Firing in Auditory Neurons: Implication to the Residual Inhibition of Tinnitus
AbstractTinnitus is the perception of a sound that has no external source. Sound stimuli can suppress spontaneous firing in auditory neurons long after stimulus offset. It is unknown how changes in sound stimulus parameters affect this forward suppression. Using in vivo extracellular recording in awake mice, we found that about 40 % of spontaneously active inferior colliculus (IC) neurons exhibited forward suppression of spontaneous activity after sound offset. The duration of this suppression increased with sound duration and lasted about 40 s following a 30-s stimulus offset. Pure tones presented at the neuron...

Cervical spine disorders and its association with tinnitus: The “TRIPLE” hypothesis
Subjective Tinnitus and cervical spine disorders (CSD) are among the most common complaints encountered by physicians. Although the relationship between tinnitus and CSD has attracted great interest during the past several years, the pathogenesis of tinnitus induced by CSD remains unclear. Conceivably, CSD could trigger a somatosensory pathway-induced disinhibition of dorsal cochlear nucleus (DCN) activity in the auditory pathway; furthermore, CSD can cause inner ear blood impairment induced by vertebral arteries hemodynamic alterations and trigeminal irritation.
