Orienting attention to sound object representations attenuates change deafness.
According to the object-based account of attention, multiple objects coexist in short-term memory (STM), and we can selectively attend to a particular object of interest. Although there is evidence that attention can be directed to visual object representations, the assumption that attention can be oriented to sound object representations has yet to be validated. Here, we used a delayed match-to-sample task to examine whether orienting attention to sound object representations influences change detection within auditory scenes consisting of 3 concurrent sounds, each occurring at a different location. On some trials, the 2 ...

Midbrain responses to micro-stimulation of the cochlea using high density thin-film arrays.
Abstract A broader activation of auditory nerve fibres than normal using a cochlear implant contributes to poor frequency discrimination. As cochlear implants also deliver a restricted dynamic range, this hinders the ability to segregate sound sources. Better frequency coding and control over amplitude may be achieved by limiting current spread during electrical stimulation of the cochlea and positioning electrodes closer to the modiolus. Thin-film high density microelectrode arrays and conventional platinum ring electrode arrays were used to stimulate the cochlea of urethane-anaesthetized rats and responses compar...

Modulation of somatosensory abilities and the feeling of ear fullness in patients with acute sensorineural hearing loss
Abstract: Objective: Patients with acute sensorineural hearing loss (ASNHL) often complain of a feeling of ear fullness (FEF) that is similar to the sensation experienced during barometric pressure changes. This suggests that modulation of somatosensory abilities may relate to the manifestation of FEF, whereas it cannot simply be assumed that somatosensory abilities would be directly affected by ASNHL. To examine this possible relationship, we estimated somatosensory abilities of the tympanic membrane, and investigated the relationship between them and the manifestation of FEF.Methods: To estimate somatosensory abilities o...

Comparison and contrast of noise-induced hyperactivity in the dorsal cochlear nucleus and inferior colliculus.
In this study we compared the time courses and tonotopic distribution patterns of hyperactivity in the dorsal cochlear nucleus (DCN) and inferior colliculus (IC). A model of acquisition of hyperactivity in the IC by passive relay from the DCN would predict that the two nuclei show similar time courses and tonotopic profiles of hyperactivity. A model of acquisition of hyperactivity in the IC by compensatory plasticity mechanisms would predict that the IC and DCN would show differences in these features, since each adjusts to changes of spontaneous activity of opposite polarity. To test the role of these two mechanisms, anim...

Jervell and Lange-Nielson Syndrome masquerading as intractable epilepsy
We report a case of JLNS in a child who presented to us with refractory epilepsy. The cardiac cause of seizures was suspected as the child was hypotensive and pulseless during the episode of seizures. The child was diagnosed as JLNS based on Schwartz diagnostic criteria for LQTS and congenital sensorineural deafness. The child responded well to β-blocker therapy. Antiepileptic drugs were stopped. The screening of family members with ECG revealed a QT interval more than required for diagnosis of LQTS but they were asymptomatic. All asymptomatic family members were also put on metoprolol. All of them showed great...

Lateralized petrous internal carotid artery: imaging features and distinction from the aberrant internal carotid artery
Conclusion Lateralized petrous ICA can be identified on CT by its more posterolateral entrance to the skull base and protrusion into the anterior mesotympanum. It can be distinguished from the aberrant ICA which enters the posterior hypotympanum through an enlarged inferior tympanic canaliculus, then courses across the inferior cochlear promontory to connect with the normal horizontal petrous ICA. Lateralized ICA is best considered an incidental petrous ICA variant. Awareness of this entity is important in the presurgical evaluation of the temporal bone to avoid vascular injury and confusion with the congeni...

Synaptic plasticity in the medial superior olive of hearing, deaf, and cochlear‐implanted cats
AbstractThe medial superior olive (MSO) is a key auditory brainstem structure that receives binaural inputs and is implicated in processing interaural time disparities used for sound localization. The deaf white cat, a proven model of congenital deafness, was used to examine how deafness and cochlear implantation affected the synaptic organization at this binaural center in the ascending auditory pathway. The patterns of axosomatic and axodendritic organization were determined for principal neurons from the MSO of hearing, deaf, and deaf cats with cochlear implants. The nature of the synapses was evaluated through electron...

An SNX10 mutation causes malignant osteopetrosis of infancy
Conclusions SNX10 was recently shown to interact with vacuolar type H+-ATPase (V-ATPase) which pumps protons at the osteoclast-bone interface. Mutations in TCIRG1, the gene encoding a subunit of the V-ATPase complex, account for the majority of cases of osteopetrosis. It is speculated that SNX10 is responsible for the vesicular sorting of V-ATPase from Golgi or for its targeting to the ruffled border. A mutation in SNX10 may therefore result in ‘secondary V-ATPase deficiency’ with a failure to acidify the resorption lacuna. Determination of the sequence of the SNX10 gene is warranted in molecularly undefined pa...

Somatic mosaicism and the phenotypic expression of COL2A1 mutations
AbstractMutations in COL2A1, the gene for type II‐collagen, can result in a wide variety of phenotypes depending upon the nature of the mutation. Dominant negative mutations tend to result in severe and often lethal skeletal dysplasias such as achondrogenesis type 2, Kniest dysplasia, and spondyloepiphyseal dysplasia congenita. Stickler syndrome, a condition characterized by ophthalmological and orofacial features, deafness and arthritis, usually, but not exclusively, results from haploinsufficiency. Overlapping features of all these disorders can also be seen in the same family. Rare reports have demonstrated that pheno...

Prevalence of mitochondrial diabetes in southwestern Finland: a molecular epidemiological study
Abstract Mitochondrial diabetes and deafness (MIDD) is a subtype of diabetes mellitus (DM) that most commonly results from the m.3243A > G mutation in mitochondrial DNA (mtDNA). Sensorineural hearing loss is a typical accompanying feature. Previous studies have suggested a prevalence of ~1–1.5 % for MIDD. We studied the molecular epidemiology of MIDD among young (aged 18–45 years) adults in a defined population in southwestern Finland. Of the identified cohort of 1,532 patients with DM, we received blood samples of 299 patients and analyzed them for the m.3243A > G mut...

Contractility in Type III Cochlear Fibrocytes Is Dependent on Non-muscle Myosin II and Intercellular Gap Junctional Coupling
Abstract The cochlear spiral ligament is a connective tissue that plays diverse roles in normal hearing. Spiral ligament fibrocytes are classified into functional sub-types that are proposed to carry out specialized roles in fluid homeostasis, the mediation of inflammatory responses to trauma, and the fine tuning of cochlear mechanics. We derived a secondary sub-culture from guinea pig spiral ligament, in which the cells expressed protein markers of type III or “tension” fibrocytes, including non-muscle myosin II (nmII), α-smooth muscle actin (αsma), vimentin, connexin43 (cx43), and aquaporin-1.
