Neuroimaging of human auditory cortex

Modern neuroimaging technologies provide us with non-invasive methods for study- ing structure and function, and plasticity of the human auditory cortex. Here we have acquired high spatial resolution functional magnetic resonance imaging (fMRI) data of the ...

High-Resolution fMRI of Auditory Cortical Map Changes in Unilateral Hearing Loss and Tinnitus

Dimitri Nestor Alice Van De Ville, Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh, Stephanie Clarke

Animal models of hearing loss and tinnitus observe pathological neural activity in the tonotopic frequency maps of the primary auditory cortex. Here, we applied ultra high-field fMRI at 7 T to test whether human patients with unilateral hearing loss and ti ...

Implant-based three-dimensional superimposition of the growing mandible in a rabbit model

The reliable assessment of craniofacial morphological changes during growth requires invariant regions for image registration. As these regions have not yet been identified in three dimensions, intra-osseous implants are required as fiducial markers for th ...

Characterization of pulse amplitude and pulse rate modulation for a human vestibular implant during acute electrical stimulation

Silvestro Micera, Thuy Anh Khoa Nguyen, Maurizio Ranieri

Objective. The vestibular system provides essential information about balance and spatial orientation via the brain to other sensory and motor systems. Bilateral vestibular loss significantly reduces quality of life, but vestibular implants (VIs) have demo ...

The vestibular implant: frequency-dependency of the electrically evoked vestibulo-ocular reflex in humans

Thuy Anh Khoa Nguyen, Maurizio Ranieri

The vestibulo-ocular reflex (VOR) shows frequency-dependent behavior. This study investigated whether the characteristics of the electrically evoked VOR (eVOR) elicited by a vestibular implant, showed the same frequency-dependency. Twelve vestibular electr ...

Conducting polymer electrodes for auditory brainstem implants

Stéphanie Lacour, Nicolas Vachicouras, Amélie Anne Guex

The auditory brainstem implant (ABI) restores hearing in patients with damaged auditory nerves. One of the main ideas to improve the efficacy of ABIs is to increase spatial specificity of stimulation, in order to minimize extra-auditory side-effects and to ...

Finite element modelling of the bone-implant interface and experimental validation

Céline Samira Wyss

Excessive interfacial micromotion endangers the implant primary stability by favoring the formation of a fibrous tissue layer at the bone-implant interface. It was recently proposed that implant micromotion induces fluid flow in the granulation tissue that ...

Novel micropatterns mechanically control fibrotic reactions at the surface of silicone implants

Dominique Pioletti, Hicham Majd, Michael Friedrich, Boris Hinz, Silvio Ramondetti, Giorgio Pietramaggiori

Over the past decade, various implantable devices have been developed to treat diseases that were previously difficult to manage such diabetes, chronic pain, and neurodegenerative disorders. However, translation of these novel technologies into clinical pr ...

Optogenetic stimulation of the cochlear nucleus using channelrhodopsin-2 evokes activity in the central auditory pathways

Stéphanie Lacour

Optogenetics has become an important research tool and is being considered as the basis for several neural prostheses. However, few studies have applied optogenetics to the auditory brainstem. This study explored whether optical activation of the cochlear ...

Finite element modelling of micromotion at the bone-implant interface

Madge Audrey Marie Martin

A good implant primary stability is closely associated with long-term success of total hip arthroplasty. Excessive interfacial micromotion around the femoral component after cementless hip replacement is related to aseptic loosening of the stem and affects ...
