  1. 1. The Human Spiral Ganglion

    University dissertation from Umeå : Umeå university

    Author : Sven Tylstedt; Umeå universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; MEDICINE Surgery Otorhinolaryngology; MEDICIN Kirurgi Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. READ MORE

  2. 2. Strategies in Cochlear Nerve Regeneration, Guidance and Protection Prospects for Future Cochlear Implants

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fredrik Edin; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human vestibular nerve; Scarpa s ganglion; Stem cells; Nanoparticles; Nanocrystalline diamond; Oto-Rhino-Laryngology; Oto-rhino-laryngologi; Medical Science; Medicinsk vetenskap;

    Abstract : Today, it is possible to restore hearing in congenitally deaf children and severely hearing-impaired adults through cochlear implants (CIs). A CI consists of an external sound processor that provides acoustically induced signals to an internal receiver. READ MORE

  3. 3. Stem cell in-vitro strategies for the induction of sensory neurons for inner ear cell therapy

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Rouknuddin Qasim Ali; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The cochlea, a part of the auditory system, is a complex structure consisting of several different types of cells including hair cells and spiral ganglion neurons. In mammals, the regenerative potential of hair cells and spiral ganglion neurons is lost soon after the birth and damage to any of these cells causes sensorineural hearing loss. READ MORE

  4. 4. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Yeasmin Tahera; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPA axis; corticosterone; glucocorticoid receptor; NFêB; spiral ganglion neurons; cochlea; acoustic trauma; paraventricular nucleus;

    Abstract : The hypothalamic pituitary adrenal axis (HPA axis) regulates nearly all neuroendocrine responses of the body. An active HPA axis is crucial to maintaining homeostasis. An altered reactivity of the HPA axis can affect several physiological systems including the auditory system. READ MORE

  5. 5. Investigating a cell replacement therapy in the inner ear

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Neuroscience

    Author : Zhengqing Hu; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult neural stem cell; Cell therapy; Differentiation; Dorsal root ganglion; Embryonic stem cell; Gene transfer; Hearing loss; Nerve growth factor; Neurogenin; Organ of Corti; Spiral ganglion; Transplantation;

    Abstract : The mammalian auditory system is sensitive to genetic disorders, aging and injuries caused by overstimulation, ototoxic drugs and viral infections. Since the sensory epithelium (the organ of Corti) and the spiral ganglion neurons (SGNs) in adult mammalian do not regenerate spontaneously when they are damaged, a cell substitution strategy was proposed to compensate the function of the degenerated SGNs.
