  1. 1. Assessment of central auditory functions : methods and applications

    University dissertation from Linköping : Linköpings University Electronic Press

    Author : Mathias Hällgren; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : Central auditory processing is complex and can not be completely evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests, cognitive tests that tax functions important for speech processing and electrophysiological tests.

  2. 2. Influence of depth of anesthesia on postoperative cognitive dysfunction (POCD) and inflammatory markers

    University dissertation from Örebro : Örebro universitet

    Author : Pether Jildenstål; Narinder Rawal; Lars Berggren; Jan Jakobsson; Johan Reader; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postoperative cognitive dysfunction; minor and major surgery; anaesthesia; depth of anaesthesia monitoring; auditory evoked potential; AAI; inflammatory marker; Medicin; Medicine;

    Abstract : Patients may suffer from various forms of postoperative cognitive dysfunction (POCD). In most cases, the impact on cognitive function is relatively transient but POCD can sometimes be long-lasting (> 1 year). Studies showing that up to one in four patients with known risk factors are affected by some form of cognitive loss. READ MORE

  3. 3. Auditory and Olfactory Abilities in Blind and Sighted Individuals More Similarities than Differences

    University dissertation from Stockholm : Department of Psychology, Stockholm University

    Author : Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; [2018]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absolute threshold; audition; autobiographical memory; blindness; discrimination; episodic recognition; identification; imagery; judgments of learning; memory; metacognition; olfaction; onset age of blindness; reminiscence bump; sensory compensation; psykologi; Psychology;

    Abstract : Blind individuals face various challenges in everyday life because of the lack of visual input. However, since they need to rely on the non-visual senses for everyday tasks, for instance, when navigating the environment, the question has been raised as to whether perceptual and cognitive abilities in these senses may be enhanced.

  4. 4. Novel neurophysiological monitors of the transition from wakefulness to loss of consciousness during anaesthesia

    University dissertation from Stockholm : Karolinska Institutet, Department of Surgical Science

    Author : Gunilla Barr; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EEG; BI-spectral index; AEP; propofol; sevoflurane; awareness;

    Abstract : Background: The concept of adequate anaesthesia is not easily defined. One important component of anaesthesia is the suppression of wakefulness, that is, a patient who does not experience sensory input such as hearing, vision, and feeling of pain. 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.
