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

    Författare :Mathias Hällgren; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : 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.

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

    Författare :Pether Jildenstål; Narinder Rawal; Lars Berggren; Jan Jakobsson; Johan Reader; Örebro universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; Stockholms universitet; []
    Nyckelord :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; Psychology; psykologi;

    Sammanfattning : 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.

  5. 4. Electrically evoked compound action potentials as a tool for programming cochlear implants in children

    Författare :Andreas Björsne; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cochlear implants; ECAP; Impedance; T-levels; C-levels;

    Sammanfattning : Cochlear implants are generally the best treatment for young children with a profound hearing loss (or worse) when ordinary hearing aids cannot provide enough auditory stimulation. For these youngest recipients, there must be a valid rationale for deciding the level of stimulation. LÄS MER

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

    Författare :Gunilla Barr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :EEG; BI-spectral index; AEP; propofol; sevoflurane; awareness;

    Sammanfattning : 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. LÄS MER
