  1. 1. Cognitive function studied in animal models of schizophrenia

    Författare :Erik Pålsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phencyclidine; nitric oxide; prepulse inhibition; latent; nitric oxide; prepulse inhibition; latent inhibition; habituation; NMDA receptor; rat; mouse; cognition; schizophrenia;

    Sammanfattning : Cognitive dysfunction is considered a core deficit of schizophrenia, which currently lacks effective pharmacological treatment. In order to identify novel and more effective drug treatments, translational experimental animal models of cognitive dysfunction are required. Schizophrenia-like symptoms can be induced in humans by phencyclidine (PCP). LÄS MER

  3. 2. Hearing and cognition in speech comprehension. Methods and applications

    Författare :Mathias Hällgren; Stig Arlinger; Birgitta Larsby; Arne Leijon; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; physiology; cognition; cognition disorders; dichotic listening tests; hearing loss; sensorineural; neuropsychological tests; speech perception; Audiology; Audiologi;

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

  4. 3. Longitudinal cognitive changes in medically and surgically treated patients with drug resistant partial epilepsy

    Författare :Lena Andersson-Roswall; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug resistant partial epilepsy; epilepsy surgery; longitudinal cognitive changes;

    Sammanfattning : When this study was initiated, there were few published longitudinal studies on cognition in medically treated patients with refractory epilepsy, and none included reassessment data from healthy controls. At the time there were no long-term reports on surgically treated epilepsy patients. LÄS MER

  5. 4. Brain Networks and Dynamics in Narcolepsy

    Författare :Natasha Morales Drissi; Maria Engström; Gunnar Cedersund; Fredrik Elinder; Birgitte Kornum; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Narcolepsy is a chronic sleep disorder, characterised by excessive daytime sleepiness with frequent uncontrollable sleep attacks. In addition to sleeprelated problems, changes in cognition have also been observed in patients with narcolepsy and has been linked to the loss of Orexin-A in a number of studies. LÄS MER

  7. 5. Pilots’ decision-making, emotions and cognitive performance in simulated environments

    Författare :Eduardo Rosa; Johan Willander; Igor Knez; Robert Ljung; Nicklas Dahlström; Eric Groen; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aviation; pilot; simulation; environment; decision-making; fatigue; cognition; emotion; physiology; flyg; pilot; simulering; miljö; beslutsfattande; trötthet; kognition; känslor; fysiologi;

    Sammanfattning : The aim of this thesis is to investigate pilots’ performances in distinct simulation environments as related to the phenomena of cognition, emotion and fatigue. By doing so, it provides psychological material to broaden the understanding and possibility to development of pilots’ non-technical skills category related to the operational context. LÄS MER
