  1. 1. Dream Experience - Phenomenology meets Cognitive Neuroscience

    Författare :Lennart Karlsson; Filosofiska institutionen; []
    Nyckelord :HUMANIORA; HUMANITIES; Philosophical logic; dream symbolism; neuroscience; delusional states; visual awareness; lucid dreaming; Phenomenology; dreaming; Teoretisk filosofi; logik;

    Sammanfattning : This treatise examines what I call the ‘traditional view’ on the phenomenology of dreaming. According to this view, dreams are experienced in more or less the same way as waking reality – that is, our experience of “being-in-the-dream” is very much like our experience of “being-in-the-world”.

  3. 2. Contours of Cognition

    Författare :Trond A. Tjøstheim; Kognitiv modellering; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; computational; cognitive; neuroscience; perception; memory; spatial cognition; trust; pupil dynamics; reflection; thinking; intelligence; reinforcement learning; foraging; allostasis; decision making;

    Sammanfattning : This thesis concerns the nature of cognition. It posits that cognitive processes primarily are means to maintain allostasis in organisms whose ecological niches require movement to approach food-resources and avoid predation. LÄS MER

  4. 3. Functional Analysis of the Vesicular Glutamate Transporter 2 in Specific Neuronal Circuits of the Brain

    Författare :Karin Nordenankar; Åsa Wallén-Mackenzie; Rainer Spanagel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; amphetamine; affective behaviour; cocaine; cognitive behaviour; conditional knockout mouse; dopamine; operant self-administration; reward system; schizophrenia; Neuroscience; Neurovetenskap;

    Sammanfattning : A key issue in neuroscience is to determine the connection between neuronal circuits and behaviour. In the adult brain, all neuronal circuits include a glutamatergic component. LÄS MER

  5. 4. The reserve concept in patients with Mild Cognitive Impairment – new approaches

    Författare :Sindre Rolstad; Göteborgs universitet; []
    Nyckelord :neuroscience; cognition; neuropsychology;

    Sammanfattning : The concept of reserve stems from the observation that premorbid factors, e.g. education, result in variation in the response to any kind of brain pathology. As subjects with higher reserve tolerate more neuropathology, symptomatic expression of pathology is delayed. LÄS MER

  7. 5. The conscious brain : Empirical investigations of the neural correlates of perceptual awareness

    Författare :Johan Eriksson; Lars Nyberg; Geraint Rees; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; consciousness; visual perception; object identification; functional neuroimaging; top-down processing; prefrontal cortex; auditory perception; Neuroscience; Neurovetenskap;

    Sammanfattning : Although consciousness has been studied since ancient time, how the brain implements consciousness is still considered a great mystery by most. This thesis investigates the neural correlates of consciousness by measuring brain activity with functional magnetic resonance imaging (fMRI) while specific contents of consciousness are defined and maintained in various experimental settings.
