  1. 1. Keeping Eye and Mind on the Road

    Författare :Trent Victor; Claes von Hofsten; John Wann; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Vision; Eye-movements; Driving; Attention; Distraction; Ventral stream; Dorsal stream; Road safety; Traffic crashes; Evaluation methodology; Psykologi; Psychology; Psykologi;

    Sammanfattning : This thesis is devoted to understanding and counteracting the primary contributing factor in traffic crashes: inattention. Foremost, it demonstrates the fundamental importance of proactive gaze in the road centre area for action guidance in driving. LÄS MER

  3. 2. Leptin targets in the brain regulating body weight : receptors and down-stream mediators of leptin in neurons of the hypothalamus and brainstem

    Sammanfattning : Obesity is a disease which has become a global epidemic that is beginning to replace undernutrition and infectious diseases as the most significant contributor to ill health in the world. In particular, obesity is associated with diabetes mellitus, hypertension and coronary heart disease. LÄS MER

  4. 3. Neuropeptide circuitries regulating food and water intake

    Författare :Christian Broberger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :agouti gene-related protein; anorexia mutation; arcuate nucleus; cholecystokinin; cocaine- and amphetamine-regulated transcript; coexistence; confocal microscopy; dorsal root ganglion; feeding; hypocretin; immunohistochemistry; in situ hybridization; melanin-concentrating hormone; nodose ganglion; nucleus tractus solitaxii; orexin; paraventricular nucleus; satiety; sensory neurones; pro-opiomelanocortin; vagus nerve;

    Sammanfattning : An adequate supply of nutrients through food intake is critical for survival, as evidenced by disorders such as obesity and anorexia, which in the long run may be life-threatening. Feeding behaviour is ultimately controlled by interacting neuronal populations in the brain. LÄS MER

  5. 4. On the mind's time : production, perception, and pianists performance of rhythms : neural correlates and neuroanatomical changes

    Författare :Sara L Bengtsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human movements are impressively flexible and precise. They are also coloured by the characteristics with which each person performs an act. This is evident in everyday activities, in sports, in art, and in music performance. LÄS MER

  7. 5. The role of transcriptional repression in Shh signalling and patterning of the ventral neural tube

    Författare :Madelen Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : From flies to humans, members of the Hedgehog (Hh) family of secreted signalling molecules play a vital role in determining cell fate and patterning during embryonic development. In vertebrates, Sonic Hedgehog (Shh) act in a graded manner to establish distinct neural progenitor populations at different concentration thresholds in the ventral neural tube. LÄS MER
