  1. 21. Bully or Bullied? : The Zebrafish as a Model for Social Stress and Depression

    Författare :S Josefin Dahlbom; Svante Winberg; Jaap Koolhaas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroscience; Neurovetenskap;

    Sammanfattning : The zebrafish is evaluated as a model for social stress, depression and anxiety. I conclude that it is suitable, especially for studies of sex differences. In humans, women are more prone to depression but most animal studies are performed in males. LÄS MER

  3. 22. Discharges in human muscle afferents during manual tasks

    Författare :Michael Dimitriou; Benoni Edin; Roger Lemon; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor control; muscle spindle; Golgi tendon organ; muscle afferent; microneurography; proprioception; sensorimotor; fusimotor; hand; forward model; ; Neuroscience; Neurovetenskap;

    Sammanfattning : Muscle spindles are complex sensory organs that have been strongly implicated in the control and perception of movements. Human muscle spindles in relaxed muscles behave as stretch receptors, responding to the length and velocity of their parent muscles. LÄS MER

  4. 23. Neural Control of Movement : Motor Neuron Subtypes, Proprioception and Recurrent Inhibition

    Författare :Anders Enjin; Klas Kullander; Samuel L. Pfaff; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor neuron; proprioception; recurrent inhibition; molecular marker; Ia afferent; development; transgenic mice; Renshaw cell; Neurobiology; Neurobiologi; Neuroscience; Neurovetenskap;

    Sammanfattning : Movement is central for life, and all animals depend on accurate regulation of movement for purposeful behavior. There is great diversity of movements, ranging between simple and vital breathing movements to minute and subtle movements of the face used to communicate emotions. LÄS MER

  5. 24. Functional and Molecular Characterization of Centrally Expressed Genes Associated with Obesity

    Författare :Anders Eriksson; Helgi Schiöth; Christian Broberger; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroscience; Neurovetenskap;

    Sammanfattning : Obesity is a complex disorder that has reached epidemic proportions in the Western world, currently affection more than two billion people. The evidence for the genetic influence on obesity has been estimated to be as high as 70% based on twin studies. LÄS MER

  7. 25. 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.
