  1. 11. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors

    Författare :Marcus Petersson; Erik Fransén; Theodore Cummins; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion channels; computational modeling; simulations; dendrites; axons; TRP; hippocampus; C-fiber nociceptors; pain;

    Sammanfattning : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. LÄS MER

  3. 12. Spinal Cord Processing of Sensory Information: Spatial Organization and Adaptive Mechanisms

    Författare :Anders Levinsson; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; transplantatioin; pain; sensorimotor; plasticity; reflex; neuropsykologi; neurofysiologi;

    Sammanfattning : Principles for sensorimotor transformation and plasticity in the spinal cord and functional repair in the root-avulsed spinal cord were studied. A comparative study confirmed that the nociceptive withdrawal reflex (NWR) system is composed of reflex modules, with each performing a finely tuned transformation of skin sensory input to activity in one muscle.

  4. 13. Mechanisms of excitability in the central and peripheral nervous systems : Implications for epilepsy and chronic pain

    Författare :Jenny Tigerholm; Erik Fransén; Dieter Jaeger; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendritic excitability; synchronized synaptic input; multicompartment model; epilepsy; axonal excitability; silent C–fibres; Hodgkin–Huxley dynamics; conduction velocity; KA;

    Sammanfattning : The work in this thesis concerns mechanisms of excitability of neurons. Specifically, it deals with how neurons respond to input, and how their response is controlled by ion channels and other active components of the neuron. LÄS MER

  5. 14. I feel terrible! Can you measure that? : Exploring psychophysiological stress responses and their interactions with performance, subjective reports and health status

    Författare :Anna Sjörs; Torbjörn Falkmer; Björn Gerdle; Britt Larsson; Ulf Lundberg; Linköpings universitet; []
    Nyckelord :psychophysiology; motion sickness; chronic pain; stressor; performance; autonomic responses; HPA axis; MEDICINE; MEDICIN;

    Sammanfattning : Despite recent research advances, there are still several common medical conditions whose underlying mechanisms are poorly understood. In conditions with few or diffuse physical findings, it can be difficult to diagnose and determine the state of the condition and its effects on working ability or performance, and the health care practitioners have to rely on the patient’s self-reports.

  7. 15. Estrogen receptor expression in relation to pain modulation and transmission : experimental studies in rats

    Författare :Åsa Amandusson; Anders Blomqvist; Kaj Fried; Ola Hermanson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical cell biology; Medicinsk cellbiologi; Medical Cell Biology; Medicinsk cellbiologi; MEDICINE;

    Sammanfattning : Estrogens have a remarkably wide range of actions in the mammalian brain. They not only play a pivotal role in reproductive behavior and sexual differentiation, but also contribute to e.g. thermoregulation, feeding, memory, neuronal survival and the perception of somatosensory stimuli.
