  1. 1. Functional organization of spinal nociceptive pathways: evidence for a modular organization of spinal nociceptive reflex systems

    Detta är en avhandling från Department of Physiology and Neuroscience, Lund University

    Författare :Han-Rong Weng; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; electromyography.; spinal cord; hyperreflexia; neural plasticity; spinal injuries; receptive fields; inhibitory mechanisms; motor control; flexion reflex; interneurones; Neurologi; sensorimotor integration; somatosensory; analgesia; pain; nociception; neuropsykologi; neurofysiologi;

    Sammanfattning : The functional organization of the hindlimb withdrawal reflex system was studied in the rat. For the reflex pathway to each muscle, a "mirror-image" relationship was found between the spatial distribution of sensitivity within its cutaneous receptive field and the pattern of cutaneous unloading ensuing on muscle contraction.

  2. 2. Monoaminergic modulation in spinal reflex pathways from group I afferents

    Detta är en avhandling från Göteborg

    Författare :Ingela Hammar; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; primary afferents; spinal interneurones; ventral spinocerebellar tract neurones; noradrenaline; serotonin; cat;

    Sammanfattning : Serotonin and noradrenaline are known to play an important part in modulation of spinal neuronal networks. Group I muscle afferents mediate information on dynamic changes of muscle length and tension, and modulation of actions from these afferents could be of importance for the execution of movements.

  3. 3. Neuronal networks involved in low back pain; experimental studies

    Detta är en avhandling från Göteborg

    Författare :Elin Nilsson; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low back pain; disc herniation; pyramidal tract; reticulospinal tract; longissimus muscle; nucleus pulposus; VPL; thalamus; rat; cat;

    Sammanfattning : Low back pain is a common cause of disability, with a lifetime prevalence of up to 80%. A lumbar disc herniation, involving a bulging disc and/or leakage of the intervertebral disc’s nucleus pulposus, may be a possible cause of back and sciatic pain. Low back pain has also been associated with dysfunctional control of the paraspinal muscles. LÄS MER

  4. 4. NO PAIN, STILL GAIN- cross-modality development learning guided by spinal spontaneous activity

    Detta är en avhandling från Alexandra Waldenström, Dept. of Physiological Sciences, Sect. for Neurophysiology, BMC F10, S-221 84 Lund, Sweden

    Författare :Alexandra Waldenström Ellervik; Lunds universitet.; Lund University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; Neurologi; Neurology; neuropsychology; development; spinal cord; activity-dependent learning and memory; pain; somatosensory; neurophysiology;

    Sammanfattning : Popular Abstract in Swedish Smärta är en varningssignal vid vävnadskada. En speciell grupp av receptorer i huden är känsliga för skadlig stimulering och kallas för nociceptorer. Signalerna från dessa ”smärtreceptorer” leds via två fibertyper till ryggmärgen. Beröringssignaler förmedlas via andra typer. LÄS MER

  5. 5. Modulation of pain by immune factors : A study on interferon-g and its receptor in nociceptive transmission

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Neuroscience

    Författare :Kristina S Vikman; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytokines; interferon-gamma; dorsal horn; hypersensitivity; nociceptive transmission; pain; GluR1; AMPA receptor; disinhibition; spontaneous activity; primary cell culture; two-compartment model; spinal cord.;

    Sammanfattning : Immune cytokines have been implicated as important neuromodulators, contributing to neuronal plasticity both in the adult and developing nervous system. In addition, they have been assigned a potential role in the generation of pathological pain, which may occur as a severe symptom following disease states in the nervous system. LÄS MER
