  1. 11. Neuronal tracers for fine caliber spinal primary afferents and their response to peripheral nerve injury

    Författare :H Fredrik Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Rat; Primary afferents; Dorsal root ganglion; Peripheral nerve injury; Spinal cord; Isolectin GSA I-B4; Soybean agglutinin; Cholera toxin B subunit; Horseradish peroxidase; Immunohistochemistry; Neuronal tracing;

    Sammanfattning : The isolectin B4 from Griffonia simplicifolia I (B4) and soybean agglutinin from the plant Glycine max (SBA), have been shown to bind to rat small-diameter dorsal root ganglion (DRG) neurons, and to fibers and presumed terminals in laminae I-II of the spinal cord dorsal horn. In the present thesis, these lectins and/or their horseradish peroxidase (HRP) conjugates, have been investigated in the rat with regard to their usefulness as selective neuronal markers of and axonally transported tracers for somatic and/or visceral spinal primary afferents with fine caliber, including unmyelinated, axons.

  3. 12. Changes in sensory systems during aging : an experimental study in the rat

    Författare :Esbjörn Bergman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :aging; behavior; primary sensory neuron; dorsal root ganglion; mystacial pad; sensory nerve ending; axon dystrophy; neuropeptides; B4; RT97; CTB; neurotrophins; trk; p75NTR; GFR[alpha]; RET; protein; mRNA;

    Sammanfattning : Aging is associated with sensorimotor disturbances, including increased proprioceptive thresholds. The present study aimed to clarify the occurrence of structural and biochemical alterations in sensory systems of behaviorally characterized aged rats. LÄS MER

  4. 13. 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.

  5. 14. Central projections of sensory innervation of cranial vessels

    Författare :Yi Liu; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; Spinothalamic; Neurology; neuropsychology; neurophysiology; Neural tracing; trigeminal nerve; Headache; Cranial vessel; Brainstem; neuropsykologi; neurofysiologi;

    Sammanfattning : Primary headaches (e.g. migraine and cluster headache), the symptoms of which is associated with cranial vascular activity, is likely to be dependent on a primary central nervous system dysfunction. LÄS MER

  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.
