  1. 1. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Författare :Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. LÄS MER

  2. 2. Factors influencing nerve growth in situ and in vitro

    Författare :Helena Jerregård; Mårten Risling; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Bakgranden till denna doktorsavhaodling är den problematik som uppstår efter en perifer nervskada, roreträdesvis i relation till handen eftersom den har så stor betydelse i vårt dagliga liv. En haod utan känsel fungerar dåligt och än sänne fungerar en handprotes. LÄS MER

  3. 3. 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. 4. Tendon autografts for bridging nerve defects

    Författare :Jerker Brandt; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Surgery; orthopaedics; cell culture; graft; rat; collagen; tendon; Schwann cells; axons; Peripheral nerve regeneration; axonal outgrowth; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : A new method, where a tendon segment – a tendon autograft – was used as graft material for peripheral nerve reconstruction, was developed. Defects, 10-15 mm long, in rat sciatic nerves were bridged by various modifications of tendons. LÄS MER

  5. 5. The role of the MAP- and SAP- kinase pathways in the survival, proliferation and death of Schwann cells of the injured sciatic nerve

    Författare :Lisa Mårtensson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns alterations in signal transduction in Schwann cells as a response to nerve injury as well as their survival, proliferation and death. Enzymes and transcription factors belonging to the mitogen activated protein kinase (MAPK) and the stress activated protein kinase (SAPK) pathways were studied. LÄS MER
