  1. 1. On the Site of the Lesion in Konzo : Clinical and Neurophysiological Studies on a Non-Progressive Upper Motor Neuron Disorder

    Författare :Desire Tshala-Katumbay; Andrew Eisen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Konzo; upper motor neuron diseases; WHO criteria; electroencephalography; evoked potentials; brain involvement; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Konzo is a permanent spastic para/tetraparesis occurring in undernourished populations in Africa relying on insufficiently processed bitter cassava, which contains cyanogenic compounds, as staple food. Its pathogenetic mechanism is unknown. Our studies aimed at clarifying the lesion in konzo. LÄS MER

  2. 2. Non-invasive Functional Neuroimaging for Localizing Epileptic Brain Activity

    Författare :Yazdan Shirvany; Chalmers University of Technology; []
    Nyckelord :Mathematical Dipole; Finite Element Method; Source localization; Structural Magnetic Resonance Imaging; Forward Problem; Inverse Problem; Particle Swarm Optimization; Non-invasive EEG; Somatosensory Evoked Potentials; Epileptic Spike; Functional Neuroimaging;

    Sammanfattning : Surgical therapy has become an important therapeutic alternative for patients with medically intractable epilepsy. Correct and anatomically precise localization of the epileptic focus, preferably with non-invasive methods, is the main goal of the pre-surgical epilepsy diagnosis to decide if resection of brain tissue is possible.

  3. 3. Non-invasive EEG Functional Neuroimaging for Localizing Epileptic Brain Activity

    Författare :Yazdan Shirvany; Chalmers University of Technology; []
    Nyckelord :Somatosensory Evoked Potentials; Forward Problem; Inverse Problem; Mathematical Dipole; Epileptic Spike; Functional Neuroimaging; Structural Magnetic Resonance Imaging; Particle Swarm Optimization; Source localization; Finite Element Method; Non-invasive EEG;

    Sammanfattning : Epilepsy is one of the most common neurologic diseases in the world, and is present in up to 1% of the world’s population. Many patients with epilepsy never receive the treatment which make them seizure free. Surgical therapy has become an important therapeutic alternative for patients with drug resistant epilepsy.

  4. 4. Plasticity in mice nociceptive spinal circuits -role of cell adhesion molecules

    Författare :Jonas Thelin; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long term-potentiation; Cell adhesion molecule; Pain; Somatosensory imprinting; Medicin människa och djur ; Medicine human and vertebrates ; Nociceptive withdrawal reflex; Species differences; Central sensitisation; Mouse strains; Spinal cord;

    Sammanfattning : Introduction: To understand the function of the genes and their products in the pain system, studies will have to deal with complex issues related to intercellular communication, e.g. plasticity in neuronal networks. LÄS MER

  5. 5. Spotting pain in the brain. Towards a useful animal model of pain

    Författare :Tanja Jensen; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analgesics; freely moving rat; microelectrode; Nociception; Primary somatosensory cortex; Sedatives;

    Sammanfattning : Current models of pain in conscious animals usually scores nocifensive responses. However, it is still unclear to what extent these responses are related to, for instance, the sensory discriminative or affective aspects of pain. LÄS MER
