  3. 7. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

    Författare :Alexander Olsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; Machine Learning; Deep Learning; Feature Learning; Biosignal Processing; Gesture Recognition; Muscle-Computer Interfaces; Myoelectric Control; Upper-Limb Prosthetics;

    Sammanfattning : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

  4. 8. Neural Stem Cells - interaction with the brain and prospects for cell replacement therapy for Stroke

    Författare :Emanuela Monni; Neural stamcellsbiologi och terapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neural stem cells; human; fetus; cortex; striatum; stroke; transplantation; inflammation; fusion; reprogramming; chimera; heterokaryon;

    Sammanfattning : Stroke is an acute neurological condition and the leading cause of disability in adult humans. Treatments for efficient recovery are not available. The most common form of stroke results from the occlusion of the middle cerebral artery, which causes loss of brain parenchyma and many types of neurons as well as astrocytes and oligodendrocytes.

  5. 9. The Human Spiral Ganglion

    Författare :Sven Tylstedt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. LÄS MER

  7. 10. Structure and dynamics of amyloid-beta oligomers

    Sammanfattning : Alzheimer's disease (AD) is the most common cause of dementia, affects tens of millions of people all over the world and inflicts huge socioeconomic costs on the societies. AD is a neurodegenerative disease; it progresses over time and is highly debilitating at the advanced stages. LÄS MER
