    Sammanfattning : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. LÄS MER

  3. 2. Textile electrodes for ECG measurements in distributed care, performance and applications

    Författare :Linda Rattfält; Per Ask; Peter Hult; Maria Lindén; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of this thesis work has been to explore textile electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to noise with signal processing techniques. Previous research within the field has shown that acquisition of ECG is possible with textile electrodes, but little attention has been focused on how they function and especially if movements are included in the measurement protocol.

  4. 3. Neurons and glia in the peripheral nervous system : interactions in health and disease

    Författare :Filipa Bouçanova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The peripheral nervous system (PNS) is composed of nerves and ganglia that connect the brain and the spinal cord (the central nervous system, CNS) to the outside world. The nerves contain the extensions (axons) of both sensory and motor neurons, which allow us to detect and respond to different stimuli. LÄS MER
