1. 1. Temporal representation of Motor Imagery : towards improved Brain-Computer Interface-based strokerehabilitation

   Författare :Jonatan Tidare; Elaine Åstrand; Pawel Herman; Mälardalens högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-computer interface; eletroencephalogram; stroke rehabilitation;

   Sammanfattning : Practicing Motor Imagery (MI) with a Brain-Computer Interface (BCI) has shown promise in promoting motor recovery in stroke patients. A BCI records a person’s brain activity and provides feedback to the person in real time, which allows the person to practice his or her brain activity. LÄS MER

3. 2. Imaging imagining actions

   Författare :CJ Olsson; Lars Nyberg; A.Mark Williams; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental training; motor training; novices; imaging; athletes; fMRI; internal imagery; motor representation; brain systems; practice; learning; transfer; active; Physiology; Fysiologi;

   Sammanfattning : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. LÄS MER

4. 3. Musik som nav i skolredovisningar

   Författare :Annika Falthin; Kungl. Musikhögskolan; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; music; presentations; social semiotic multimodality; representation; music scores; meta functions; aestethic learning; semiotic resources; musikpedagogik; noter; multimodal semiotik;

   Sammanfattning : Music as a hub in school presentationsThe aim of the study is to elucidate how making meaning is constituted when lower secondary pupils play music when giving accounts of other school subjects than music. The empirical material consists of four presenta- tions in the subjects of physics, religion and Swedish, which were filmed during ordinary lessons in a lower secondary school. LÄS MER

5. 4. The role of cortico-basal ganglia systems in the construction of movement: Action selection and sequencing

   Författare :Joel Sjöbom; Integrativ neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Electrophysiology; Voluntary movements; In-vivo; Motor Cortex; Corticostriatal; Basal Ganglia;

   Sammanfattning : The cortico-basal ganglia system is instrumental in the construction of movement, through its involvement in aspects such as action selection, initiation/termination and sequencing, though the precise role of the different structures and how they collaborate on a network level to allow us to fluidly change from one behavior to another has long proven to be elusive.We have here recorded neuronal activity throughout the cortico-basal ganglia circuit in rats, in a series of projects in order to understand more about how some of these functions are controlled.

7. 5. 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.
