  1. 16. Exploring models of time processing : effects of training and modality, and the relationship with cognition in rhythmic motor tasks

    Författare :Olympia Karampela; Guy Madison; Linus Holm; Fredrik Ullén; Simon Grondin; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; timing; motor timing; cogntion; dedicated models; intrinsic models; timing variability;

    Sammanfattning : Timing can be defined as the ability to perceive temporal sequences and regulate timed behaviors. As in other animals, our ability to make accurate time estimations is crucial in order to accomplish several activities. Organisms can process time over a wide range of durations ranging from microseconds to days. LÄS MER

  4. 18. Visual and tactile neglect

    Författare :Haukur Hjaltason; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Visual neglect; tactile neglect; premotor neglect; perceptual neglect; bisection tasks; darkness; tactile exploration; right hand use; right hemisphere activation; three-dimensionality; figure-ground contrast; chronic;

    Sammanfattning : Neglect patients typically fail to report, respond, or orient to information presented in locations further away from the side of the brain lesion. Neglect is most often reported after acute stroke, and is more severe and more frequent after right hemisphere damage. LÄS MER

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Natural economic orders are made and unmade. Industries such as telecommunications, rail transportation, and electricity distribution are prime examples. In the last two decades we have witnessed the widespread unmaking of these long established public natural monopolies. LÄS MER

  7. 20. Anterior Cruciate Ligament injury, Patient Variables, Outcomes and Knee Osteoarthritis

    Författare :Paul Neuman; Enheten för led- och mjukvävnadsforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; meniscal injury; knee osteoarthritis; knee radiography; Anterior cruciate ligament injury ACL ; delayed gadolinium-enhanced MRI of cartilage dGEMRIC ;

    Sammanfattning : The ruptured anterior cruciate ligament (ACL) leads to immediate symptoms that severely affect the individual and receives great attention among the scientific community, yet there is still no consensus on the optional form of treatment. An ACL injury is also a well known high risk factor for the development of knee osteoarthritis (OA) some decades later. LÄS MER
