  1. 1. Road surface classification using near infrared spectroscopy

    Författare :Johan Casselgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : Statistics shows that most traffic accidents with fatal outcome can be related to slippery road conditions. The most hazardous road conditions are the ones that are hard for the driver to detect and that appears sudden on the road. LÄS MER

  3. 2. Brain functional near infrared spectroscopy in human infants : cerebral cortical haemodynamics coupled to neuronal activation in response to sensory stimulation

    Författare :Marco Bartocci; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Near infrared spectroscopy; newborn; infant; brain; sensory stimulation; cortical activation;

    Sammanfattning : The assessment of cortical activation in the neonatal brain is crucial in the study of brain development, as it provides precious information for how the newborn infant processes external or internal stimuli. Thus far functional studies of neonates aimed to assess cortical responses to certain external stimuli are very few, due to the lack of suitable techniques to monitor brain activity of the newborn.

  4. 3. Functioning in prosthetic users provided with and without a microprocessor-controlled prosthetic knee – relative effects on mobility, self-efficacy and attentional demand

    Författare :Saffran Möller; Nerrolyn Ramstrand; Kerstin Hagberg; David Rusaw; Catharina Sjödahl Hammarlund; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amputation; trans-femoral amputation; adaptive prosthetic knee; prosthetic limb; self-report; mobility; self-efficacy; attention; brain; gait; neuroimaging; functional near-infrared spectroscopy; cognitive load; brain activity;

    Sammanfattning : Background: To undergo a lower limb amputation is a traumatic experience affecting the individual on physical as well as psychological levels and often leading to limitations in a person´s daily life. Following an amputation individual often receive a prosthesis to address impairments in mobility and functioning. LÄS MER

  5. 4. The effect of intermittent theta-burst stimulation over the dorsomedial prefrontal cortext on brain activity in depression

    Författare :Wiebke Struckmann; Robert Bodén; Jonas Persson; Malin Gingnell; Paul Hamilton; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dorsomedial prefrontal cortex; iTBS; transcranial magnetic stimulation; Psychiatry; Psykiatri;

    Sammanfattning : Repetitive transcranial magnetic stimulation is an emerging alternative for treatment-resistant depression, with ongoing developments in stimulation protocols and treatment targets. As such, intermittent theta-burst stimulation (iTBS) delivered over the dorsomedial prefrontal cortex (dmPFC) has shown promise, however establishing a need for neuroimaging studies to further understand the treatment mechanisms.

  7. 5. Methodological aspects on carotid artery intervention

    Författare :Magnus Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :carotid artery stenosis;

    Sammanfattning : In Sweden, approximately 25000 patients suffer a cerebral infarction (stroke) annually. Stroke ranks as the third-leading cause of death, and is the leading cause of functional impairment. Carotid artery stenosis accounts for approximately 15% of all strokes and almost all of these are theoretically preventable. LÄS MER
