  1. 1. Comparative Analysis of Transformer and CNN Based Models for 2D Brain Tumor Segmentation

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Henrik Träff; [2023]
    Nyckelord :Machine Learning; ML; AI; Computer vision; Vision Transformer; Swin Transformer; U-Net; nnU-Net; Brain Tumor Segmentation; Deep Learning;

    Sammanfattning : A brain tumor is an abnormal growth of cells within the brain, which can be categorized into primary and secondary tumor types. The most common type of primary tumors in adults are gliomas, which can be further classified into high-grade gliomas (HGGs) and low-grade gliomas (LGGs). LÄS MER

  3. 2. The neural correlates of cognitive reappraisal among post-traumatic stress disorder patients : A systematic review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Cecilia Nordin; Cecilia Mattsson; [2023]
    Nyckelord :Emotion regulation; post-traumatic stress disorder; cognitive reappraisal; neural correlates; functional magnetic resonance imaging;

    Sammanfattning : The ability to regulate emotions is essential for human well-being. Among posttraumatic stress disorder (PTSD) patients, the capability to control emotions is impaired. Trauma-focused cognitive behavioral therapy is a recommended treatment for patients diagnosed with PTSD. LÄS MER

  4. 3. The Evil Inside : A Systematic Review of Structural Differences in Psychopathy

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Diana Rehn Åstrand; Julia Vedin; [2023]
    Nyckelord :psychopathy; PCL-R; structural neuroimaging; prefrontal cortex;

    Sammanfattning : The purpose of this systematic review was to characterize further the structural differences in the prefrontal cortex, limbic and paralimbic regions and amygdala alone in psychopaths. Psychopathy is a multifaceted personality disorder characterized by interpersonal and affective traits like lack of empathy, guilt or remorse, shallow affect, and carelessness, as well as behavioral traits such as impulsivity, and poor behavioral control.

  5. 4. Structural and Functional Brain Changes due to Pregnancy and Early Postpartum Period: A Systematic Review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Sanne Lövgren; [2022]
    Nyckelord :pregnancy; brain; structural; functional;

    Sammanfattning : A big part of the female population experience pregnancy and giving birth. Evidence from animal studies indicates numerous adaptations in the brain throughout pregnancy and the postpartum period. The effects on the human brain are not as well studied, which is problematic due to the complexity of comparing species. LÄS MER

  7. 5. Magnetresonanstomografi eller ultraljud- ett komplement till undersökning av täta bröst : En allmän litteraturöversikt

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Katayoun Hosseini; Anita Jankovic; [2021]
