  2. 6. Sensorimotor function following anterior cruciate ligament injury : movement control, proprioception and neuropsychological perspectives

    Author : Adam Grinberg; Charlotte Häger; Martin Björklund; Dario G. Liebermann; Clare Ardern; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ACL; knee injury; sensorimotor control; proprioception; functional test; fear; anxiety; kinematics; electromyography; EMG; electroencephalography; EEG; brain; neuroplasticity; injury prevention; Sports Medicine; idrottsmedicin;

    Abstract : Background: The high incidence of anterior cruciate ligament (ACL) injuries in sports suggests an involvement of both biomechanical and neurocognitive risk factors. Athletes are constantly exposed to challenging sports scenarios, which are often characterised by high-intensity movements combined with a multi-stimuli environment and continuous psychological pressure.

  4. 7. Inflammation and Cell Profileration Following Perinatal Brain Injury

    Author : Katarina Järlestedt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia-ischemia; immature brain; reactive gliosis; complement system; C3a; fear conditioning; lipopolysaccharide; inflammation;

    Abstract : Inflammation plays an important role in cerebral ischemic injury in the immature brain. The aim of the thesis was to investigate (1) the role of astrocyte activation and reactive gliosis in neonatal hypoxic-ischemic (HI) brain injury, (2) the role of complement derived peptide C3a in neonatal HI brain injury, (3) the effect of neonatal HI brain injury on fear learning and behaviour, (4) the effects of lipopolysaccharide (LPS) induced systemic inflammation on cell proliferation in the developing brain.

  5. 8. Learning not to fear : extinction, erasure, and the recovery of fear memories

    Author : Armita Golkar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Much of the progress in understanding the mechanisms underlying the formation and persistence of fear memories comes from studies of Pavlovian conditioning and extinction. Recently, considerable interest has been turn to strategies that facilitate the development and persistence of extinction. READ MORE

  6. 9. Behavior and cytogenesis following irradiation or isoflurane exposure to the developing brain

    Author : Niklas Karlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; isoflurane; anesthesia; hippocampus; neurogenesis; memory; learning; intellicage; dentate gyrus; trace fear conditioning; open field; object recognition;

    Abstract : In this thesis, the effects of an anesthetic agent, isoflurane, on the young brain and resulting behavioral effects were investigated. Anesthesia is commonly used in young children during surgery or other procedures associated with pain or discomfort. READ MORE

  7. 10. Genetic gating of human fear, fear learning and extinction : psychophysiological, brain imaging (fMRI) and clinical studies

    Author : Tina B Lonsdorf; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Individuals differ in their reaction to the same environmental stressor. After being opposed to the same trauma, some individuals will develop affective pathologies, while others will not. This is assumed to result, at least partly, from a differential genetic vulnerability. READ MORE
