  1. 21. Gaze control in episodic memory

    Author : Linus Holm; Timo Mäntylä; Bruno Laeng; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi; Psychology; psykologi;

    Abstract : The role of gaze control in episodic recognition was investigated in two studies. In Study 1, participants encoded human faces inverted or upright, with or without eye movements (Experiment 1) and under sorting or rating tasks (Experiment 2) respectively. READ MORE

  2. 22. When, Where and What : The Development of Perceived Spatio-Temporal Continuity

    Author : Olga Kochukhova; Claes Von Hofsten; Richard Aslin; Uppsala universitet; []
    Keywords : Psychology; infants; occlusion; incomplete visual information; saccadic gaze shifts; smooth pursuit; temporal; spatial; object representation; learning; extrapolation; Psykologi;

    Abstract : This thesis explored the development of infants’ ability to preserve spatio-temporal continuity of moving objects in situations where they disappeared completely (Study I & II) or partially (Study III) behind other objects (occluders). We recorded infants gaze direction with the help of two different techniques: 1) infants’ gaze shifts in Study I were measured with electro-oculogram (EOG) in combination with a motion analyzing system (Qualisys) that recorded the reflected infrared light from markers placed on the infant’s head and the moving object; 2) in Studies II and III a cornea reflection eye tracker was used (Tobii 1750) .

  3. 23. Subarachnoid Hemorrhage in the Elderly

    Author : Mats Ryttlefors; Per Enblad; Kristina Cesarini; David Mendelow; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid hemorrhage; intracranial aneurysm; elderly; outcome; endovascular coiling; neurosurgical clipping; secondary insult; cerebral vasospasm; Neurosurgery; Neurokirurgi;

    Abstract : Subarachnoid hemorrhage (SAH) is a disease with high risk of mortality and morbidity. Elderly patients have an even higher risk of poor outcome. The incidence of SAH increases with age and the elderly constitute a substantial and increasing proportion of the population. Thus, the management of elderly SAH patients is an imminent clinical challenge. READ MORE

  4. 24. Popliteal Artery Aneurysms : - epidemiology, treatment and results

    Author : Anne Cervin; Martin Björck; Mårten Falkenberg; Hans Ravn; Michelle Antonello; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Popliteal artery aneurysms; Endovascular; Open surgery; Outcome; Occlusion; Screening; Prevalence; Rupture; Surgery; Kirurgi;

    Abstract : Popliteal aneurysms (PA) are limb threatening, since the aneurysm thrombose and emboli from the aneurysm sac occlude the distal vessels, resulting in chronic or acute limb ischaemia. Open surgical repair (OSR) has been challenged by endovascular repair (ER), a minimal invasive technique. READ MORE

  5. 25. Ventricular rotation and the rotation axis : a new concept in cardiac function

    Author : Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

    Abstract : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. READ MORE
