  1. 1. Investigations of neural attractor dynamics in human visual awareness

    Author : David N. Silverstein; Pawel Herman; Martin Ingvar; Karl Friston; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; attractor dynamics; visual awareness; visual perception; visual attention; attentional blink; backward masking; gliomas; brain tumor; white matter; cell assemblies; neocortical model; threat response; fear signaling; amygdala; Biological Physics; Biologisk fysik; Computer Science; Datalogi; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : What we see, how we see it and what emotions may arise from stimuli has long been studied by philosophers, psychologists, medical doctors and neuroscientists. This thesis work investigates a particular view on the possible dynamics, utilizing computational models of spiking neural attractor networks. READ MORE

  2. 2. Children with visual disorders : cognitive development, developmental disorders and consequences for treatment and counselling

    Author : Ulla Ek; Michael Brambring; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; visually impaired; children; development; developmental disorders; assessment; Psychology; Psykologi; psykologi; Psychology;

    Abstract : The causes of visual impairment and blindness has changed over the years, in Sweden and in other industrialised countries, giving rise to a new population of visually impaired children. Damages to the posterior visual pathway and the brain are now common causes of visual impairment. READ MORE

  3. 3. On visual impairment in Swedish children

    Author : Jonas Blohmé; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; Sweden; sociology; mortality; outcome; epidemiology; registration; childhood blindness; Visual impairment; children; Oftalmologi;

    Abstract : Knowledge of the epidemiology of visual impairment in children forms one of the cornerstones in paediatric ophthalmology. To gain an overview of the situation in Sweden an epidemiological study was performed. Totally 2373 visually impaired children were found, giving an age-specific prevalence of 10,9/10 000. Childhood blindness (i. READ MORE

  4. 4. Visual and tactile neglect

    Author : Haukur Hjaltason; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Improving roundabouts for cyclists and visually impaired

    Author : Lisa Sakshaug; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accessibility; safety; visually impaired; cyclist; roundabout;

    Abstract : Roundabouts are continuing to increase due to their high traffic safety, low delay times and their winning design. However, there are also problems related to roundabouts; the traffic safety for cyclists is unclear or even negative and there are reports of accessibility problems for people with visual impairment.
