  1. 1. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Författare :Aravin Chakravarthi; Funktionell zoologi; []
    Nyckelord :Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Sammanfattning : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. LÄS MER

  3. 2. Functional mapping of somatosensory cortices in the human brain

    Författare :Anna S K Bodegård; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sornatosensory areas; PET; cytoarchitectonic mapping; postcentral gyrus; shape perception; active touch; passive touch;

    Sammanfattning : Tactile perception is a remarkable ability that enables us to recognise objects and handle tools. Cortical processing during tactile and shape perception in humans is not fully understood. LÄS MER

  4. 3. Intergroup Relations : When is My Group More Important than Yours?

    Författare :Luisa Batalha; Bo Ekehammar; Henry Montgomery; Uppsala universitet; []

Research has, however, shown that outgroup favouritism, that is, the preference for a group to which the person does not belong, also permeates intergroup relations. LÄS MER

  5. 4. Från diversity management till mångfaldsplaner? Om mångfaldsidéns spridning i Sverige och Malmö stad

  7. 5. Imaging vision : functional mapping of intermediate visual processes in man

    Författare :Jonas Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human visual system is highly adept at recognizing objects independent of changes in viewing conditions, such as viewpoint, illumination, and partial occlusions by other objects in the visual environment. This invariance to viewing conditions is believed to be achieved by generating invariant shape representations from the variable visual input. LÄS MER
