    Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias.

  3. 2. Individual Differences in Multitasking : Support for Spatiotemporal Offloading

    Författare :Ivo Todorov; Timo Mäntylä; Fredrik Jönsson; Patrik Sörqvist; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; multitasking; cognitive offloading; cognitive functions; individual differences; executive functions; spatial ability; sex differences; Psychology; psykologi;

    Sammanfattning : In both the private and work spheres, multitasking among three or more activities has become and is continuing to evolve as a pervasive element of everyday life, and recent technological advances only seem to be exacerbating the process. Despite attempts to understand the mental processes that let humans successfully multitask, little is known about the functional cognitive level at which these mental processes take place. LÄS MER

  4. 3. Sex differences in immune response and sex hormone receptor expression in healthy individuals and during viral infection

    Sammanfattning : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. LÄS MER

  5. 4. Sex differences in children's play behavior : A biological construction of gender?

    Författare :Anna Servin; Uppsala universitet; []

    Sammanfattning : The present thesis addressed the question of what causes sex differences in children's play behavior.In Study I, it was found that mothers have rather sex-stereotyped expectations for how their 1- and 3-year-old children will behave at the age of five, as regards sex-typed activities.

  7. 5. Stroke, Sex and Vascular Receptor Changes in the Brain

    Författare :Hilda Ahnstedt; Lund Medicin; []

    Sammanfattning : Stroke is a severe cerebrovascular disease in which the neuronal tissue and vasculature of the brain undergo ischemia-evoked alterations. We have demonstrated an increased expression of cerebrovascular contractile receptors in the brain. This is hypothesized to mitigate cerebral blood flow and exacerbate tissue damage after stroke.
