  1. 26. Cognitive functioning in late senescence : influences of age and health

    Författare :Tarja-Brita Robins Wahlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cognitive functioning; aging; health; individual differences;

    Sammanfattning : The overall aim of this doctoral thesis was to investigate potential age-related differences between groups of healthy very old adults from 75 to 96 years of age in various cognitive functions. An additional objective was to examine the influence of individual-difference variables within demographic (e.g., education, gender), psychometric (e. LÄS MER

  3. 27. Psychobiological 24-hour patterns : theory, methods and summary of empirical studies

    Författare :Jan E. Fröberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The principal aim of this work was to study the characteristics of 24-hour patterns in various performance functions, in subjective wakefulness, and in physiological variables-their temporal interrelationships and correlation with individual habits. Human subjects were isolated in groups under controlled conditions, and were deprived of sleep for 72 hours. LÄS MER

  4. 28. The neural mechanisms of selective attention : Investigation of insect selective attention during visual object tracking using neurophysiology, neuroanatomy, computational modelling

    Författare :Bo Bekkouche; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The brain simulates the world around us using sensory information and provides an estimation of reality in which actions can be executed. This estimation of reality is controlled by attention which decides which information is accepted, further processed and ignored. LÄS MER

  5. 29. Short- and long-term neuronal plasticity in hippocampal CA1 region of rat

    Författare :Fen-Sheng Huang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glutamate; hippocampus; plasticity; synapse; LTP; LTD; AMPA; NMDA;

    Sammanfattning : The brain is highly plastic, displaying both short- and long-term changes, resulting from developmental processes as well as learning and memory. Moreover, short-term plasticity such as paired pulse facilitation and depression (PPF, PPD) have long been used to monitor the presynaptic versus postsynaptic changes occurring during more lasting processes such as long-term potentiation and depression (LTP, LTD).

  7. 30. Exploring the Hidden Dimensions of Distraction in Adults with Atypical Attention

    Författare :Pia Elbe; Jessica Körning-Ljungberg; Daniel Sörman; Mariana Vega Mendoza; Lars Nyberg; Henrik Danielsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; distraction; ADHD; cognition; Psychology; Psykologi;

    Sammanfattning : Inattention and proclivity for distraction are symptoms of adult ADHD that hamper productivity in study and work environments. The topic of this dissertation is mechanisms of distraction and facilitation of attention in ADHD. This thesis includes three studies. LÄS MER
