  1. 11. Neuronal types and their specification dynamics in the autonomic nervous system

    Författare :Alessandro Furlan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The autonomic nervous system is formed by a sympathetic and a parasympathetic division that have complementary roles in the maintenance of body homeostasis. Autonomic neurons, also known as visceral motor neurons, are tonically active and innervate virtually every organ in our body. LÄS MER

  3. 12. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Författare :Karin Rylander; Göteborgs universitet; []
    Nyckelord :CT afferent; thin fibre; autonomic; insula; fMRI;

    Sammanfattning : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. LÄS MER

  4. 13. Gastrointestinal disturbances in hereditary transthyretin amyloidosis

    Sammanfattning : BackgroundTransthyretin amyloid (ATTR) amyloidosis is a systemic disorder caused by amyloid deposits formed by misfolded transthyretin (TTR) monomers. Two main forms exist – wild-type and hereditary ATTR amyloidosis, the latter associated with TTR gene mutations. LÄS MER

  5. 14. Pregnancy—A Critical Time for Mental Health : Interrogating Psychiatry with Microbiota-Gut-Brain Axis and Autonomic Nervous System Biomarkers

    Sammanfattning : Perinatal mood and anxiety disorders (PMADs) are common and impact the parent and child beyond the perinatal period of pregnancy and postpartum. The aim of this thesis was to study biomarkers that might reflect perinatal mental health. LÄS MER

  7. 15. Psycho-physiological reactions to violent video gaming : Experimental studies of heart rate variability, cortisol, sleep and emotional reactions in teenage boys

    Författare :Malena Ivarsson; Lennart Högman; Frank Lindblad; Staffan Janson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; video gaming; media violence; autonomic nervous system; heart rate variability; HPA axis; cortisol; sleep quality; emotional reactions; desensitization; teenagers; Psychology; psykologi;

    Sammanfattning : Playing violent video games may provoke aggression. Psycho-physiological methods may provide knowledge about the underlying psychological processes. Most previous studies have been performed in laboratory settings at daytime with adults. LÄS MER
