  2. 6. Genetic gating of human fear, fear learning and extinction : psychophysiological, brain imaging (fMRI) and clinical studies

    Author : Tina B Lonsdorf; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Individuals differ in their reaction to the same environmental stressor. After being opposed to the same trauma, some individuals will develop affective pathologies, while others will not. This is assumed to result, at least partly, from a differential genetic vulnerability. READ MORE

  4. 7. Survival of the Tamest : The Domesticated Phenotype in Red Junglefowl Selected for Tameness

    Author : Rebecca Katajamaa; Per Jensen; Dominic Wright; Ruth C. Newberry; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; domestication; chicken; red junglefowl; tameness; brain size; behaviour; cognition; body size;

    Abstract : Early animal domestication was probably associated with reduced fear of humans. Domestication is a process in which animals adapt to humans and the captive environment provided by humans. Selection on tameness as the only trait has previously been found to generate changes in other phenotypes in different animal species. READ MORE

  5. 8. The role of aversive learning in social interactions

    Author : Tanaz Molapour; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : It could be argued that our survival as humans hinges on our ability to interact socially with others. Our social interactions are influenced by evaluations of each other: we cooperate with those we like and avoid or are aggressive towards those we dislike or are afraid of. READ MORE

  6. 9. Influence of serotonin on anxiety-like behavior in rat

    Author : Robert Pettersson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anxiety; Serotonin; SSRI;

    Abstract : It is well-established that serotonin is involved in the regulation of mood and behaviour, partly implied by the therapeutic effect of prolonged treatment with selective serotonin reuptake inhibitors (SSRI) on mood and anxiety disorders. However, the mechanisms behind the paradoxical exacerbation of anxiety described during initial treatment, as well as behind the therapeutic effects of prolonged treatment with SSRIs, remain poorly understood.

  7. 10. Brain neurotrophin levels and mouse behavior : relationship to environmental influences

    Author : Shun-Wei Zhu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Environmental Enrichment; Intermittent Individual Housing; Physical Exercise; Anxiety; NGF; BDNF; Dorsal Hippocampus; Ventral Hippocampus;

    Abstract : All normal functions over the lifetime of an animal are based on a dynamic balance of at least three fundamental elements: brain, environment and behaviour. This thesis investigated different aspects of these three elements and revealed novel interactions of brain neurotrophins, environmental influences and emotional behaviour in mice. READ MORE
