2. 1. Olfactory Function : The Influence of Demographic, Cognitive, and Genetic Factors

   Author : Margareta Hedner; Maria Larsson; Lars-Göran Nilsson; Claire Murphy; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; odor identification; odor threshold; odor discrimination; aging; gender; ApoE; BDNF; val66met; association study; population-based; Psychology; psykologi;

   Abstract : Olfactory function is affected by demographic, cognitive, and genetic factors. In the present thesis, three empirical studies investigated individual differences in olfactory ability. Study I explored demographic and cognitive correlates in common olfactory tasks; odor detection, odor discrimination, and odor identification. READ MORE

4. 2. BDNF, impulsiveness and avoidant focused coping in suicide attempters

   Author : LIVIA AMBRUS; Lund Psykiatri; []
   Keywords : BDNF; Aviodant coping; Suicide Attempters; HPA axis; Impulsvieness; BDNF; Avoidant focused coping; HPA axis; attempted suicide; impulsiveness;

   Abstract : Brain-derived neurotrophic factor (BDNF) is an important protein for neuroplasticity and neurogenesis. In this thesis the role of BDNF, in suicidal behaviour was investigated with focus on possible risk factors for suicidal behaviour such as avoidant focused coping, dysfuntional personality traits like impulsiveness and hyperactivity of the Hypothalamic-Pituitary-Adrenal (HPA) axis.

6. 4. On the influence of dopamine-related genetic variation on dopamine-related disorders

   Author : Olle Bergman; Göteborgs universitet; []
   Keywords : dopamine; neurodevelopment; amygdala; schizophrenia; Parkinson s disease; social anxiety disorder; ADHD; PITX3; LMX1A; LMX1B; BDNF; DAT; SNP; genes; genetics; BDNF;

   Abstract : Rationale: Dopamine synthesizing neurons are involved in a wide variety of functions. The most prominent dopamine pathways originate in the midbrain. The development, function and survival of these dopaminergic neurons are under the influence of numerous transcription and neurotrophic factors. READ MORE

7. 5. On the influence of serotonin- and sex steroid-related genetic variation on mood, anxiety, personality, autism and transsexualism

   Author : Susanne Henningsson; Göteborgs universitet; []
   Keywords : serotonin; 5-HTTLPR; TPH2; 5-HT3; sex steroids; androgen receptor; estrogen receptor; genetics; gene-gene interaction; social phobia; anxiety; premenstrual dysphoric disorder; depression; personality; autism; transsexualism; amygdala; emotional perception; life events;

   Abstract : Background: The neurotransmitter serotonin has been related to mood and anxiety, and variation in genes that encode important members of the serotonergic system may hence affect mood- and anxiety-related traits. Sex steroids influence brain development, and variation in genes encoding androgen and estrogen receptors, or enzymes needed for sex steroid synthesis, may be of importance for both personality traits and risk for psychiatric disorders.
