11. Genetic and experimental studies of seasonal affective disorder and related phenotypes
Sammanfattning : Seasonal affective disorder (SAD) is a subtype of recurrent depressive or bipolar disorder, in which episodes reoccur and remit during a particular season each year. A genetic component in vulnerability to winter SAD has been suggested, and the goal of this thesis was to increase the understanding of SAD and seasonal variations in mood, by obtaining self-report assessments of related traits, examining genetic variations in genes hypothesised to influence the phenotypes in question, and to investigate effects of different photoperiods and stress in an animal model.

12. Modulation of hippocampal gamma oscillations by dopamine and serotonin receptor subtypes
Sammanfattning : Normal brain function is dependent on the efficient and effective communication between the multitudes of microcircuits that it encompasses. The brain employs neuronal-network oscillations for large-scale communication in the cortex. LÄS MER
13. Pathological Internet use and psychopathology among European adolescents
Sammanfattning : Background: Internet use and accessibility has grown exponentially across the globe. The highest rates are noted in adolescents and youth. The swift development of technological improvements combined with interactive and enticing online activities has demonstrated to be unprecedented. LÄS MER
14. Receptor-ligand interactions of the human 5-HT1B receptor : A site-directed mutagenesis study
Sammanfattning : The 5-hydroxytryptamine (5-HT, serotonin)1B receptor is one of thirteen G protein-coupled 5-HT receptors. 5-HT is known to influence temperature regulation, pain, cognition and sexual and feeding behaviours. LÄS MER
15. Dynorphin A – Interactions with receptors and the membrane bilayer
Sammanfattning : The work presented in this thesis concerns the dynorphin neuropeptides, and dynorphin A (DynA) in particular. DynA belongs to the wider class of typical opioid peptides that, together with the opioid receptors, a four-membered family of GPCR membrane proteins, form the opioid system. LÄS MER
