  1. 6. Appetite-regulating peptides and natural rewards: emphasis on ghrelin and glucagon-like peptide-1

    Författare :Jesper Vestlund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Reward; Gut-brain axis; Sexual behaviors; Skilled reach foraging;

    Sammanfattning : Evolutionary conserved natural behaviors, such as foraging and sexual behaviors, are strongly associated with reward processes. Brain areas important for reward processes include, but are not limited to, the nucleus accumbens (NAc) shell, the ventral tegmental area (VTA), the laterodorsal tegmental area (LDTg) and the nucleus of the solitary tract (NTS).

  3. 7. Glucagon-like peptide-1 and alcohol-mediated behaviors in rodents

    Författare :Daniel Vallöf; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; Dopamine; Gut-brain axis; Reward;

    Sammanfattning : Alcohol use disorder (AUD) is a serious cause of morbidity and mortality. However, due to the limited efficacy of existing pharmacotherapies, further investigations of potential neurochemical targets are required to define new pharmacological interventions. LÄS MER

  4. 8. Hedonic, neural, and autonomic responses to prolonged gentle touch

    Författare :Chantal Triscoli; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; long-lasting touch; CT afferents; pleasantness; liking; wanting; satiety; orbitofrontal cortex; reward; heart rate variability;

    Sammanfattning : Physical contact among individuals, such as caressing and cuddling, is connoted by a strong emotional value, and is usually perceived as a pleasant and rewarding experience. C tactile (CT) afferents are a class of fibres that are specific channels for detecting touch at a caress-like veloc-ity (between 1 and 10 cm/s). LÄS MER

  5. 9. Taste Hedonics and the Intake of Alcohol and Food

    Författare :Anna Söderpalm; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Alcohol drinking; Adrenalectomy; Corticosterone; Cyanoketone; Food intake; Food restriction; GABA; Metyrapone; Taste reactivity; Benzodiazepine; Chlordiazepoxide; Cis Z -flupentixol; Diazepam; Flumazenil; Microinjections; Midazolam; Nucleus of the Solitary tract; Palatability; Parabrachial nucleus; Peduculopontine Tegmental Nucleus; Reward; 4th ventricle.;

    Sammanfattning : This thesis includes four papers based on animal experimental work. They analyze the way in which activation of a specific motivational state - hunger- modulates the rewarding actions of alcohol and taste palatability. LÄS MER

  7. 10. On cholinergic mechanisms involved in ethanol reinforcement. A behavioral and neurochemical study in rodents

    Författare :Anna Larsson; Göteborgs universitet; []
    Nyckelord :Acetylcholine; Dopamine; Ethanol; Locomotor activity; Microdialysis; Nicotine; Nicotinic acetylcholine receptors; Rodents; Reward;

    Sammanfattning : Alcohol (ethanol) and smoking (nicotine) are commonly co-abused in human beings. Drugs of abuse interact with the brain mesolimbic dopamine system, an important part of the brain reward system. These dopaminergic neurons originate in the ventral tegmental area and project to e.g. LÄS MER
