  1. 1. Motion and Emotion : Functional In Vivo Analyses of the Mouse Basal Ganglia

    Författare :Emma Arvidsson; Åsa Wallén-Mackenzie; Cecilia Flores; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dopamine; Basal Ganglia; Reward System; In Vivo Chronoamperometry; Optogenetics; Deep Brain Stimulation; Parkinson’s Disease; Addiction; Glutamate; Vesicular Glutamate Transporter; VGLUT2; Sex; Age; Subthalamic Nucleus; Striatum; Nucleus Accumbens; Ventral Tegmental Area;

    Sammanfattning : A major challenge in the field of neuroscience is to link behavior with specific neuronal circuitries and cellular events. One way of facing this challenge is to identify unique cellular markers and thus have the ability to, through various mouse genetics tools, mimic, manipulate and control various aspects of neuronal activity to decipher their correlation to behavior.

  3. 2. Nicotine sensitization and the effects of extended withdrawal - behavioral, neurochemical and electrophysiological studies in the rat

    Författare :Julia Morud; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Abstinence; Dopamine; Elevated plus-maze; GABA; Inhibitory control; Nicotine; Nucleus accumbens; Sensitization;

    Sammanfattning : Tobacco use is one of the primary factors for global burden of disease and often results in life-long nicotine addiction, only a small percentage users are able to maintain cessation. The life-long addiction together with a high relapse risk might be connected to drug-induced altered neural circuits. LÄS MER

  4. 3. Taurine and dopamine-related effects of ethanol. An experimental study in rodents

    Författare :Lisa Ulenius; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; Alcohol; Caffeine; Nucleus accumbens; Microdialysis;

    Sammanfattning : The reinforcing properties of alcohol (ethanol) are associated with activation of the mesolimbic dopamine system and the concomitant increase in dopamine in the nucleus accumbens (nAc). Changes in this system are thought to be a predominant underlying factor in promoting excessive alcohol intake and alcohol use disorder. LÄS MER

  5. 4. Glycine receptors in the central nervous system - development, distribution and relation to actions of alcohol

    Författare :Susanne Jonsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycine receptor; nucleus accumbens; alcohol; gene expression; dopamine;

    Sammanfattning : The widespread consumption of alcohol and the great socioeconomic impact of alcohol abuse and addiction have contributed to the extensive investigations of this substance. Despite great efforts there is still uncertainty concerning how alcohol exerts its effects and the mechanisms behind the transition from consumption to addiction. LÄS MER

  7. 5. Preclinical investigations of GlyT-1 inhibition as a new concept for treatment of alcohol dependence

    Författare :Helga Lidö Höifödt; Göteborgs universitet; []
    Nyckelord :Psykiatri experimentell ; Neurofarmakologi; alcohol; dependence; dopamine; GlyT-1 inhibition; nucleus accumbens; reward;

    Sammanfattning : Alcohol addiction and abuse is a main contributor to the global burden of disease and is a high public health priority. Alcohol addiction is a chronically relapsing neurobiological disorder affecting multiple neurotransmitter systems. LÄS MER
