16. Dopamine D2 receptor G protein coupling and it's regulation
Sammanfattning : Dopamine (DA) receptors belong to the superfamily of G protein coupled receptors. The D2 DA receptor is negatively coupled with adenylate cyclase via pertussis toxin sensitive (Gi/o) G proteins. LÄS MER
17. The monoamine stabilizer (-)-OSU6162 : a potential novel treatment for alcohol use disorders
Sammanfattning : Alcohol use disorder (AUD) represent a major health problem worldwide. Despite the severe consequences of AUD, only four medications are approved in Sweden for this disease. In addition, the prescription rates are low, partly due to varying clinical efficacy of these medications. Consequently, new, more effective pharmacotherapies are needed. LÄS MER
18. Effects of antipsychotics on GABA neurons in the basal ganglia of the rat
Sammanfattning : Antipsychotics are used in the treatment of psychosis and, based on their propensities to induce extrapyramidal side effects (EPS), are divided into typical (haloperidol) and atypical (clozapine) subtypes. The incidence of EPS, arises from an imbalance in the neurotransmission between two majorGABAergic pathways of the basal ganglia that connect the striatum directly to the entopeduncular nucleus (EP) and the substantia nigra reticulata or indirectly via the globus pallidus and the subthalamic nucleus.

19. Modulatory effects and interactions of substance P, dopamine and 5-HT in a neuronal network
Sammanfattning : The spinal neuronal network that generates the locomotor rhythm in lamprey contains excitatory and inhibitory interneurons, reticulospinal inputs from the brainstem, and motor neurons. In this thesis, I have studied how the spinal locomotor network cart be modulated by a tachykinin, dopamine and 5- HT that are co-localized in midline neurons situated below the central canal.

20. Catecholaminergic neurotransmission in heart and brain : development of tracers for positron emission tomography
Sammanfattning : The catecholamines norepinephrine and its biosynthetic precursor dopamine are two principal neurotransmitters in the human central nervous system (CNS). Moreover, norepinephrine is a major transmitter substance in the peripheral, autonomic nervous system. LÄS MER
