11. On natural and drug-induced reward : genetic, biochemical and behavioral comparisons
Abstract : Work in this thesis compares natural and drug- induced reward at genetic, biochemical and behavioral levels with the objective to obtain information about key mechanisms underlying reward and addiction, and improve the understanding of compulsive elements that characterize addiction. Surveys among committed human runners have described running as addictive. READ MORE

12. The phencyclidine model of schizophrenia : dysregulation of brain dopamine systems induced by NMDA receptor antagonists
Abstract : Non-competitive NMDA receptor antagonists, such as phencyclidine (PCP) and dizocilpine (MK-801) can even acutely induce a drug induced psychotic state which closely resembles schizophrenia. The midbrain dopamine (DA) neurons, which originate in the ventral tegmental area (VTA), are involved in motivational, attentional and cognitive processes, and have also been profoundly implicated in schizophrenia.

It consists of cell bodies in the ventral tegmental area (VTA) that project to e.g. the nucleus accumbens (NAC), the central nucleus of amygdala (CNA) and the medial prefrontal cortex. READ MORE
