NURS 660 Exam 1 Latest Exam Questions & Answers, All Answers Explained-1. Identify the emerging neurobiological hypothesis of schizophrenia. o The hypothesis: (focus on the most detail with the Dopamine Theory) The only pharmacological treatment that we have are dopamine (D2 receptors) and serotonin (5HT2A) Dopamine Theory ▪ Hyperactive dopamine at D2 receptors in the mesolimbic pathway In the mesolimbic pathway is responsible for the positive symptoms; the hypoactivity is responsible...

mesocortical pathway – executive function: attention, focus, depression nigrostriatal pathway – from substantia nigra (brainstem) to striatum (muscles): Parkinson's mesolimbic pathway – projects to nucleus accumbens (part of limbic system). Pleasure, reward, positive symptoms of schizophrenia: Addiction, gambling Tuberoinfundibular pathway – regulation of prolactin (acts on pituitary). Hypersexuality in mania Dopamine – produced in substania nigra and VTA. D2 & D4 receptors ...

dopamine hypothesis - ANSWER the theory that schizophrenia results from excessive activity of the neurotransmitter dopamine dopamine hypothesis- nigrostriatal pathway - ANSWER The nigrostriatal dopamine pathway that projects from the substantia nigra to the basal ganglia or striatum, is part of the extrapyramidal nervous system and controls motor function and movement. Mesolimbic dopamine hypothesis: Hyperactivity of dopamine neurons in the mesolimbic dopamine pathway cause what sympto...
