NURS 660 Exam 1 Study Guide 2023. Pathways in schizophrenia  Brain imaging shows cerebral atrophy and enlarged fluid filled ventricles, as well as shrinkage in prefrontal cortex, temporal, basal ganglia, and limbic regions like hippocampus.  Five dopamine pathways in the brain. The neuroanatomy of dopamine neuronal pathways in the brain can explain the symptoms of schizophrenia as well as the therapeutic effects and side effects of antipsychotic drugs. Know different pathways in th...

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...

dopamine hypothesis correct answer: the theory that schizophrenia results from excessive activity of the neurotransmitter dopamine What is the path of dopamine suppression by 5-HT? correct answer: 5-HT2A antagonism by atypical antipsychotics decrease serotonin release, thereby stimulating downstream dopamine. Increased dopamine reduces glutamate which inhibits release of inhibitory GABA (inhibits dopamine) Mesolimbic dopamine hypothesis: Hyperactivity of dopamine neurons in the mesolimbi...
