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...

How many dopamine pathways in the brain? - Answer - 5 but only 4 associated with schizophrenia Nigrostriatal Dopamine Pathway controls - Answer - motor function and movement (part of EP NS) Nigrostriatal Dopamine Pathway dopamine excess - Answer - Hyperkinetic movements such as tics/dyskinesias mesolimbic dopamine pathway controls - Answer - Pleasure, reward, euphoria of drug abuse and reinforcing behavior Mesolimbic dopamine pathway excess - Answer - delusions and hallucinations - p...

Mesocortical dopamine pathway D. None of the above - B. Mesolimbic dopamine pathway The reactive reward system signals the immediate prospect of pleasure or pain and triggers drug-seeking behavior. A. True B. False - A. True What role does the amygdala play in substance abuse? A. Releases ph...

Week 3 Quiz #1 is C. 1. Volume neurotransmission refers to? The diffusion of neurotransmitter to nearby neurons. 2. Retrograde neurotransmissions refers to? The flow of neurotransmitter from postsynaptic neuron to presynaptic neuron 3. Use the following CYP450 table to hypothesize drug interactions and their clinical significance for a patient on clozapine who carbamazepine, a mood stabilizer? Clozapine levels would decrease, placing the patient at risk for re-emergence of psychotic sym...

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 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...

NR546 / NR 546 Actual Final Exam 2024 Prediction Questions (All correct answers, Already graded A) Which of the following is considered the pleasure center of the brain? A. Cortico-striatal-thalamic-cortical loop B. Mesolimbic dopamine pathway C. Mesocortical dopamine pathway D. None of the above

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...
