NURS 5357 NEUROBIOLOGY UPDATED EXAM SCRIPT
QUESTIONS AND SOLUTIONS RATED A+
✔✔What is the effect of aging on dopamine transporter density in ADHD? -
✔✔Dopamine transporter density declines with age, affecting impulse control.
✔✔What is the significance of tau proteins in neurons? - ✔✔They stabilize microtubules
and are essential for neuronal transport.
✔✔What imaging technique shows decreased energy and glucose metabolism in
Alzheimer's? - ✔✔PET scan.
✔✔What is the relationship between dopamine activity and impulsivity in ADHD? -
✔✔Dopamine activity in the nucleus accumbens influences attention and impulsivity.
✔✔What is the role of norepinephrine in ADHD treatment? - ✔✔It helps with signaling
and blocking out irrelevant stimuli.
✔✔What changes occur in the brain due to chronic drug use? - ✔✔It alters the
morphology of dendritic spines in the nucleus accumbens.
✔✔What is the primary culprit in the formation of amyloid plaques? - ✔✔A-beta42
protein cleaved from amyloid precursor protein.
✔✔What is the impact of stimulant medications on norepinephrine and dopamine? -
✔✔They tune norepinephrine and dopamine to improve concentration and impulse
control.
✔✔What are the major types of dementia? - ✔✔Alzheimer's, Frontotemporal, Lewy
Bodies, Vascular, Parkinson's
✔✔What is the concept of 'relapse' in addiction? - ✔✔Relapse refers to the return to
substance use after a period of abstinence.
✔✔What factors can contribute to relapse? - ✔✔Minimal drug use, exposure to cues
associated with drug use, and stress.
✔✔How does the PFC relate to relapse? - ✔✔Inactivation of the PFC prevents relapse.
✔✔What neurotransmitter is increased during relapse? - ✔✔Dopamine (DA) is released
in the NAc during relapse.
