Schizophrenia and Parkinson's disease are both linked to changes in which neurotransmitter?

  • A. serotonin
  • B. glutamate
  • C. dopamine
  • D. acetylcholine
Correct Answer: C

Rationale: Dopamine is a neurotransmitter that plays a critical role in regulating mood, motivation, and movement. Schizophrenia is associated with excessive dopamine activity in certain brain regions, leading to symptoms like hallucinations and delusions. In contrast, Parkinson's disease is linked to a deficiency of dopamine in the basal ganglia, resulting in motor symptoms such as tremors and rigidity. Both conditions highlight the importance of dopamine in brain function and the consequences of its dysregulation.

The action potential pattern that appears on the oscilloscope screen is caused by rapid ________.

  • A. polarity changes
  • B. pH changes
  • C. breakdown of the membrane structure
  • D. all of the above
Correct Answer: A

Rationale: The action potential pattern observed on an oscilloscope is caused by rapid changes in membrane polarity. During an action potential, the membrane potential depolarizes (becomes more positive) as sodium ions rush into the neuron, followed by repolarization (returning to negative) as potassium ions exit. These polarity changes are essential for the propagation of nerve impulses and are a hallmark of neural activity.
