Other questions in this quiz

2. Which pathway favours D1 receptors and why?

  • Direct pathway. D1 receptors are excited by dopamine
  • Indirect pathway. D1 receptors are excited by dopamine
  • Direct pathway. D1 receptors are inhibited by dopamine
  • Indirect pathway. D1 receptors are inhibited by dopamine

3. In terms of basal ganglia damage, which of these causes Parkinsons?

  • Unilateral damage to subthalamic nuclei. Unwanted movements
  • Lack of dopamine increases activity of direct pathway. Tonic inhibition of thalamus and less excitation of cortex. Difficulties starting and stopping movements
  • Degeneration of striatum. No inhibition of thalamus, resulting in overexcitability and unwanted movements

4. What connection type does glutamate facilitate?

  • Modulatory connections
  • Excitatory connections
  • Inhibitory connections

5. What is the cerebellum involved in?
