    About the Lecture

    The lecture Direct and Indirect Basal Ganglia Pathway by Craig Canby, PhD is from the course Basal Ganglia. It contains the following chapters:

    • Pathways – Direct
    • Pathways – Indirect
    • Pathways – Nigrostriatal

    Included Quiz Questions

    1. Globus pallidus internus has an inhibitory effect on Thalamus.
    2. Dopamine inhibits the direct pathway.
    3. Inhibition of Globus pallidus by striatum also inhibits thalamus.
    4. Striatum has excitatory effect on Globus pallidus internus.
    5. Direct pathway has an inhibitory effect on cerebral motor cortex.
    1. …Subthalamic nucleus
    2. …Substantia nigra
    3. …Putamen
    4. …Globus pallidus externus
    5. …Globus pallidus internus
    1. Dopamine stimulates direct pathway via D1 receptor and induces motion.
    2. Dopamine inhibits indirect pathway via D2 receptor and inhibits motion.
    3. Dopamine acts on both D1 and D2 receptor and excites both inhibitory and excitatory pathways.
    4. Dopamine inhibits the excitatory pathway.
    5. Dopamine excites the inhibitory pathway.
