Intro to Neuro Question: Huntington’s disease causes too much ballistic movement due to which of the following reasons?
Group of answer choices
Loss of the inhibitory connection between the striatum and the globus pallidus external
Loss of the inhibitory connection between the striatum and the globus pallidus internal
Loss of the inhibitory connection between the globus pallidus external and the globus pallidus internal
Increased activity of globus pallidus internal neurons
Is my reasoning correct?
Huntington's disease is characterized by the degeneration of neurons in the striatum, particularly those that project to the globus pallidus external (GPe) in the indirect pathway.
The correct reason for too much ballistic movement in Huntington's disease is:
Loss of the inhibitory connection between the striatum and the globus pallidus external.
This loss weakens the indirect pathway, reducing its ability to suppress unwanted movements, leading to the hyperkinetic symptoms like chorea seen in Huntington's disease.
