There will be decreased frequency of action potentials along the spinothalamic tract.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 neuronsParkinson's Disease results in a(n) (increase or decrease) in D1 mediated effects on striatal medium spiny neurons. This results in excess (inhibition or excitation) of the thalamus and cortex.
