A)Cerebellar hemisphere
B)Frontal lobe of cortex.
C)Globus pallidus.
D)Inferior Olivery Nucleaus.

For E, you ablate the substantia nigra by a needle, then it is going to
mimic Parkinson, accetuate Tremor.
This question is based on FA2011 p400. It is like that tremor is inhibited
by blocking the pathway.
Not 100% sure |
