Basal Ganglia |
Associated with functions including: control of voluntary motor movements, procedural learning, routine behaviors, eye movements, cognition and emotion. |

|
Huntington's Disease |
Striatal inhibitory neurons of the indirect pathway degenerate, leading to insufficient inhibitory output of GPi and excessive movement generation. |
|
|
Parkinson's Disease |
The dopaminergic neurons of the SNc degenerate, unbalancing their modulatory effects on the striatum (putamen and caudate nucleus). Direct pathway output of the striatum is weakened and indirect output is strengthened, leading to excessive inhibitory output of GPi, suppressing movement generation. |
