Neuroscience Studies: Basal Ganglia

The balance between direct and indirect pathways is crucial for initiating or inhibiting movements.

Dopamine's role extends to include motivation and reward processing.

Understanding the BG can inform treatments through interventions like pharmacotherapy and DBS.
