Which two structures do you see?

Middle/round structure = putamen
Curve = caudate nucleus

What are two subcircuits in the main basal ganglia circuit?

Striatum -> substantia nigra -> striatum
Pallidum -> subthalamic nucleus -> pallidum

--> dont forget that there are more afferent connections towards the substantia nigra and subthalamic nucleus!
