Which structure is NOT typically considered part of the basal ganglia circuit?

Explanation:
Understanding basal ganglia circuits means recognizing a network that forms cortico-basal ganglia-thalamo-cortical loops involved in motor control and learned movement. The core players are the caudate nucleus and putamen together (the striatum), plus the globus pallidus, subthalamic nucleus, and substantia nigra. The amygdala, on the other hand, belongs to the limbic system and drives emotion and memory processing. It isn’t a primary node in the classic motor-related basal ganglia loops, even though it does connect with other brain regions. So, the amygdala isn’t typically considered part of the basal ganglia circuit, making it the correct choice.
