Question

From where do the basal ganglia pathways (starting at the striatum) receive their input?

a. Cerebellum
b. Spinal Cord
c. Cortex
d. Brainstem

Answer 1

The basal ganglia pathways, starting at the striatum, receive input from the cortex.

Step-by-step explanation:

The basal ganglia pathways, starting at the striatum, receive their input from the cortex. The basal nuclei in the cerebrum receive input from the cortex into the striatum. The direct pathway is the projection of axons from the striatum to the globus pallidus internal segment (GPi) and the substantia nigra pars reticulata (SNr), while the indirect pathway involves axons from the striatum to the globus pallidus external segment (GPe), then to the subthalamic nucleus (STN), and finally to GPI/SNr.
