Direct vs indirect pathway basal ganglia
WebThis pathway is defined as the direct pathway through the basal ganglia. There is another indirect pathway present between the corpus striatum and part of the globus pallidus. This indirect pathway also involves the subthalamic nucleus (a part of the thalamus), which receives signals from the cerebral cortex.
