Coordinated movement: The cerebellum controls coordination, while the motor portion of your cerebral cortex controls voluntary movement. WebThe subthalamic nucleus is part of the diencephalon; as its name implies, it is located just below the thalamus. The substantia nigra is a midbrain structure, composed of two distinct parts: the pars compacta and the pars reticulata. The substantia nigra is located between the red nucleus and the crus cerebri (cerebral peduncle) on the ventral part of the midbrain.
