The inferior colliculus has three subdivisions: the central nucleus, a dorsal cortex by which it is surrounded, and an external cortex which is located laterally.he inferior colliculus lies caudal to its counterpart-the superior colliculus-above the trochlear nerve, and at the base of the projection of the medial geniculate nucleus and the lateral geniculate nucleus.
