Verified step by step guidance

Begin by understanding the anatomical location and function of the midbrain. The midbrain, or mesencephalon, is a portion of the brainstem located between the forebrain and the hindbrain.
Identify the structures that are part of the midbrain. The midbrain includes the tectum and tegmentum, which contain various nuclei and tracts.
Focus on the superior colliculi, which are part of the tectum in the midbrain. They are involved in visual processing and reflexive eye movements.
Consider the cerebellum, medulla oblongata, and thalamus. The cerebellum is part of the hindbrain, the medulla oblongata is part of the brainstem but not the midbrain, and the thalamus is part of the forebrain.
Conclude that the superior colliculi are the correct structures associated with the midbrain, while the cerebellum, medulla oblongata, and thalamus are not part of the midbrain.
