2. The hindbrain consists of the medulla, pons, and cerebellum. Running through the medulla and pons at the midline is the reticular formation. The midbrain contains the remaining section of the reticular formation, the periaqueductal gray, the red nucleus, the superior colliculi, the inferior colliculi, and the substantia nigra. The forebrain is divided into the diencephalon and the telencephalon. The diencephalon contains the thalamus and hypothalamus.

The telencephalon contains the cerebral cortex, basal ganglia, and limbic system structures. (LO4)
