Superior cerebellar peduncle - primary output of the cerebellum with mostly fibers carrying information to the midbrain
Superior colliculus, a paired structure that forms a major component of the vertebrate midbrain

"The IRS2-Akt pathway in midbrain dopaminergic neurons regulates behavioral and cellular responses to opiates."
An example of a healthcare provider order regarding an EVD is: Level external ventricular drain to 15 cmH20 above midbrain, open to drain continuously, check and record cerebrospinal fluid drainage and intracranial pressure every hour.
Denton distinguishes between primordial emotions, "imperious states of arousal and compelling intentions to act" (p.7) driven by activation of interoceptors and involving ancient, lower brain regions such as the medulla, midbrain and hypothalamus, and "classic" emotions, such as anger, fear and love, driven by distance receptors (vision, hearing, olfaction) and mediated by higher, more recently evolved brain regions.
