Component items:

Auditory Reflexes Nuclei of Midbrain Mesencephalon (MM.REF.AUD)
- Inferior Colliculus (ABA.MM.IC)
  - Central Nucleus of Inferior Colliculus: Integrate and relay auditory information to cortex, detection of pitch, spatial localization by binaural hearing
  - External Nucleus of Inferior Colliculus: Middle ear reflex
- Superior Olivary Complex: Bilateral Audition
Visual Reflexes Nuclei of Midbrain Mesencephalon (MM.REF.VIS)
- Superior Colliculus (MM.SC): Direct behavioral responses toward specific points in egocentric space, induce saccadic eye movement
  - Superficial Superior Colliculus: Head and eye attention to visual stimuli
  - Intermediate Superior Colliculus: Sensimotor integration for orienting
  - Deep Superior Colliculus: Head and eye attention to non-visual stimuli
- Supraoculomotor Area (VBA.MM.SOA): Control of vergence
  - Cajal Nucleus: Integration of head and eye movements, controls downward vertical gaze
  - Rostral Interstitial Nucleus of MLF: Integration of head and eye movements, controls upward vertical gaze
  - Darkschewitsch Nucleus: Mediate the consensual pupillary light reflex
- Pretectum (MM.PT)
  - Anterior Pretectum Nucleus: Mediate somatosensory and nociceptive information
  - Nucleus of Optic Tract: Encode retinal error information during smooth pursuit eye movements
  - Pretectal Olivary Nucleus: Pupillary light reflex and modulating subcortical nuclei involved in circadian rhythms
  - Principal Pretectal Nucleus: Pupillary light reflex
  - Sublentiform Nucleus: Accomodation reflex
