Slide 16: Midbrain - Superior Colliculus/Red Nucleus

Identify:

• Superior Colliculus (SC)
• Periaqueductal Gray (PAG)
• Cerebral Aqueduct
• Brachium of the Inferior Colliculus (BIC)
• Medial Lemniscus (ML)
• Spinothalamic Tract (STT)
• Red Nucleus (RN)
• Cerebello-thalamic fibers (CBTh)
• Crus Cerebri
• Corticospinal Tract fibers (CST)
• Substantia Nigra (SN)
• Oculomotor Nucleus (3)
• Oculomotor Nerve Fibers exiting the brainstem in the Interpeduncular Fossa
• Medial Longitudinal Fasciculus (MLF)
• Interstitial Nucleus Of Cajal (INC)
• Central Tegmental Tract (CTT)
• Hypothalamo-Autonomic Tract

Note:

• The Red Nucleus gives rise to the Rubrospinal Tract and is a major termination region for the Superior Cerebellar Peduncles.
