| The brainstem has been cut through the inferior colliculi and the decussation of the superior cerebellar peduncles. |
|
| This decussation occurs in the midbrain tegmentum at the level of the inferior colliculi. |
|
| The posterior thalamic or pulvinar nuclei project backwards over the superior colliculi of the midbrain. |
|
| Normally it extends caudally over the superior colliculi of the midbrain. |
|
| The subcortical pathway activating the amygdala passes through the superior colliculi and the pulvinar of the thalamus before accessing it. |
|
| The tectum is formed by the superior colliculi which is related to the visual system and the inferior colliculi which are part of the auditory system. |
|
| The normal pineal gland secretes melatonin and is located in the supratentorial midline, above the superior colliculi and below the vein of Galen. |
|
| The osseous component of the MMOLC is the medial malleolus, which is composed of the anterior and posterior colliculi separated by the intercollicular groove. |
