Each of the two colliculi one on each side of the brain contains a two-dimensional map representing half of the visual field.
The tectum comprises the paired structure of the superior and inferior colliculi and is the dorsal covering of the cerebral aqueduct.
Continuing in a rostral direction, the large bumps are called the facial colliculi.
The inferior colliculi together with the superior colliculi form the eminences of the corpora quadrigemina, and also part of the tectal region of the midbrain.
Mesomeres, m1 and m2, becomesthe midbrain, which contains the superior and inferior colliculi.
The brains of the mice were studied and most of the cerebellum, colliculi, and cranial nerves 3 and 4 were missing.
This is the case in lower animals, but in humans, the theory that eye-muscle nuclei aside from the superior colliculi of the midbrain is now generally held.
They are joined to each other across the middle line by the anterior medullary velum, and can be followed upward as far as the inferior colliculi, under which they disappear.
