SUPERIOR COLLICULUS
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
An essential visual center between the retina and the striate cortex
Classified under:
Hypernyms ("superior colliculus" is a kind of...):
center; centre; nerve center; nerve centre (a cluster of nerve cells governing a specific bodily process)
Holonyms ("superior colliculus" is a part of...):
mesencephalon; midbrain (the middle portion of the brain)
Context examples:
Each step is handled by different parts of the brain, from the eye’s light-sensing retina to the visual cortex and the superior colliculus.

In essence, this simple differential threshold of neuronal activity in the superior colliculus triggers the animal to report the presence of something in the visual field.

While both sides of the brain activated in response to color changes, the researchers discovered that if the difference in neuronal activity between the two sides reached a specific threshold (e.g., neurons in the right superior colliculus fired more strongly than the left), the monkey would release the lever.

Scientists at the National Eye Institute (NEI) have found that neurons in the superior colliculus, an ancient midbrain structure found in all vertebrates, are key players in allowing us to detect visual objects and events.
