Example Sentences

The superior colliculus works like a built-in radar, taking direct signals from the retina before the cortex receives them.

From Science Daily

By using light to activate specific retinal pathways and recording responses in mouse brain slices, they discovered that the superior colliculus can suppress a central visual signal when the surrounding area becomes active -- a defining feature of center-surround processing.

From Science Daily

"We have seen that the superior colliculus not only transmits visual information but also processes and filters it actively, reducing the response to uniform stimuli and enhancing contrasts," says Kuisong Song, co-first author of the paper.

From Science Daily

They show that structures analogous to the superior colliculus -- found in fish, amphibians, reptiles, birds, and mammals -- share a common purpose: merging sensory and motor information to guide gaze and attention.

From Science Daily

The research team is now extending their work to live animal models to study how the superior colliculus shapes attention and controls distraction during goal-directed behavior.
