Now DeBello and Knudsen identify a second site of plasticity: the superficial layers of the optic tectum (OT), an area that corresponds to the superior colliculus in mammals.

Regarding the researchers' future plans, Dr. Kremkow says: "Now that we understand the functional, mosaic-like connections between retinal ganglion cells and neurons within the superior colliculi ...

Two brain structures are crucial to the processing of visual stimuli: the visual cortex in the primary cerebral cortex and the superior colliculus, a structure in the midbrain. Vision and the ...

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright ...

In turn, the tectum/colliculus signals nerve cells to activate muscles. In mammals, those nerve cells reside in the periaqueductal gray or PAG, a structure in the brain stem.

Chiari Malformation Type II: T1-weighted axial MRIs. These axial scans show several abnormalities, including descent of the cerebellar tonsils (tonsillar herniation), an abnormal midbrain with a ...

In turn, the tectum/colliculus signals nerve cells to activate muscles. In mammals, those nerve cells reside in the periaqueductal gray or PAG, a structure in the brain stem.

Superior colliculus articles from across Nature Portfolio The superior colliculus is one of the anterior pair of round eminences of the midbrain that contribute to visual function, including the ...

However, the superior colliculus did not disappear with the development of the cortex in mammals. In primates, including humans, it has been linked to rapid and unconscious forms of visual processing, ...

"This is useful, because it suggests that the zebrafish tectum, with all of its great experimental attributes, is an appropriate platform for studying how the superior colliculus works, including ...
