|Brain: Optic chiasm| |Visual pathway with optic chiasm (X shape
outlined, red) (1543 image from Andreas Vesalius' Fabrica)|
|Gray's||subject #197 883| Specifically, in the optic chiasm,
the nerves connected to the right eye that attend to the right
temporal visual field (located in the nasal portion of the right
retina) cross to the left half of the brain, while the nerves
from the left eye that attend to the left temporal visual field
(located in the nasal portion of the left retina) cross to the
right half of the brain. Optic chiasm in cats In Siamese cats
with certain genotypes of the albino gene, this wiring is
disrupted, with less of the nerve-crossing than is normal, as a
number of scholars have reported.  To compensate for lack of
crossing in their brains, they cross their eyes (strabismus).
