Line 20:

The processing of basic sensory information is lateralized by being divided into left and right sides of the body or the space around the body.

In [[visual perception|vision]], about half the neurons of the [[optic nerve]] from each eye [[Optic chiasm|cross]] to project to the opposite hemisphere, and about half do not cross to project to the hemisphere on the same side.<ref>{{Cite web|url=https://theodora.com/anatomy/the_optic_nerve.html|title = The Optic Nerve - Human Anatomy | work = Photius Coutsoukis }}</ref> This meansorganizes visual information so that the left side of the visual field is processed largely by the [[visual cortex]] of the right hemisphere and vice versa for the right side of the visual field.

In [[hearing]], about 90% of the neurons of the [[auditory nerve]] from one ear cross to project to the [[auditory cortex]] of the opposite hemisphere.
